Description

Technical Field

[0001] This utility model relates to the field of impact test chamber technology, specifically a temperature control device adapted to an ultra-fast thermal shock test chamber. Background Technology

[0002] Thermal shock test chambers, also known as high and low temperature impact testers, are mainly used in industries such as electronic and electrical components, automation parts, communication components, automotive parts, metals, plastics, defense, aerospace, military, electronic chips (ICs), semiconductor ceramics, and polymer materials to test the physical changes of materials under repeated high and low temperatures and the chemical changes or physical damage caused by thermal expansion and contraction. This can confirm the quality of the product. Thermal shock test chambers are divided into two-compartment and three-compartment types. For two-compartment chambers, two compartments generate high and low temperatures respectively. The material being tested is moved to achieve the temperature difference. However, existing devices are located between two compartments. In order to achieve rapid temperature conversion, the test chamber is generally divided into upper and lower parts, one with high temperature and the other with low temperature, so as to switch the test material.

[0003] Chinese utility model patent, authorization announcement number CN220084627U, discloses an ultra-fast thermal shock test chamber that facilitates switching between hot and cold temperatures. The test object is placed in a temperature zone test chamber, and the switching of temperature environments is achieved through the thermal conversion of dry airflow. This rapid switching of hot and cold temperatures in the test area is achieved through a temperature control device that can quickly switch the hot and cold temperatures to the required test temperature, thereby improving the speed of switching between hot and cold temperatures and enhancing the applicability of the device.

[0004] In existing thermal shock test chambers, the high-temperature control device results in slow heat dissipation from the heating wires during heating, leading to slow heating and cooling rates of the material under test and reducing experimental efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a temperature control device adapted to an ultra-fast thermal shock test chamber, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature control device adapted to an ultra-fast thermal shock test chamber, comprising a sleeve, wherein an air inlet pipe is fixedly connected to one side of the top of the sleeve;

[0007] A vertical pipe is fixed on one side of the sleeve, and several ventilation holes are opened on the vertical pipe body located inside the sleeve.

[0008] A support plate is fixed inside the vertical pipe. Multiple air inlets are opened on the plate body, and a heating wire is fixed at the bottom of the support plate.

[0009] A fixing plate is fixed to the bottom of the vertical pipe, and a first air outlet is opened on the plate body that is connected to the vertical pipe.

[0010] Preferably, an insulation pipe is fixed at the bottom of the sleeve, and the insulation pipe extends out of the bottom of the vertical pipe.

[0011] The insulation pipe is located on the outside of the vertical pipe, and a cavity is formed between the insulation pipe and the vertical pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This temperature control device is adapted to an ultra-fast thermal shock test chamber. In use, the material to be tested is placed in the thermal shock test chamber at the bottom of the temperature control device. The controller controls the heating wire to heat the material. Outside air enters the sleeve through the air pump and air inlet pipe, and then enters the vertical pipe through the vent. After the heating wire heats the outside air, it is directly discharged through the first air outlet, thus coming into contact with the material to be tested. Due to the control of the two airflows, ultra-fast cooling and heating of the material to be tested are achieved, improving experimental efficiency. Attached Figure Description

In order to facilitate the connection of the air outlet pipe of an external air pump and to achieve quick connection of the device, an external thread is provided on the top of the air inlet pipe 2.

[0025] A vertical pipe 301 is fixed on one side of the sleeve 1. Several vent holes 304 are provided on the pipe body of the vertical pipe 301 located inside the sleeve 1 in a ring. A support plate 302 is fixed inside the vertical pipe 301, and multiple air inlets 303 are provided on the plate body of the support plate 302.

[0026] A fixing plate 5 is fixed at the bottom end of the vertical pipe 301. The fixing plate 5 has a first air outlet 501 that communicates with the vertical pipe 301. Outside air enters the sleeve 1 through the air inlet pipe 2, and then enters the vertical pipe 301 through the air vent 304. After the heating wire 305 heats the outside air, it is discharged through the first air outlet 501.

[0027] To reduce heat loss, improve heating efficiency, and reduce energy consumption, a heat-insulating pipe 6 made of metal material is fixed at the bottom of the sleeve 1.

The controller controls the heating wire 305 to heat the material. Outside air enters the sleeve 1 through the air pump and air inlet pipe 2, and then enters the vertical pipe 301 through the vent 304. After the heating wire 305 heats the outside air, it is discharged through the first air outlet 501, thereby coming into contact with the material to be tested and achieving ultra-fast heating of the material to be tested.
