Description

Technical Field

[0001] The utility model relates to the technical field of test boxes, and more specifically to a high-temperature test box with double boxes and independent control. Background Art

[0002] High temperature test chamber is one of the quality testing equipment for industrial products and materials. Its working principle is mainly to detect the performance of products or materials by controlling temperature and air humidity. High temperature test chamber is suitable for the adaptability test of electrical, electronic, instrumentation and other products, parts and materials during storage, transportation and use under high temperature and hot and humid alternating environment; it is a reliability test equipment for various electronic, electrical, electrical, plastic and other raw materials and devices to conduct heat resistance, moisture resistance, dryness resistance test and quality control engineering, especially suitable for high temperature resistance and hot and humid cycle test of products such as optical fiber, LED, crystal, inductor, PCB, battery, computer, mobile phone, etc.

[0003] Traditional single high temperature test chambers occupy a large area. When multiple products need to be tested at the same time, multiple high temperature test chambers need to be purchased, which further increases the floor space and increases the space requirements. This not only increases the cost of use, but also may limit the scale and efficiency of the test in an environment with limited space. Secondly, when multiple high temperature test chambers are used together, wiring becomes a complex problem. In traditional single high temperature test chambers, each test chamber has its own independent control system and circuit. Each test chamber needs to be connected to power supply, sensor, control circuit, etc. When multiple test chambers work at the same time, various circuits are intertwined, which is easy to cause confusion and errors. This not only increases the difficulty and pressure of the operator's work, but also increases the risk of equipment failure or safety accidents caused by incorrect wiring. Therefore, operators need to have professional electrical knowledge to ensure the correct connection of various sensors, power supplies, control circuits, etc. In addition, the wiring and management of multiple high temperature test chambers also increase the difficulty of maintenance and troubleshooting.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0024] See also Figure 1 to Figure 3 As shown, the embodiment of the utility model provides a double-box independently controlled high-temperature test box, including a first test box 1, a second test box 2 and a power distribution cabinet 3. The first test box 1, the second test box 2 and the power distribution cabinet 3 are connected in sequence and arranged side by side. The first test box 1 and the second test box 2 are both provided with a drive component 41 and a heater 42. The power distribution cabinet 3 is provided with a controller 31. The drive component 41 and the heater 42 are both electrically connected to the controller 31. This design not only reduces the floor space, but also makes the layout of the equipment more compact. The first test box 1 and the second test box 2 are controlled by the same power distribution cabinet 3, which simplifies the connection and wiring work between the first test box 1 and the second test box 2. Secondly, each test box is provided with a drive component 41 and a heater 42. The power distribution cabinet 3 can control the drive component 41 and the heater 42 in each test box to achieve independent control. Each test box can be heated separately as needed, avoiding energy waste.

[0025] The existing test box generally has a heating element installed in the test chamber 521 of the test box, and the air in the test chamber 521 is heated by the heating element. Such a design easily causes the temperature in the test chamber 521 to gradually decrease from the heating element to the surrounding areas, making it difficult to ensure the consistency of the temperature of each area in the test chamber 521, and easily causing large temperature fluctuations in the test chamber 521.

[0026] Based on the above problems, this embodiment also makes the following improvements, specifically:

[0027] The first test box 1 and the second test box 2 both include a first box 51 and a second box 52, the first box 51 and the second box 52 are nested, and a circulating air duct is formed in the gap between the first box 51 and the second box 52, the driving component 41 and the heater 42 are both arranged in the circulating air duct, the second box 52 is hollow inside to form a test chamber 521 for placing samples, and the two opposite side walls of the second box 52 are both provided with vents to connect the test chamber 521 and the circulating air duct. Specifically, the heater 42 is used to heat the air in the circulating air duct, and the driving component 41 drives the air heated by the heater 42 to flow in the circulating air duct and the test chamber 521 of the second box 52, so that the hot air circulates, thereby reducing the temperature fluctuation in the test chamber 521, helping to maintain the temperature stability in the test chamber 521, and avoiding the test error caused by temperature fluctuation; secondly, the circulation of hot air in the test chamber 521 helps to ensure that the temperature of each part in the test chamber 521 is uniform, so as to obtain more accurate and reliable test results.

[0028] Preferably, the driving assembly 41 includes an impeller and a volute, the impeller is arranged in the volute, and the volute is arranged on the inner top surface of the first box body 51. Specifically, the impeller is arranged in the volute, which can effectively drive the air circulation; the volute guides the airflow to flow along a specific path, enhances the fluidity of the air, ensures that the air circulation in the test chamber 521 is smoother and more uniform, reduces the safety hazards caused by air stagnation or vortex, and improves the safety of the operation of the high temperature test box with independent control of the double boxes.

[0029] Preferably, a first exhaust fan 61 and a first circulation fan 62 are disposed on the top of the first test box 1 and the top of the second test box 2. The exhaust duct of the first exhaust fan 61 is connected to the test chamber 521, and the first circulation fan 62 is connected to the impeller.

[0030] Preferably, the front ends of the first test box 1 and the second test box 2 are both provided with double doors 7, and the double doors 7 include a first door 71 and a second door 72, and the first door 71 and the second door 72 are symmetrically arranged. Specifically, the first door 71 and the second door 72 are both provided with an observation window 8 in the shape of a long strip, and the observation window 8 is used to observe the state of the sample in the test chamber 521. The first door 71 and the second door 72 each include an outer door panel, an inner door panel and a door lock, the inner side of the outer door panel is fixedly connected to the inner door panel, the outer side of the outer door panel is provided with a handle, and the door lock is nested on the outer door panel and the inner door panel, and the first test box 1 and the second test box 2 are both connected to the double doors 7 by hinges.

[0031] Preferably, the bottom of the first test box 1 and the bottom of the second test box 2 are both provided with moving wheels 9. Specifically, the moving wheels 9 enable the dual-box independently controlled high-temperature test box to be easily moved on a flat ground, which provides convenience for the user when carrying, moving or rearranging the dual-box independently controlled high-temperature test box, thereby improving work efficiency.
