Central air conditioner heat exchanger

Abstract

The invention discloses a central air conditioner heat exchanger. The central air conditioner heat exchanger comprises a tank body, a first liquid inlet is fixedly formed in one side position of the upper end of the outer surface of the tank body, a first liquid outlet is fixedly formed in one side position of the lower end of the outer surface of the tank body, a second liquid outlet is fixedly formed in the position, close to the first liquid inlet position, of the upper end of the outer surface of the tank body, and a second liquid inlet is fixedly formed in the position, close to the first liquid outlet position, of the lower end of the outer surface of the tank body. According to the central air conditioner heat exchanger, when a filter screen is blocked or not smooth, the pressure intensity inside the heat exchanger is too large, liquid in the heat exchanger pushes a filter screen belt to move downwards, drives a control rod to move downwards, finally pushes a first electrode plate to make contact with a second electrode plate, finally a circuit of a buzzer is enabled to be closed to form a circuit, the buzzer gives out an alarm sound, air conditioner maintenance personnel are reminded that a pipeline in the heat exchanger is blocked or unsmooth, and the air conditioner maintenance personnel maintain the heat exchanger in time.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a central air-conditioning heat exchanger. Background technique [0002] The heat exchanger is a core component in the air conditioner, and it is especially important for the cooling and heating of the air conditioner. The heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid, also known as a heat exchanger. The heat exchanger is used in chemical, Petroleum, power, food and many other industrial productions occupy an important position. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. [0003] A Chinese patent discloses a shell-and-tube heat exchanger, the patent application number is CN202011356865.3, the shell-and-tube heat exchanger includes a heat exchanger shell, and a tube-side assembly arranged in the inner cavity of the heat exchanger s...

Problems solved by technology

[0004] The above comparative patents have improved the installation and connection of the heat exchanger, but after the heat exchanger has been used for a period of time, the impurities in the exchange liquid will adhere to the inner wall of the pipe, and some of the impurities attached to the exchange liquid will Falling off, as the exchange liquid enters other equipment of the air conditioner, it will affect the normal operation of other equipment. During the air conditioner, it will take a lot of time for maintenance workers to check whether it is because there are too many impurities in the heat exchanger, which causes the heat exchange effect of the air conditioner to deteriorate.
