A heat exchanger capable of improving air circulation

Abstract

The invention discloses a heat exchanger capable of improving the air circulation effect, which belongs to the technical field of air circulation, and comprises a heat exchanger casing and a refrigerant circulation pipe installed on the heat exchanger casing. The cold assembly, and the positions corresponding to the pre-cooling assembly on the side end surface of the heat exchanger shell are respectively fixedly connected with a first condensation assembly and a second condensation assembly, and a discharge assembly is arranged between the second condensation assembly and the first condensation assembly . In the present invention, the moisture content in the air is reduced by using the negative pressure and the low-temperature air through the designed first condensation component, thereby further reducing the probability of frosting during the flow of the air inside the heat exchanger casing , when the first piston seat moves to the highest point, it moves downward, and as the pressure under the first piston seat increases, the third one-way valve will open automatically, and then the condensed low-temperature air can be introduced into the heat exchange inside the machine casing.

Description

technical field [0001] The invention belongs to the technical field of air circulation, and in particular relates to a heat exchanger capable of improving the effect of air circulation. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in industrial production in chemical, petroleum, power, food and other fields. They can be used as heaters, condensers, evaporators, etc. in production, and are widely used. At present, existing heat exchangers are used in During use, the heating efficiency of the heat exchanger is low in a low-temperature environment and the heat exchanger is prone to frost in the heating mode. It is necessary to switch from the heating mode to the defrosting mode and defrost in time. During the defrosting period, the indoor heating will stop. Therefore, at this stage, there is an urgent need for a heat exchanger tha...

Problems solved by technology

[0003] The purpose of the present invention is: in order to solve the problem that the heating efficiency of the heat exchanger is low in the low temperature environment and the heat exchanger in the heating mode is easy to frost during the use of the existing heat exchanger, it is necessary to switch from the heating mode to the defrosting mode. Frost mode, defrosting in time, the indoor heating will stop during the defrosting period, resulting in the problem of lowering the indoor temperature and generating condensed water, and a heat exchanger that can improve the air circulation effect is proposed
