Shell and tube heat exchanger and air conditioner with same

Abstract

The invention provides a shell and tube heat exchanger and an air conditioner with the same. The shell and tube heat exchanger comprises a cylinder body (10), a liquid equalizing plate (20), an end cover (11) and a flow equalizing structure, wherein the liquid equalizing plate (20) is arranged in the cylinder body (10), the end cover (11) is arranged at a first end of the cylinder body (10), a refrigerant inlet is formed in the end cover (11), a flow equalizing space is formed between the end cover (11) and the liquid equalizing plate (20), the flow equalizing structure is used for circumferentially equalizing a refrigerant entering the flow equalizing space, the flow equalizing structure is arranged corresponding to the refrigerant inlet, and at least one part of the flow equalizing structure is located in the flow equalizing space. According to the shell and tube heat exchanger provided by the invention, the flow equalizing structure is used for circumferentially equalizing the refrigerant entering the flow equalizing space, the refrigerant is enabled to be uniformly distributed in all positions of the liquid equalizing plate, and the refrigerant is further enabled to uniformly enter a heat exchange tube, so the refrigerant is enabled to be completely evaporated, the heat exchange efficiency of the shell and tube heat exchanger is effectively ensured, and the problems of incomplete evaporation of the refrigerant and low heat exchange efficiency due to non-uniform distribution of the refrigerant can be solved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a shell-and-tube heat exchanger and an air conditioner having the same. Background technique [0002] At present, in the medium and low temperature refrigeration industry, dry evaporators are widely used in various refrigeration units due to their good oil return performance. For a dry evaporator with a large cylinder and a large number of heat exchange tubes, the effective uniform distribution of the liquid refrigerant is an important factor affecting the heat exchange efficiency. Unfavorable situations such as the thermal area cannot be fully utilized. The current equalizing structure of the existing dry evaporator is generally a liquid equalizing plate, but when the diameter of the evaporator cylinder is too large, only the liquid equalizing plate is used for liquid separation, and the separation effect will be reduced, and the liquid equalizing effect is not good, resu...
