Abstract

The utility model relates to a needling type heat dissipating device with a heat pipe plate. The utility model is mainly composed of an installing plate on which a heat conducting bottom plate is inlaid and a heat pipe plate, on the wall of which a group of heat dissipating fin sheets are arranged in a lifting mode. A sealing cap fixedly connected with the top of the heat pipe panel is provided with a vacuum pumping nozzle, and heat conducting media arranged in a vacuum chamber rapidly sublimate after heated and are diffused in the vacuum chamber, so that the temperature difference of both ends of the heat pipe plate can be reduced farthest, and zero contact resistance with heat sources can be realized. With the integrative optimum design, the utility model can fully realize the heat dissipating effect of heat pipes and The has the advantages of simple structure, convenient installation and use, strong heat dissipating capacity, stable working performance and no mechanical vibration and noise pollution. The utility model is especially suitable for heat dissipating components of CPU chips of large and medium computer systems.

Description

Aculeus type heat tubesheet heat abstractor

Technical field:

The utility model relates to a kind of cooling heat radiator, specifically a kind of aculeus type heat tubesheet heat abstractor, and it is particularly suitable for the thermal component of computer system CPU chip, also can be applicable to make radiating appliance in the general heat-exchange device.

Background technology:

Computer system in the course of the work, its cpu chip can generate heat, when the temperature rise of cpu chip is too high, to influence computing machine normal and stable operation performance, also can cause the security incident that burns out computer equipment when serious, just present, be the serviceability of guaranteeing that computer system security is stable, to the cpu chip of heating is to adopt electric fan to force the processing of lowering the temperature of the mode of blowing cooling heat dissipation, though this mode also can be carried out radiating and cooling to cpu chip, but electric fan should consumed power in the course of work of blowing cooling heat dissipation, also can produce noise and vibration, the working environment of the computing machine that deteriorated significantly.Even more serious is, computing machine in the course of the work, if because certain imponderable factor generation cooling fan outage or physical damage are when quitting work, generally speaking, people also are difficult in time find, the temperature of the cpu chip of at this moment working can sharply rise, and the accident of scaling loss equipment can take place when serious.

Summary of the invention:

The utility model be propose on the basis of existing technology a kind of simple in structure, easy to install, strong and the stable work in work of heat-sinking capability, the aculeus type heat tubesheet heat abstractor that does not have machinery vibration and noise pollution during work, it mainly is made of installing plate and heat tubesheet, on the wall of heat tubesheet, gather to choose and be shaped on one group of aculeus type radiating fin, can increase the efficiently radiates heat area of heat tubesheet, it is characterized in that the conductive sole plate that is fixedly connected on the heat tubesheet bottom is flush-mounted in installing plate, the sealing cap that is fixedly connected on the heat tubesheet top has been done and has been vacuumized mouth, heat tubesheet is evacuated vacuumize mouth with silver-colored end socket behind the chamber and firmly seal, at the vacuum intracavitary unit heat-conducting medium is arranged, when installing and using, the conductive sole plate that is flush-mounted in installing plate is adjacent to cpu chip, the heat that is produced during cpu chip work is conducted to heat tubesheet by conductive sole plate, heat-conducting medium is heated and distils rapidly and fill the air in vacuum chamber, the heat that is produced in the time of cpu chip can being worked conducts to heat tubesheet top fast, can heat be distributed rapidly by one group of aculeus type radiating fin of the system of choosing of gathering on the whole tube sheet wall of heat tubesheet and take away.
