The purpose of this utility model overcomes above-mentioned deficiency of the prior art, provides a kind of and can reduce windage, easily realizes that wind path controls, the contact area of air and metal fin maximizes, effective heat dissipation metal chip heat exchange device for air improving the carrying liqs circulation pipe of heat exchange efficiency.

In order to reach above-mentioned technique effect, the utility model takes following technical scheme:

The very little metal fin battle array of one deck pitch of fins is respectively dispersed with in intermediate thermal conductivity plate both sides, namely be made up of metal fin more than two panels, cold and hot different air oppositely flows into from heat-conducting plate both sides respectively, and metal fin is heated or freezes, the heat on metal fin realizes the exchange of both sides air energy respectively to both sides conduction by intermediate thermal conductivity plate.

A kind of heat dissipation metal chip heat exchange device for air, it is formed by the pressing of plural same metal fin, every sheet metal fin has three reinforcements, metal fin be divide into uniformly four regions, and the reinforcement of centre is large compared with upper and lower two reinforcements; Because reinforcement defines four holes between adjacent metal fin, whole heat exchange device for air defines four rounds, upper two rounds are combined into metal fin battle array, lower two rounds are combined into lower metal fin battle array, hot-air flows into from upper metal fin battle array and lower metal fin battle array with relative direction with cold air, heats or freeze to metal fin; Form the heat-conducting plate vertical with metal fin after reinforcement pressing in the middle of metal fin, the heat on metal fin realizes the exchange of both sides air energy respectively to the conduction of upper and lower both sides by heat-conducting plate; Cover plate is equipped with respectively in the metal fin top of pressing and bottom.

In structured design process, may occur structure outstanding appear excessive, or the situation that span is excessive, under these circumstances, the load that the joint face of structural member itself can bear is limited, then on the public vertical plane of two combinations, increase by one piece of stiffener, be commonly called as reinforcement, to increase the intensity of faying face.

According to a preferred embodiment of the present utility model, described metal fin is the sheet metal being selected from aluminium foil, Copper Foil, goldleaf or silver foil.Consider preparation cost and process conditions problem, often select aluminium foil or Copper Foil.

According to another preferred embodiment of the present utility model, described metal fin thickness is 1-2mm.

According to another preferred embodiment of the present utility model, described metal fin thickness is 1.1-1.3mm.In general, the thickness of metal fin is that thinner heat exchanger effectiveness is higher, but metal fin is thinner, higher to its technological requirement, and excessively thin metal fin stress is relatively little.

According to another preferred embodiment of the present utility model, described pitch of holes is 2.5-4mm.

According to another preferred embodiment of the present utility model, described pitch of holes is 3-3.8mm.The pitch of holes of metal fin is also that less heat exchanger effectiveness is higher, and due to the restriction of cost and process conditions, the utility model have selected comparatively suitable pitch of holes.

In conjunction with the consideration of the restriction of production cost and process conditions, the utility model have selected most suitable metal fin thickness and pitch of holes, has both achieved High Efficiency Thermal and has exchanged and again save cost, and reduced the complexity of production.

According to another preferred embodiment of the present utility model, described reinforcement is prepared from by aluminium or copper, and the heat-conducting plate thickness that the reinforcement pressing of centre is formed is 6-8mm.

According to another preferred embodiment of the present utility model, described cover plate is prepared from by aluminium or copper.

The utility model compared with prior art, has following beneficial effect:

The utility model compared with prior art, windage in effective reduction use procedure, more easily realize the control of wind path when parallel ventilation branch, and heat exchange area is balanced, the contact area of air and metal fin maximizes, and equipment simply and effectively improve heat exchanger effectiveness.

Detailed description of the invention

Below in conjunction with embodiments of the invention, the utility model is further elaborated.

Embodiment 1:

A kind of heat dissipation metal chip heat exchange device for air, it is that identical aluminum metal fin 6 pressing being 1.2mm by plural thickness forms, every sheet metal fin there are three reinforcements 7, metal fin 6 be divide into uniformly four regions, and the reinforcement of centre is large compared with upper and lower two reinforcements; Because reinforcement 7 defines the hole 1 that four pitchs of holes are 3.6mm between adjacent metal fin 6, whole heat exchange device for air defines four rounds, upper two rounds are combined into metal fin battle array 2, lower two rounds are combined into lower metal fin battle array 3, hot-air flows into from upper metal fin battle array 2 and lower metal fin battle array 3 with relative direction with cold air, heats or freeze to metal fin 6; Form the thick heat-conducting plate 4 of the 7.6mm vertical with metal fin 6 after reinforcement pressing in the middle of metal fin 6, the heat on metal fin 6 realizes the exchange of both sides air energy respectively to the conduction of upper and lower both sides by heat-conducting plate 4; Metal fin 6 top of pressing and bottom are equipped with cover plate 5 respectively.
