Description

Technical Field

[0002] A constant temperature and humidity test chamber is a device used to simulate various temperature and humidity environmental conditions, mainly for testing the tolerance and performance changes of materials and products under specific temperature and humidity conditions. It is widely used in industries such as electronics, electrical appliances, automobiles, aerospace, materials, chemical engineering, textiles, and pharmaceuticals to ensure the reliability and stability of products in different environments. A constant temperature and humidity test chamber consists of a housing, a refrigeration system, a heating system, a humidification system, a dehumidification system, an air circulation system, and a control system. The refrigeration system usually uses compression refrigeration to simulate a low-temperature environment by reducing the temperature inside the test chamber. The efficiency and performance of the refrigeration system directly affect the temperature control accuracy of the device. The heating system mainly provides heat through electric heaters to raise the temperature inside the chamber to the set value. The heaters usually work in cooperation with temperature sensors to achieve precise temperature control. The humidifier usually uses steam or ultrasonic humidification, and the dehumidification system mostly relies on refrigeration technology to reduce the moisture content in the air and control the humidity inside the chamber. The air circulation system ensures uniform distribution of temperature and humidity inside the chamber through fans and air diversion designs, ensuring the consistency of the environment where each test sample is located. Modern constant temperature and humidity test chambers usually cooperate with PLCs and human-machine interfaces, allowing precise setting of temperature and humidity conditions, monitoring of the device operation status, recording, and exporting of test data.

[0003] The air circulation inside the existing constant temperature and humidity test chamber mainly guides the air flow through its housing structure to evenly distribute the heated, cooled, humidified, or dehumidified air to the working area of the test chamber, ensuring that test samples set at different positions in the test chamber can all be tested under the same environmental conditions.

[0032] Please refer to Figures 1 to 5The utility model discloses a constant temperature and humidity test chamber shell structure, which includes a working box 100, a first installation box 200 and a second installation box 300. The working box 100 is arranged on the top side of the first installation box 200, and the second installation box 300 is arranged on the adjacent sides of the box and the first installation box 200. Therefore, the working box 100, the first installation box 200 and the second installation box 300 are stacked and connected to form an integral shell structure of the constant temperature and humidity test chamber. The first installation box 200 and the second installation box 300 are used for installing various functional modules of the constant temperature and humidity test chamber, and the working box 100 is used for performing constant temperature and humidity tests on items to be tested. Specifically, the working box 100 includes an inner liner structure 110 and an outer shell structure 120. The outer shell structure 120 is arranged on the top of the first installation box 200. The inner liner structure 110 and the outer shell structure 120 correspond to each other, and the inner liner structure 110 is embedded and installed inside the outer shell structure 120. The inner liner structure 110 is used to perform a constant temperature and humidity test on the object to be tested, and the outer shell structure 120 is used to isolate the inner liner structure 110 from the external environment, reduce the heat exchange between the inner liner structure 110 and the external environment, so as to ensure that the temperature inside the inner liner structure 110 is constant. Among them, the inner tank structure 110 is provided with a working cavity a, a ventilation cavity b and a temperature control cavity c, the working cavity a is connected with the ventilation cavity b and the temperature control cavity c respectively; the ventilation cavity b and the temperature control cavity c are both arranged on the adjacent sides of the working cavity a; the ventilation cavity b is connected to the temperature control cavity c with its back to the working cavity a; the side wall of the temperature control cavity c facing the second installation box 300 is connected to the outer shell structure 120, and then connected to the second installation box 300 through the outer shell structure 120. In one embodiment, the ventilation cavity b is arranged on the top side of the temperature adjustment cavity c and is connected through the first ventilation hole d, and the ventilation cavity b is connected to the top side of the working cavity a through the second ventilation hole e, wherein the first ventilation hole d is installed with a fan, and the temperature adjustment cavity c is connected to the bottom side of the working cavity a. Therefore, when the constant temperature and humidity test chamber is actually working, under the drive of the fan, the temperature adjustment cavity c, the working cavity a and the ventilation cavity b form an air flow loop, so that the hot air input from the second installation cavity to the temperature adjustment cavity c first enters the working cavity a to heat the internal gas environment of the liner, and then the hot air flow is input to the ventilation cavity b through the second ventilation hole e, and then flows back to the temperature adjustment cavity c through the first ventilation hole d. Under the action of the hot air reflux at a preset temperature, the gas environment temperature inside the working cavity a can be adjusted to a preset temperature value, and the temperature inside the working cavity a can be effectively maintained constant, thereby greatly improving the accuracy and stability of the constant temperature of the constant temperature and humidity test chamber, thereby reducing the test error and improving the accuracy of the test results of the constant temperature and humidity test chamber.

[0033] Further, the inner liner structure 110 includes a first partition 111 and a second partition 112. The first partition 111 is disposed between the working cavity a, the ventilation cavity b, and the temperature control cavity c. And one end of the first partition 111 is connected to the inner surface of the top wall of the inner liner structure 110, and the other end of the first partition 111 extends a preset distance toward the bottom wall of the inner liner structure 110. Thus, the gap between the end of the first partition 111 and the bottom wall of the inner liner structure 110 forms an air flow channel between the working cavity a and the temperature control cavity c. The second partition 112 is disposed between the ventilation cavity b and the temperature control cavity c, thereby separating the ventilation cavity b and the temperature control cavity c into two independent spaces on both sides. Furthermore, the first partition 111 combined with the second partition 112 can guide the air flow direction inside the inner liner structure 110 to achieve full circulation of hot air inside the inner liner structure 110. Specifically, the second ventilation hole e is disposed on the first partition 111, so that the working cavity a communicates with the ventilation cavity b. The first ventilation hole d is disposed on the second partition 112, so that the ventilation cavity b communicates with the temperature control cavity c, thereby ensuring the hot air fluidity inside the inner liner structure 110.

