Definitions
- each wick part of the chamber body plate and the chamber cover plate is interviewed.
- a bonding process of welding the chamber body plate and the chamber cover plate may be additionally performed.
- the vapor chamber 10 produced by the manufacturing method according to an embodiment of the present invention is one of the heat dissipation parts that can apply a heat dissipation method of the concept of excluding the induction of phase change of the refrigerant by the compressor, using a compressor. It is a typical radiator designed to cool a specific heating element that is electrically driven and generates heat by transferring heat while causing a phase change only by heat supplied from the outside in an atmospheric pressure state without heat transfer.
- the plurality of pores formed in the wick unit 14 when the incoming refrigerant is a gaseous refrigerant, passes through it directly, but relatively low heat and In addition to performing the function of increasing the heat transfer area during exchange, when the incoming refrigerant is a liquid refrigerant, it rapidly induces a state change to the gaseous refrigerant while increasing the heat transfer area with the liquid refrigerant, and in addition, the size of the pores Accordingly, it is possible to perform a function of more actively inducing a flow of the liquid refrigerant by inducing a capillary phenomenon according to the surface tension property of the liquid refrigerant.
- the plurality of pores formed in the wick part 14 are phase-converted into the liquid refrigerant in the wick part 14 on the side of the chamber cover plate 12 where the gaseous refrigerant flows and accumulates, and then the vacuum layer Along the periphery of (19), it flows again to the side of the wick part 14 close to the heating element 7 among the inner surfaces of the chamber body plate 11, and the liquid refrigerant moves smoothly by its surface tension or capillary force. It is desirable to form
- a plurality of pores formed in a portion of the wick portion 14 in contact with the inner surfaces of the chamber body plate 11 and the chamber cover plate 12 are pores between Ni plating layers formed through an electroless Ni plating process to be described later using aluminum powder
- the liquid refrigerant after heat exchange may be provided to communicate with a capillary pattern passage (not shown) provided so that the liquid refrigerant after heat exchange flows back to the heat generating element 7 through capillary force through surface tension.
- the chamber body plate 11 and the chamber cover plate 12 including the wick part 14 may be fastened to the case 16 or the heat sink of an electronic device requiring heat dissipation using fastening screws 15. .
- sulfuric acid H 2 SO 4
- nitric acid HNO 3
- a Ni plating layer of a predetermined thickness is formed on the outer surface of the particle (particle) unit aluminum powder, and in the process of forming the Ni plating layer, it is combined with a number of other nearby particle (particle) unit aluminum powder to form a so-called cluster unit. It can be clustered in size, and the plurality of pores are formed between particles (particles).
- the above-described Ni plating layer is formed on the outer surface of the aluminum powder formed in particle (particle) units and cluster units by the electroless Ni plating process (S20), and at the same time, the chamber body plate 11 or the chamber cover plate 12
- the aluminum powder in particle unit and cluster unit may be combined by the Ni plating layer.
- the coupling method of the chamber cover plate 12 to the chamber body plate 11 is not limited to the welding coupling method, and any coupling method can be employed as long as the refrigerant filled therein does not leak. something to do.
- the wick part 14 manufactured through the electroless Ni plating process (S20) is coupled to the inner surface of the chamber body plate 11 or the chamber cover plate 12 with a predetermined bonding force as described above, but the sintering process Compared to the case of manufacturing the wick part 14 through the process, the bonding force may be smaller, so the manufacturing method of the vapor chamber according to an embodiment of the present invention may further include a wet Cu plating process (S30).
- the increase in the predetermined bonding force of the wick part 14 to the chamber body plate 11 and the predetermined bonding force of the wick part 14 to the chamber cover plate 12 is such that the wick part 14 and the chamber body plate 11 ) and the separation and separation of the wick part 14 and the chamber cover plate 12 can be minimized, whereby the heat of the chamber body plate 11 transferred from the heating element 7 is transferred to the wick part 14.
- High thermal conductivity As it can be delivered while having, it can have the advantage of greatly increasing the overall thermal conductivity.
- a plurality of pores may be formed by the electroless Ni plating process (S20) of the aluminum powder filled in the refrigerant filling space, and the plurality of pores formed in the wick part 14 are particles It is formed by the Ni plating layer formed on the outer surface of the (particle unit) or cluster unit aluminum powder, and as described above, the wet Cu plating process (S30) forms a size that allows the refrigerant to flow by the capillary phenomenon Ni It can be defined as formed by additionally plating a Cu plating layer on the outer surface of the plating layer.
- the predetermined bonding force between the inner surface of the chamber body plate 11 and the wick part 14 and between the inner surface of the chamber cover plate 12 and the wick part 14 is increased by the addition of the wet Cu plating process (S30). can be further increased. Therefore, as described above, it is possible to create an advantage in that the heat generated from the heating element 7 is smoothly dissipated to the outside while maintaining higher thermal conductivity.
- the chamber body plate ( 11) and each wick part 14 of the chamber cover plate 12 may be additionally performed by welding the chamber body plate 11 and the chamber cover plate 12 so as to be interviewed.
- the wick part 14 is filled in the chamber body plate 11 and then coupled to each other through the electroless Ni plating process (S20) and the wet Cu plating process (S30) described above.
- a joining process in which only (12) is welded may be adopted.
- the outer surface of the wick portion 14 that contacts the inner surface of the chamber cover plate 12 is uneven in that a plurality of pores are formed only by the Ni plating process (S20).
- a portion in contact with the inner surface of the chamber cover plate 12 is formed by using a laser processing machine (not shown) to form a predetermined shape that communicates with a plurality of pores.
- a capillary pattern passage (not shown) may be formed.
- the inner surface of the chamber cover plate 12 and the outer surface of the wick part 14 having the capillary pattern passage processed are mutually interviewed with each other on the chamber body.
- the chamber cover plate 12 may be coupled by any one of the above-described welding coupling method and various coupling methods so as to cover the open outer surface of the plate 11 .
- Figure 4 is a microscopic comparison photograph for comparing the particle size, cluster size and pore size of a Cu powder sintered product (a) through a sintering process and an Al powder sintered product (b) prepared by the manufacturing method of an embodiment of the present invention
- 5 is a microscopic comparison photograph for comparing the overall distance between particles of a Cu powder sintered product (a) through a sintering process and an Al powder sintered product (b) manufactured by the manufacturing method of an embodiment of the present invention.
- FIG. 4 is a 300-fold enlarged photograph of the wick part 14 manufactured by the manufacturing method according to an embodiment of the present invention, chemical bonding between each particle (particles), and pores in the cluster is open, and the pores between the clusters are also open, which visually confirms that the capillary force is relatively improved.
- the wick part 14 manufactured by the manufacturing method of one embodiment of the present invention has a size of approximately 100 ⁇ m, and the particles of the sintered product referred to in FIG. It can be seen that when formed in a size (approximately 130 ⁇ m) and generally forming a cluster, larger pores are formed to improve capillary force.
