Problems solved by technology

[0004] However, during the assembly process of the temperature-sensing package assembly, there are phenomena such as dislocation and looseness of the inserts, which cause the temperature-sensing package and the inner surface of the sleeve to not fit tightly, resulting in poor stability of the temperature-sensing package assembly, so that the temperature-sensing package assembly cannot More accurate detection of temperature
[0005] Based on this, there is an urgent need to invent a temperature-sensing package assembly to solve the problems that the temperature-sensing package and the casing are not tightly bonded and the temperature detection accuracy of the temperature-sensing package assembly is poor

Embodiment 1

[0042] Such as figure 1 As shown, this embodiment provides a temperature-sensing package assembly, which includes a sleeve 1, a temperature-sensing package 2, and an insert 3, the insert 3 is fixed to the temperature-sensing package 2, and the insert is fixed as one 3 and the temperature-sensing package 2 are arranged in the casing 1, and the insert 3 makes the temperature-sensing package 2 and the casing 1 relatively fixed. By installing the fixed insert 3 and the temperature-sensing package 2 into the sleeve 1, the phenomenon of misalignment and loosening of the insert 3 can be effectively avoided, so that the temperature-sensing package 2 and the inner surface of the sleeve 1 are tightly bonded , the assembled temperature-sensing package assembly has good stability, which can improve the temperature detection accuracy of the temperature-sensing package assembly. In addition, by putting the fixed insert 3 and the temperature-sensing package 2 into the casing 1, the assembly...

Embodiment 2

[0053] Such as Figure 5 As shown, the structure of the temperature-sensing package assembly provided in this embodiment is roughly the same as the temperature-sensing package assembly provided in Example 1. The main difference between the two is that the cross-section of the temperature-sensing package 2 in this embodiment is a regular hexagon. The shape and size of the abutment line 3111 where the first protrusion 311 abuts against the outer peripheral surface of the temperature-sensitive package 2 matches the shape and size of the outer peripheral surface of the temperature-sensitive package 2, so that the temperature-sensitive package 2 and the insertion piece 3 can be realized The circumferential direction of the temperature sensing package 2 has better contact effect.

Abstract

The invention relates to the technical field of air conditioners, in particular to a sensing bulb assembly, a heat exchanger and an air conditioner. The sensing bulb assembly comprises a sleeve, a sensing bulb and a male tab. The male tab and the sensing bulb are fixed, the male tab and the sensing bulb which are fixed together are arranged in the sleeve, and the sensing bulb and the sleeve are oppositely fixed through the male tab. As the male tab and the sensing bulb which are fixed together are arranged in the sleeve, the phenomena of misplacing and loosening of the male tab can be effectively avoided, the sensing bulb and the inner surface of the sleeve are tightly attached, the assembled sensing bulb assembly has good stability, and the temperature detection precision of the sensing bulb assembly can be improved. In addition, as the male tab and the sensing bulb which are fixed together are arranged in the sleeve, the sensing bulb assembly can be assembled more easily and rapidly.According to the heat exchanger, the phenomenon that the detection superheat degree or supercooling degree of the heat exchanger is not correct can be avoided. According to the air conditioner, it can be guaranteed that overload protection of a compressor of the air conditioner is accurately started and shut down.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a temperature sensing package assembly, a heat exchanger and an air conditioner. Background technique [0002] At present, in the field of air-conditioning heat exchangers, a temperature-sensing package assembly is usually placed at a certain position of the heat exchanger. The temperature-sensing package assembly is used to detect the temperature at the corresponding position of the heat exchanger, and the temperature-sensing package assembly then transmits the detected temperature signal to the Controller, the controller is used to control and adjust the working status of the various components of the air conditioner. [0003] The temperature-sensing package components in the prior art include independent sleeves, temperature-sensing packages and inserts. There is a gap between the temperature-sensing package and the casing. If the temperature-sensing package is direct...