[0034] Further, the working box 100 further includes a blower housing 140. The blower 130 is disposed outside one side wall of the temperature control cavity c, and one end of the blower 130 communicates with the outside of the working box 100 through the housing structure 120. The blower housing 140 is correspondingly disposed inside the side wall of the temperature control cavity c with respect to the blower 130, and one end of the blower housing 140 is cooperatively connected to the blower 130, and the other end of the blower housing 140 communicates with the first ventilation hole d. The blower 130 exchanges heat with the external environment through the housing structure 120, so as to ensure that the blower 130 has sufficient heat dissipation efficiency for cooling, so as to ensure the normal operation of the blower 130. Driven by the blower 130, the hot air flow generated in the temperature control cavity c sequentially passes through the working cavity a, the second ventilation hole e, the ventilation cavity b, and the first ventilation hole d to form a hot air flow circulation and return, thereby ensuring that the temperature inside the working cavity a can quickly and evenly rise to a constant temperature value.

[0035] Further, the working box 100 further includes a drying cylinder 150. The drying cylinder 150 is disposed on the surface of one side wall of the working cavity a, and one end of the drying cylinder 150 facing away from the working cavity a extends to the outside of the working box 100 through the housing structure 120. Thus, the drying cylinder 150 can absorb the moisture inside the working cavity a, thereby ensuring that a low humidity environment can be maintained inside the working cavity a.

[0036] Further, the second installation box body 300 includes a heating unit 310. The heating unit 310 is disposed on the inner side of the side wall of the second installation box body 300 corresponding to the temperature adjustment cavity c, and the output end of the heating unit 310 extends into the temperature adjustment cavity c through the housing structure 120. Thus, the output end of the heating unit 310 can heat and raise the temperature of the air inside the temperature adjustment cavity c to form a hot air flow at a preset temperature. Then, driven by the fan 130, the hot air flow sequentially passes through the temperature adjustment cavity c, the working cavity a, and the ventilation cavity b to circulate and adjust the temperature of the inner tank gas environment.

[0037] Further, the working box body 100 includes a door body 160. The door body 160 is disposed on one side of the working box body 100, and the door body 160 is sequentially connected to the housing structure 120 and the inner tank structure 110 in a matching manner. Specifically, the door body 160 is provided with an inner door cover 161. Among them, the door body 160 is connected to the housing structure 120 in a matching manner, and the inner door cover 161 is connected to the inner tank structure 110 in a matching manner. In one embodiment, both the housing structure 120 and the inner tank structure 110 are provided with door frames, and the door frames of the housing structure 120 and the door frames of the inner tank structure 110 are sequentially nested and respectively matched with the door body 160 and the inner door cover 161, so that a relatively closed working space can be formed inside the inner tank to maintain the constant temperature and humidity performance of the inner tank structure 110.

[0038] Further, the constant temperature and humidity test chamber housing structure further includes a moving component 400. The moving component 400 is disposed at the bottom of the first installation box body 200 and the second installation box body 300. Thus, the constant temperature and humidity test chamber housing structure can be movably arranged through the moving component 400 to improve the convenience of use of the constant temperature and humidity test chamber housing structure. Specifically, the moving component 400 includes a support plate 410 and a plurality of moving wheels 420. The top side surface of the support plate 410 is connected to the bottom side surface of the first installation box and the bottom side surface of the second installation box; the plurality of moving wheels 420 are respectively disposed on the bottom side surface of the support plate 410. Thus, the support plate 410 can support the entire constant temperature and humidity test chamber housing structure, and the entire constant temperature and humidity test chamber housing structure can be movable through the plurality of moving wheels 420.

[0039] In summary, the housing structure of the constant temperature and humidity test chamber disclosed by the present utility model forms the overall housing structure of the constant temperature and humidity test chamber through the stacked connection of the working chamber, the first installation chamber, and the second installation chamber. The inner liner structure is fitted and installed inside the outer shell structure. The inner liner structure is used for conducting the constant temperature and humidity test of the article to be tested, while the outer shell structure is used for isolating the inner liner structure from the external environment, reducing the heat exchange between the inner liner structure and the external environment, so as to ensure the constant temperature inside the inner liner structure. When the constant temperature and humidity test chamber is actually working, driven by the fan, the temperature control chamber, the working chamber, and the ventilation chamber form an air flow loop, so that the hot air input from the second installation chamber to the temperature control chamber first enters the working chamber to heat up the gas environment inside the inner liner. Subsequently, the hot air flow enters the ventilation chamber through the second ventilation hole and then returns to the temperature control chamber through the first ventilation hole. Under the action of the hot air reflux at the preset temperature, the temperature of the gas environment inside the working chamber can be adjusted to the preset temperature value, and the temperature inside the working chamber can be effectively maintained constant, thus greatly improving the accuracy and stability of the constant temperature of the constant temperature and humidity test chamber, further reducing the test error and improving the accuracy of the test results of the constant temperature and humidity test chamber. Moreover, by reducing the complexity of the air guiding structure inside the inner liner structure, the absorption and transmission of the heating capacity by the inner liner structure can be effectively avoided, thereby reducing the loss of heating capacity and improving the energy utilization rate.

For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
