Description
Technical field
It is the heat exchanger components of purpose that the utility model relates between two kinds of fluids with the heat exchange; Be particularly related to a kind of integrated form micro-channel heat exchanger that can be used as the transmission of carrying out heat energy between water and the refrigeration working medium.
Background technology
In the present field of heat exchangers, micro-channel heat exchanger can satisfy the requirement of compact heat exchanger owing to volume, weight are less relatively, is the new direction of current heat exchanger research and development.
The existing micro-channel heat exchanger that is used for heat pump nearly all is to add that with the aluminum flat tube section bar import and export of refrigeration working medium and working fluid realize, it only limits to the branch type heat exchanger that the heat exchange between refrigeration working medium and the air is used.For example, the disclosed a kind of micro-channel heat exchanger of Chinese patent file CN102095285A is above-mentioned branch type heat exchanger.Because the heat exchange flat tube is the aluminum pipe section bar, section bar is of a size of definite value.Select that for the hydraulic diameter of microchannel restriction is arranged, be difficult to choose the later aluminum pipe section bar of Optimal Structure Designing.Also have; Produced aluminum pipe section bar technology limitation at present; The size (require wall thickness very thin) that wall thickness between the microchannel can not accomplish to conduct heat requirement like this, uses flat tube just can not become the developing direction of micro-channel heat exchanger technology as the micro-channel heat exchanger of aluminum pipe profile design.
