Abstract

PURPOSE:To detect the temperature of a body the temperature of which is to be detected with high accuracy with a small number of components and small number of work processes by holding and fixing a temperature sensor by holding member of excellent thermal conductivity that is fixed to the body. CONSTITUTION:A piping 1 through which a refrigerant, etc., flows has a cylindrical holding member 10 that is made of copper, iron, etc., of a large heat conductivity and is attached to the piping 1 by soldering, etc., and inside this holding member 10 a temperature sensor 3 such as a temperature feeling cylinder, etc., is held and fixed in the state of tight contact. The holding member 10 that fixes the temperature sensor 3 and the piping 1 are covered with a heat insulation material 5 that consists of a material such as foamed polysterene, urethane foam, etc. With this constitution special fixing members for installing the temperature sensor are not necessary and it is possible to detect the temperature of the piping 1 with high accuracy.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature sensor mounting device for detecting the temperature of a fluid or the like flowing in a pipe of an air conditioner.

[0002]

2. Description of the Related Art The temperature of a fluid flowing in a pipe is detected by a temperature sensor such as a temperature sensing tube. The temperature sensor 3 is brought into contact with the heat transfer body 2 having good heat conductivity and fixed,
The temperature sensor 3 is connected to the heat transfer body 2 by the clip 4 having good heat conductivity.
The pipe 1 and the temperature sensor 3 are covered with a heat insulating material 5 after being fixed in close contact with.

[0003]

In the above-described conventional temperature sensor mounting device, the clip 4 is required for closely fixing the temperature sensor 3 to the heat transfer body 2, so that the number of parts and the number of mounting steps are increased. Then, there was a problem that the cost increased.

The present invention is intended to provide a mounting device for a temperature sensor which can solve the above problems.

[0005]

In a temperature sensor mounting device of the present invention, a temperature sensor for detecting the temperature of an object to be detected is held by a holding member having good heat conductivity fixed to the object to be detected. It is characterized by being held and fixed.

[0006]

Since the present invention has the above-mentioned structure, the temperature sensor is directly held and fixed by the holding member serving as a heat transfer medium.
In addition, the temperature sensor accurately detects the temperature of the detected object via the holding member.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. 1 is a sectional view of the first embodiment, FIG.
2 is a sectional view taken along the line AA of FIG.

A holding member 10 is fixed by brazing or the like to the pipe 1 through which a fluid such as a refrigerant flows. The holding member 10 has a cylindrical shape, and the temperature sensor 3 such as a temperature-sensitive tube is held and fixed inside the holding member 10 in a close contact state.

The holding member 10 is made of copper having a high heat transfer coefficient.
A material such as iron is used, and the temperature sensor 3 can accurately detect the temperature of the pipe 1 via the holding member 10 serving as the heat transfer medium.

While holding the temperature sensor 3, the holding member 10 and the pipe 1 are covered with a heat insulating material 5 made of a material such as expanded polystyrene or urethane foam.

Thus, in this embodiment, the temperature sensor 3 is directly held and fixed by the holding member 10 serving as a heat transfer medium.
No special fixing parts are required. In addition, the temperature of the pipe 1 is measured by the temperature sensor 3 via the holding member 10 having a large thermal conductivity.
The temperature sensor 3 can accurately detect the temperature of the pipe 1.

A second embodiment of the present invention will be described with reference to FIG. In this embodiment, instead of the cylindrical holding member 10 in the first embodiment, the temperature sensor 3 is held by a cylindrical holding member 10a having an arc of a semicircle or more. There is.

Also in this embodiment, the same operation and effect as those of the first embodiment can be obtained.

In the first and second embodiments, the holding members 10 and 10a have a circular cross section or a circular shape with a part cut away. , Any shape that can hold the temperature sensor,
Appropriate ones other than the above can be adopted according to the outer shape of the temperature sensor.

[0015]

According to the present invention, since the temperature sensor is directly held and fixed to the holding member having good heat conductivity fixed to the object to be detected, the temperature sensor is held via the holding member. The temperature of the object to be detected can be detected with high precision, and the clip for fixing the temperature sensor as in the past is not required, so the number of parts and the number of mounting steps can be reduced, and the cost can be reduced. be able to.
