Embodiment Construction

[0029] Unless otherwise specified, the terms used in the context of the present invention have the meanings given below. Other terms not specifically given herein have their usual meanings in the art.

[0030] Figure 1 to Figure 3 shows the structure of the heat exchanger according to the embodiment of the present invention, such as Figure 1 to Figure 3 As shown, the heat exchanger includes a gas-liquid separator arranged in the inner cavity 16 of the heat exchanger, and the gas-liquid separator includes: a bottom plate 3, a liquid baffle 5 and an end plate 7, and the end plate 7 is located at the side of the gas-liquid separator ends. The bottom plate 3 , the liquid baffle plate 5 and the end plate 7 can be steel plates, which are welded on the upper part of the inner cavity 16 of the heat exchanger.

[0031] Such as Figure 4 and Figure 5 As shown, the bottom plate 3 is a plate body with a concave cross section (that is, a curved plate shape). In the figure, the bott...

Abstract

The invention provides a heat exchanger which comprises a gas-liquid separator. The gas-liquid separator comprises a bottom plate, a liquid stop plate and end plates; the bottom plate forms a gas-liquid separation cavity together with the top wall of the heat exchanger; the top wall of the heat exchanger is provided with a heat exchanger air outlet; the bottom plate comprises a cover plate and a guide plate which is connected below the cover plate; the cover plate is provided with a gas-liquid two-phase refrigerant outlet; the gas-liquid two-phase refrigerant outlet is arranged below a gas-liquid two-phase refrigerant inlet to communicate the gas-liquid separation cavity with a heat exchanger inner cavity arranged below the gas-liquid separation cavity; the liquid stop plate is in the shape of a groove, is fastened on the cover plate and arranged in the gas-liquid separation cavity and covers the gas-liquid two-phase refrigerant inlet; the downward side of the liquid stop plate is provided with a liquid stop plate outlet; and the end plates seal two ends of the gas-liquid separation cavity. Due to two times of interception, the liquid refrigerant is separated effectively, and the risk of liquid strike is reduced effectively. An evaporator has a simple internal structure, and the heat exchanger is convenient to manufacture and install.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a heat exchanger, in particular to a heat exchanger with a gas-liquid separator. Background technique [0002] For the air conditioning system, the evaporator is one of the four major components and an indispensable part. It is directly connected to the compressor. If the design of the evaporator is unreasonable, the heat exchange effect is not ideal, and the refrigerant cannot be completely evaporated into a gaseous state. There will be a situation where liquid refrigerant enters the compressor, forming a liquid hammer phenomenon, causing damage to the compressor, and at the same time adversely affecting the normal operation of the air conditioning system. Therefore, how to reasonably design the structure of the evaporator to effectively avoid the liquid hammer phenomenon of the compressor while ensuring the heat exchange effect has become a common and important problem in the desig...
