Heat exchanger capable of improving air circulation effect

Abstract

The invention discloses a heat exchanger capable of improving the air circulation effect, and belongs to the technical field of air circulation, the heat exchanger comprises a heat exchanger shell and a refrigerant circulation pipe installed on the heat exchanger shell, and a pre-cooling assembly is arranged on the refrigerant circulation pipe; a first condensation assembly and a second condensation assembly are fixedly connected to the positions, corresponding to the pre-cooling assembly, of the side end face of the heat exchanger shell, and a discharging assembly is arranged between the second condensation assembly and the first condensation assembly. According to the heat exchanger, through the designed first condensation assembly, the combined action of negative pressure and low-temperature air is utilized, the moisture content in the air is reduced, and therefore the probability that the air frosts in the flowing process in the heat exchanger shell can be further reduced, when the first piston seat moves to the highest point, the first piston seat moves downwards, and the first piston seat moves downwards; and along with the increase of the pressure below the first piston seat, the third one-way valve can be automatically opened, so that the condensed low-temperature air can be introduced into the shell of the heat exchanger.

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
