Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technology in the utility model creation
Feature, can be with combination of interactions under the premise of not conflicting conflict.
Embodiment 1: as shown in Figure 1, a kind of binary channels parallel heat exchange device, including coolant channel 1 and refrigerating medium channel
2, the coolant channel 1 and refrigerating medium channel 2 are respectively two mutually independent metallic conduits, the coolant channel 1 by
Aluminium alloy is made, and section is in long strip, internal to form multiple metallic micro channels 11, the refrigerating by the way that several partitions are arranged
Agent channel 2 is TP2 copper pipe, and section is equally in long strip, and the section in the coolant channel 1 and refrigerating medium channel 2 is at least
With a straight flange, two straight flanges are close to each other and there are gap, which is 3.0~6.0mm, and the present embodiment is chosen
3.0mm forms heat transfer as pure aluminum metal (molten point of its molten point lower than aluminium alloy used in coolant channel) solidification in the gap
Dielectric layer 3.
Embodiment 2: it is with the difference of embodiment 1 between adjacent two straight flange of the coolant channel and refrigerating medium channel
Gap width be 6.0mm, also fill up the heat transfer medium layer for being solidified and being formed by fine aluminium in gap.
This binary channels parallel heat exchange device has the advantages that
1. considerably increasing heat-exchange surface than circular pipe structure under identical volume conditions using microchannel
Product, to reduce required volume, reduces costs.2. safety, since refrigerating medium channel and coolant channel are respective independence
Channel, conduction thermal energy is the transmitting that thermal energy is carried out by the thermally conductive aluminum metal with a thickness of 3~6mm, so, when refrigerating medium is logical
When road is due to microthermal climate (0 DEG C or less) or water pump power disappearance (in cold energy transmitting), refrigerating medium (water) will be because of environment temperature
When evaporating temperature is lower than 0 DEG C when degree is less than 0 DEG C or when cold energy exchanges, refrigerating medium channel leads to refrigerating medium (water) volume because of icing
Become larger and bursts channel.Due to coolant channel and refrigerating medium interchannel and non-direct contact, when refrigerating medium channel is because freezing
And after bursting, refrigerating medium (water) will not be caused to mix with refrigerant because of refrigerating medium passageway rupture, not so as to avoid two kinds
It mixes after being burst with medium because of the icing of refrigerating medium channel so that entire heat pump and operation of air conditioning systems or air-conditioning heat pump are set
Standby refrigerant circulating system is mixed with refrigerating medium water phase, to ensure that heat pump and operation of air conditioning systems or air-conditioning heat pump equipment
Therefore it does not scrap.
When air-source or water source heat pump water heater, low temperature heat collector and water-cooled air conditioner use such binary channels
Parallel heat exchange device improves heat exchanger effectiveness since coolant channel uses microchannel.Due to by coolant channel
It is designed to be placed in parallel with two channel of refrigerating medium channel, the spacing distance between adjacency channel is 3~6mm, and is led using fine aluminium
Thermometal makees heat transfer medium, thus heat loss when reducing heat exchange.Because be binary channels design and its between have heat-conducting metal
As buffering, foring has three interlayers every therefore having sufficient anti-swelliong power, to guarantee refrigerating medium channel between two channels
Refrigerating medium (water) be unlikely to refrigerant and refrigerating medium is caused to mix due to icing and cause air-source or water resource heat pump hot water
Device, low temperature heat collector and water-cooled air conditioner are damaged and are scrapped.
The better embodiment of the utility model is illustrated above, but the utility model creation is not limited to
The embodiment, those skilled in the art can also make various etc. without departing from the spirit of the present invention
Same variation or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
