It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
As shown in figure 1, the present embodiment net formula heat exchanger, including isocon 1, collecting pipe 2 and radiating subassembly 3, the radiating
It is in be formed with some interconnected refrigerant flow paths 31 in hollow type network, the radiating subassembly 3 that component 3 is overall,
The radiating subassembly 3 is connected between the isocon 1 and the collecting pipe 2.
Specifically, refrigerant is input to the refrigeration in radiating subassembly 3 by isocon 1 by the present embodiment net formula heat exchanger
Agent runner 31, and because radiating subassembly 3 is internally formed some interconnected refrigerant flow paths 31, different refrigerant flow paths
31 junctions will form refrigerant distributary division or refrigerant merging part, and refrigerant is in the flow process of refrigerant flow path 31, refrigeration
At the same time agent, will be in hollow type network because radiating subassembly 3 is overall, outside by repeatedly shunting, interflow cross flow one
The engraved structure through the formation of radiating subassembly 3 of portion's air, can cause air more efficiently to be changed with radiating subassembly 3
Heat, compared to finned heat exchanger, the coefficient of heat transfer between improving inside and outside heat exchanger eliminates the exchange such as thermal contact resistance, dust stratification
The adverse effect of heat, greatly improves the heat transfer coefficient of heat exchanger.The refrigerant flow path 31 of radiating subassembly 3 is without swollen after aluminum fin-stock flange
Copper pipe outer surface is connected on, the thermal contact resistance that existing finned heat exchanger is produced by copper pipe outer surface expanded joint aluminum fin-stock is eliminated, separately
Outside, it, without rib structure, is 100% equivalent to fin efficiency to be outside the pipe of refrigerant flow path 31.Due to outside pipe without arranging close fin
Structure, heat exchange pipe external surface is difficult to accumulate dust, and substantially reduces adverse effect of the dust stratification to heat transfer.In summary factor, this
Can be reached by planting the heat transfer coefficient of cellular heat exchanger heat exchanger by 600W/m2 DEG C or so, and nearly one is improved than finned heat exchanger
The individual order of magnitude.
In actual use, net formula heat exchanger can also be used as condenser as evaporator.For example：Refrigeration

Shunting, interflow cross flow one, while being exchanged heat with the air outside pipe, refrigerant is evaporated to gaseous state, into collecting pipe 2 after stream
Go out；Air side：Direction of the air along vertical paper is flowed vertically through in the engraved structure and refrigerant flow path 31 of the formation of radiating subassembly 3
The quick heat exchange of refrigerant.Net formula heat exchanger is used as condenser, refrigerant side when heating：The refrigerant of gas phase enters collecting pipe
2, flowed downward along along each branched pipe pipe being connected with collecting pipe 2, during flowing downward, refrigerant is in different refrigerants
By repeatedly shunting, interflow cross flow one in runner 31, meanwhile, exchanged heat with the air outside pipe, refrigerant is condensed into liquid,
Flowed out after into isocon 1；Air side：Direction of the air along vertical paper flows vertically through the engraved structure of the formation of radiating subassembly 3
With the quick heat exchange of refrigerant in refrigerant flow path 31.
Wherein, in order to more effectively improve heat exchange efficiency, the inside caliber of refrigerant flow path 31 is 0.5~3mm, the system
The outside wall thickness of refrigerant flow conduit 31 is 0.15~0.3mm.The coefficient of heat transfer of net formula heat exchanger is compared to the existing copper of use Φ more than 7
The fin-tube heat exchanger of pipe is much greater, further, since the interlaced connection of refrigerant flow path 31, refrigerant is multiple in pipe
Shunting, interflow cross flow one, it is very big to tube refrigerant and the flow disturbance for managing outer air, also significantly enhance in pipe, outside pipe
Heat exchange.And the hollow type network that radiating subassembly 3 shows can be polygonized structure, it is preferred that hollow type grid knot
Structure is hexagonal honeycomb structure, and the refrigerant flow path length for forming the vertical section of the hexagonal honeycomb structure is L1, shape
The refrigerant flow path length into the tilting section of the hexagonal honeycomb structure is L2；L1：L2=1：（1~1.5）, form institute
