Embodiment Construction

[0026] The following description and the accompanying drawings sufficiently illustrate specific embodiments herein to enable those skilled in the art to practice them. Portions and features of some embodiments may be included in or substituted for those of other embodiments. The scope of the embodiments herein includes the full scope of the claims, and all available equivalents of the claims. Herein, the terms "first", "second", etc. are only used to distinguish one element from another element without requiring or implying any actual relationship or order between these elements. In fact the first element can also be called the second element and vice versa. Furthermore, the terms "comprising", "comprising" or any other variation thereof are intended to cover a non-exclusive inclusion such that a structure, means or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed elements, or also elements inherent in th...

Abstract

The invention belongs to the technical field of heat exchangers, and discloses a heat exchanger and an air conditioner. The heat exchanger comprises a heat exchange tube group, a supercooling tube group, a supercooling bypass tube, a dividing bypass tube, a supercooling check valve and a dividing check valve, wherein the supercooling tube group is connected to the heat exchange tube group in series; a flow path being of a pulsed arrangement structure is formed by the supercooling tube group and the heat exchange tube group; the supercooling bypass tube and the supercooling tube group are arranged in parallel; the supercooling check valve is arranged on the supercooling bypass tube; and the dividing check valve is arranged on the dividing bypass tube. The heat exchanger has the beneficial effects that when the heat exchanger operates for heating, the heat of the heat exchanger is divided through the check valves; the complexity of the system can be reduced; the pressure loss of the system caused when the heat passes through the supercooling tube group during heating is reduced, and thus, the heat exchange efficiency of the system is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchanger and an air conditioner. Background technique [0002] If the existing heat exchanger needs to divide the flow, it usually uses a shunt tube or a flow divider to divide the flow. However, the conventional shunt method has no direction distinction. It passes through the same pipeline during the cooling operation and the heating operation. When the device is in cooling operation, it passes through the subcooling pipeline to meet the cooling operation requirements, while in heating operation, it still passes through the subcooling pipeline, which will increase the system pressure loss and reduce the heat exchange efficiency of the system. Contents of the invention [0003] Embodiments of the present invention provide a heat exchanger and an air conditioner to solve the problem that the heat exchange efficiency of the heat exchanger decreases during heating ...
