Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
As shown in Figure 1, the present embodiment net formula heat exchanger, including isocon 1, collecting pipe 2 and radiating subassembly 3, the heat dissipation
Whole component 3 is in hollow type network, and several interconnected refrigerant flow paths 31 are formed in the radiating subassembly 3,
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 since 3 inside of radiating subassembly forms several interconnected refrigerant flow paths 31, different refrigerant flow paths
31 junctions will form refrigerant distributary division or refrigerant merging part, and refrigerant is in 31 flow process of refrigerant flow path, refrigeration
Agent will pass through multiple shunting, interflow cross flow one, be in hollow type network since radiating subassembly 3 is whole, outside at the same time
Portion's air passes through the engraved structure that radiating subassembly 3 is formed, and air can be caused 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 exchanges 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, eliminates the thermal contact resistance that existing finned heat exchanger is generated by copper pipe outer surface expanded joint aluminum fin-stock, separately
Outside, it is no rib structure outside the pipe of refrigerant flow path 31, it is 100% to be equivalent to fin efficiency.Due to outside pipe without arranging close fin
Structure, heat exchange pipe external surface are not easy to accumulate dust, and substantially reduce adverse effect of the dust stratification to heat transfer.In summary factor, this
The heat transfer coefficient of the cellular heat exchanger heat exchanger of kind can reach 600W/m2 DEG C or so, and nearly one is improved than finned heat exchanger
A order of magnitude.
In actual use, net formula heat exchanger can be used as evaporator, can also be used as condenser.Such as：Refrigeration
