Positioning device for defrosting temperature sensing head of heat exchanger

Abstract

The invention discloses a positioning device for a defrosting temperature sensing head of a heat exchanger. The positioning device comprises a temperature sensing head chuck for containing the temperature sensing head, a heat exchanger pipe clamp for clamping a heat exchanger pipeline, and a connecting strip. The temperature sensing head chuck and the heat exchanger pipe clamp are connected through the connecting strip. The heat exchanger pipe clamp is provided with an elastic containing cavity, and the elastic containing cavity is provided with an opening with a guide arm. According to the positioning device for the temperature sensing head, the temperature sensing head is isolated from an aluminum pipe of an evaporator, the temperature sensing head can truly reflect the temperature of a frost layer around the evaporator, a refrigerator can be made to quit a defrosting mode more accurately, and high-efficiency operation of the refrigerator is ensured.

Description

technical field [0001] The invention relates to the technical field of refrigerator control, and more specifically relates to a positioning device for a defrosting temperature sensing head of a heat exchanger of an air-cooled refrigerator. Background technique [0002] The temperature sensor (temperature sensor) is a sensor that can sense temperature and convert it into a usable output signal. It has a high temperature coefficient and is highly sensitive to temperature. Thermal resistance temperature sensors are commonly used in refrigerators and air conditioners to measure temperature. When the ambient temperature changes, the resistivity of the thermal resistance temperature sensor also changes, and the controller can calculate the corresponding temperature according to its voltage drop. The air-cooled refrigerator is a common type of refrigerator, and its biggest advantage is that it is frost-free. Keep your refrigeration system running efficiently by defrosting your re...
