In the embodiment shown in
A heat insulating space 40 or heat insulating element may be disposed between the first manifold 11 and the second manifold 12, and may prevent heat exchange between the two manifolds and the formation of a heat bridge, which would affect the heat exchange effect of the heat exchanger. The first manifold 11 and the second manifold 12 may be two separate manifolds, but could also be a first manifold 11 and a second manifold 12 formed from one tube by means of a longitudinal partition plate. The longitudinal partition plate may be two partition plates; the two partition plates may be integral with pipe walls of the pipes, but could also be separate.
As shown in
The heat exchanger according to an embodiment of the present invention may be used in the fields of heating, ventilating and air conditioning, motor vehicles, refrigeration and transport, and may be a micro-channel heat exchanger or a parallel-flow heat exchanger, etc. The heat exchanger according to an embodiment of the present invention can reduce costs, increase the wind field uniformity and output wind temperature uniformity of a micro-channel heat pump evaporator, and increase the utilization rate of the heat exchange area.
Moreover, in the heat exchanger according to the present invention, a partition plate may be disposed in the manifold, so as to form different circuits. In addition, in the heat exchanger according to the present invention, the circuit length may be adjusted as required (with the heat exchange tube being bent a number of times). When the heat exchanger is used in an evaporator, the difference between the condensate water produced by the top portion and condensate water of the bottom-half portion is not large, the wind field of the heat exchanger is more uniform, and the output wind temperatures of various parts of the heat exchanger are more uniform.
Furthermore, in the heat exchanger according to the present invention, the manifolds are arranged at a single side, so connecting pipelines and manifolds are saved, and costs are lower. In addition, a single row of flat tubes may be employed, so that wind resistance is low.
