Description

Technical Field

[0001] This utility model relates to the field of temperature shock test chamber technology, and in particular to a temperature shock test chamber. Background Technology

[0002] A temperature shock test chamber is an experimental device used to test the resistance and stability of materials, components, and products under rapid temperature changes. By rapidly switching between high and low temperatures, the temperature shock test chamber simulates the extreme environmental changes that a product may experience, thereby assessing its reliability and service life. This test is particularly important for electronic components, automotive parts, aerospace products, and other equipment that needs to operate in harsh environments. Temperature shock test chambers are typically configured with two or more temperature zones: a high-temperature zone and a low-temperature zone. During the test, the sample moves rapidly between the two or more temperature zones to simulate extreme temperature changes. Existing two-chamber temperature shock test chambers have two independent high-temperature and low-temperature zones, and the sample is rapidly switched between the two zones via a mechanical lifting or sliding device. This design ensures a fast temperature transition, typically completed within seconds.

[0003] Chinese patent application CN201310300469.2 discloses a high and low temperature impact test chamber, which includes a high-temperature chamber, a low-temperature chamber, an electrical cabinet, an electrical system, a refrigeration system, and a heating system. The high-temperature chamber houses the heating system, and the low-temperature chamber houses the refrigeration system. The heating and refrigeration systems are respectively connected to the electrical system. The high-temperature chamber contains a high-temperature bath air conditioning system, and the low-temperature chamber contains a low-temperature bath circulation system. The high-temperature bath air conditioning system and the low-temperature bath circulation system are respectively connected to the electrical system. The high-temperature chamber and the low-temperature chamber each contain a vertically movable basket transmission system. However, the high-temperature and low-temperature chambers of the aforementioned high and low temperature impact test chamber are made of sheet metal, and the electrical cabinet is an integral structure with both chambers. This results in poor replaceability during maintenance, significantly increasing the difficulty and cost of maintenance and repair. Utility Model Content

[0031] See also Figures 1 to 3 This utility model discloses a temperature shock test chamber 10, which includes a chamber body 100, a first test chamber 200 and a second test chamber 300. In this embodiment, the first test chamber 200 is configured as a low temperature test chamber and the second test chamber 300 is configured as a high temperature test chamber. Both the first test chamber 200 and the second test chamber 300 are disposed inside the chamber body 100. The first test chamber 200 is disposed at the top of the chamber body 100 and the second test chamber 300 is disposed at the bottom of the chamber body 100. The bottom wall of the first test chamber 200 is connected to the top wall of the second test chamber 300 through a conveying channel a. The temperature shock test chamber 10 also includes a material support mechanism 400 and a drive unit 500. The material support mechanism 400 can be connected to the inside of the first test chamber 200 and the inside of the second test chamber 300, and can also be connected to the conveying channel a. The drive unit 500 is located at the top of the first test chamber 200, and the output end of the drive unit 500 drives the material support mechanism 400. Thus, the drive unit 500 can drive the material support mechanism 400 to reciprocate up and down in the first test chamber 200 and the second test chamber 300 through the conveying channel a. Specifically, the housing 100 includes a first mounting cavity 110 and a second mounting cavity 120. The first mounting cavity 110 is located at the top of the housing 100, and the second mounting cavity 120 is located at the bottom of the housing 100.

This allows the first test cavity 200 and the second test cavity 300 to be installed and disassembled according to actual operation, maintenance, and repair conditions, greatly enhancing the ease of use of the temperature shock test chamber 10 of this utility model. The modular design described above improves the targeting of equipment maintenance and parts replacement, significantly reduces the cost of equipment use and maintenance, and effectively extends the service life of the equipment.

[0032] Furthermore, the bottom wall of the first test chamber 200 is provided with a first mating hole b, and the conveying channel a is provided through the bottom wall of the first test chamber 200 corresponding to the first mating hole b; correspondingly, the top wall of the second test chamber 300 is provided with a second mating hole c, and the conveying channel a is provided through the top wall of the second test chamber 300. Thus, the material support mechanism 400 can reciprocate up and down between the first test chamber 200 and the second test chamber 300 through the first mating hole b, the conveying channel a, and the second mating hole c.

[0033] Furthermore, the material support mechanism 400 includes a material support plate assembly, several support columns 420, a first sealing plate 430, and a second sealing plate 440. The first sealing plate 430, the material support plate assembly, and the second sealing plate 440 are arranged sequentially. The several support columns 420 are respectively disposed on the side edges of the material support plate assembly, and each support column 420 is sequentially connected to the first sealing plate 430, the material support plate assembly, and the second sealing plate 440.

Specifically, the first sealing plate 430 is disposed in the first test chamber 200. When the material support plate assembly descends to the second test chamber 300, the first sealing plate 430 engages with the first mating hole b, thereby ensuring the sealing of the first test chamber 200 and preventing the gas at the preset temperature in the first test chamber 200 from entering the second test chamber 300 and affecting the temperature of the second test chamber 300. The second sealing plate 440 is disposed in the second test chamber 300. When the material support plate assembly rises to the first test chamber 200, the second sealing plate 440 engages with the second mating hole c, thereby ensuring the sealing of the second test chamber 300 and preventing the gas at the preset temperature in the second test chamber 300 from entering the first test chamber 200 and affecting the temperature of the first test chamber 200.

[0034] Furthermore, the sidewalls of the first test chamber 200 are provided with a plurality of first slide rails 210 corresponding to the plurality of support columns 420, and simultaneously, the sidewalls of the second test chamber 300 are provided with a plurality of second slide rails 310 corresponding to the plurality of support columns 420. Specifically, each support column 420 can be slidably connected to the corresponding first slide rail 210 and the corresponding second slide rail 310, thereby enabling the material support mechanism 400 to move up and down along the plurality of first slide rails 210 and the plurality of second slide rails 310, thus ensuring the lifting stability of the material support mechanism 400.

[0035] Furthermore, a connecting part 431 is provided on the top side surface of the first sealing plate 430. The connecting part 431 can be connected to the output end of the drive unit 500, so that the drive unit 500 can drive the material support mechanism 400 to perform lifting and lowering movements through the connecting part 431.

[0036] Furthermore, the support plate assembly comprises two stacked support plates 410, with several support columns 420 connected to the side edges of each support plate 410. Specifically, each support plate 410 is provided with several through holes d to increase the contact area between the sample and the ambient air, thereby improving the uniformity of sample heating and cooling.

[0037] In summary, the temperature shock test chamber disclosed in this utility model provides installation space for the first test chamber and the second test chamber by dividing the chamber body into a first installation cavity and a second installation cavity, respectively. The first installation cavity is located at the top of the chamber body, and the second installation cavity is located at the bottom of the chamber body. The first test chamber is detachably fitted into the first installation cavity, and the second test chamber is detachably fitted into the second installation cavity.
