The heat exchanger comprises a shell and a bottom cover, and heat exchange tubes are arranged in a sealed cavity formed by the shell and the bottom cover. The heat exchanger is characterized in that the heat exchange tubes include at least one group of spiral tubes, each group of spiral tubes includes more than two parallel spiral sub-tubes in same length, the bottom end of each spiral sub-tube is connected to a main feed pipe, and the top end thereof is connected to a main discharge pipe. An overturning structure capable of changing positions of the internal spiral sub-tube and the external spiral sub-tube side by side by 180 degrees is arranged in the middle of each group of the spiral tubes, so that heat radiation area is enlarged, positions of the parallel spiral sub-tubes can be changed after 180-degree overturning, integral heat radiation is uniform, heat exchange efficiency is high, and size is small. Since a coolant inlet and a coolant outlet of the sealing cavity and cooled medium inlets and outlets of the heat exchange tubes are led from the bottom cover, the heat exchanger is convenient to clean and maintain.
Description
Technical field
The present invention relates to the cooling device technical field, be specifically related to the heat converter structure improvement aspect that adopts the spiral heat-exchange tube to cool off.
Background technology
At present, for liquid or gas are cooled off, generally be to adopt high-temperature fluid or gas are imported in the spiral helicine heat-exchange tube, heat-exchange tube places cooling fluid, absorb heat-exchange tube by cooling fluid and conduct the heat that, reach cooling, the purpose of heat exchange.And present heat-exchange tube is higher owing to the less segment temperature in interval in the heat-exchange tube, and bigger at interval segment temperature is lower, and the heat that cooling fluid absorbs fails in time to be spread apart, and it is inhomogeneous to dispel the heat, and heat exchanger effectiveness is low.
Summary of the invention
In sum, the objective of the invention is to solve present heat exchanger and exist heat radiation inhomogeneous, the technical deficiency of heat exchanger effectiveness, and a kind of heat exchanger is proposed.
For solving technical problem proposed by the invention, the technical scheme of employing is: a kind of heat exchanger, include shell and bottom, and in the annular seal space of shell and bottom formation, be provided with heat-exchange tube; It is characterized in that: described heat-exchange tube includes one group of helix tube at least, and every group of helix tube constitutes by two identical spiral pipes side by side of above total length, and each spiral pipe bottom all is connected on the charging house steward, and the top all is connected on the discharge header pipe; Every group of helix tube is formed with a torsion structure that will and come internal helicoid pipe and external helicoid pipe location swap 180 degree at medium position.
When described helix tube is more than two groups the time, each spiral ring layer of organizing helix tube is stacked setting at interval.
The center of described bottom is provided with three-way connection, and straight-through section center line of three-way connection and the central lines of bottom are socketed with a cooling fluid water conservancy diversion sleeve pipe that places each helix tube inner ring on the top of three-way connection; Described charging house steward draws through described bottom non-central location, and described discharge header pipe is connected with one through straight-through section discharging straight tube of drawing of described cooling fluid water conservancy diversion sleeve pipe and three-way connection; Be positioned at cooling fluid water conservancy diversion sleeve pipe periphery at bottom and be provided with cooling liquid inlet, remain with the gap between straight-through section inwall of described discharging straight tube outer wall and three-way connection, the side of three-way connection is cooling liquid outlet.
Be filled with the cooling fluid membrane layer between the inwall of described heat-exchange tube and shell.
Top or the bottom of described heat-exchange tube are provided with sealing ring.
Be provided with elasticity between each helical layer ring layer of described each helix tube and separate fastener.
The bottom of described shell is tightly connected by ring flange and bottom.
The cooling fluid import and export of described annular seal space, and the import and export of the medium that is cooled of heat-exchange tube is drawn by described bottom.
The spiral pipe that constitutes described heat-exchange tube adopts the following conduit of diameter 10mm.
Beneficial effect of the present invention is: the spiral pipe that heat-exchange tube of the present invention includes more than two side by side constitutes many group helix tubes; Each spiral ring layer of organizing helix tube is stacked setting at interval; Every group of helix tube is formed with a torsion structure that will and come internal helicoid pipe and external helicoid pipe location swap 180 degree at medium position, not only enlarged radiating surface, after 180 degree reverse, each spiral pipe position side by side will be changed, and makes integral heat sink even, the heat exchanger effectiveness height, and volume is little, because the cooling fluid import and export of annular seal space, and the import and export of the medium that is cooled of heat-exchange tube draws by described bottom, then makes things convenient for clean and maintenance.The present invention can also oppositely use except can cooling off usefulness to the meson in the heat-exchange tube, that is to say the meson in the heat-exchange tube is oppositely heated usefulness.
