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.
