Embodiment Construction

[0023] The present invention proposes a constant temperature box structure, specific reference Figure 1 to Figure 6 , The structure of the constant temperature box includes: a constant temperature cavity 100 , a temperature sensor 200 , and a temperature adjustment device 300 .

[0024] The constant temperature chamber 100 includes a cover body 120 and a drawer slot 140 , wherein the cover body 120 can accommodate the drawer slot 140 . Specifically, the cover body 120 accommodates the drawer groove 140 to form a drawer structure, and the inner space of the drawer structure serves as a constant temperature place for placing the device under test.

[0025] The temperature sensor 200 is connected with the constant temperature cavity 100 and is used for detecting the temperature in the constant temperature cavity 100 . Specifically, the temperature sensor 200 may be a non-contact or contact sensor, preferably a contact sensor, such as a thermocouple sensor, a PN junction tempera...

Abstract

The invention relates to a constant temperature cabinet. The constant temperature cabinet comprises a constant temperature cavity, a temperature senor and a temperature regulating device, wherein the constant temperature cavity comprises a cover body and a drawer groove, and the cover body is used for accommodating the drawer groove; the temperature sensor is connected with the constant temperature cavity and used for detecting the temperature inside the constant temperature cavity; the temperature regulating device is connected with the constant temperature cavity and used for regulating the temperature inside the constant temperature cavity. The constant temperature cabinet adopts a drawer type structure, an opening of a box body is arranged in a side face with small area, and the heat rising to the top of the sealed box body also can be prevented from overflowing, so that the good constant temperature effect can be achieved.

Description

technical field [0001] The invention relates to the field of experimental instruments, in particular to a constant temperature box and a temperature measuring system. Background technique [0002] When testing the thermal resistance and thermal structure function of a semiconductor device, the semiconductor device needs to be placed in a constant temperature environment, usually in a constant temperature box. The incubator is a box or cabinet whose outer wall is equipped with heat-insulating materials. By thermally isolating it from the outside world, the temperature of the space inside the box can be kept constant. Thermostats are widely used today in laboratories, industry and medicine. The mechanical mechanism of the traditional incubator is relatively complicated, using many parts, and the heat conduction area with the outside is large, so it cannot achieve a good constant temperature effect. Contents of the invention [0003] Based on this, it is necessary to provid...
