Description

Technical Field

[0001] The utility model relates to the technical field of environmental simulation equipment, in particular to an environmental test box. Background Art

[0002] Climate simulation test chambers are used to simulate climate conditions, such as temperature and humidity, and are widely used in industries such as electronics, military, plastics, hardware, and chemicals. To meet these temperature requirements, the chamber typically requires a refrigeration system, which typically includes a compressor, condenser, evaporator, and valves. The condenser typically uses air cooling to exchange heat with the external environment. Specifically, the condenser fan is placed alongside the condenser, and its rotation drives air around the condenser, thereby achieving heat exchange between the condenser and the external environment.

[0003] Currently, air-cooled test chambers typically have the air inlet located at the front of the chamber, opposite the condenser, and the air outlet located at the rear. Due to limited space in the front of the chamber relative to the condenser, the air inlet is small, resulting in low airflow and poor heat exchange. Placing the air outlet at the rear causes heat to accumulate, affecting the comfort of the operator and surrounding personnel. Furthermore, to ensure effective heat dissipation, the rear of the chamber must be clear of obstructions for a considerable distance, resulting in a larger space requirement.

[0004] Therefore, it is urgent to propose an environmental test chamber to solve the above technical problems. Utility Model Content

[0005] The utility model provides an environmental test box, in which the air inlet is arranged at the bottom of the box body and the air outlet is arranged at the top of the box body, which can not only increase the air intake volume, but also avoid heat accumulation at the rear, thereby improving the heat exchange effect and the comfort of the staff, but also reducing the space occupied and improving the space utilization efficiency.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] An environmental test chamber comprising a chamber, wherein the chamber is provided with a test chamber for accommodating test samples and a unit chamber disposed around the test chamber, wherein the unit chamber comprises a first sub-chamber disposed at the bottom of the test chamber and a second sub-chamber disposed on one side of the test chamber, the second sub-chamber being in communication with the first sub-chamber;

[0012] Optionally, a compressor is provided in the second chamber.

[0013] Optionally, the condensing fan is a suction fan, and the suction fan is arranged on a side of the condenser away from the air inlet.

[0014] Optionally, an air-conditioning room is provided between the test chamber and the second chamber, and the air-conditioning room is connected to the test chamber through an air supply port and an air return port. An evaporator, a heater, a humidifier and an air supply fan are provided in the air-conditioning room, and the air supply fan is used to deliver air with a specific temperature and humidity into the test chamber through the air supply port.

[0015] Optionally, a partition is provided between the test room and the air-conditioning room, and the air supply port and the air return port are provided on the partition.

The controller is used to control the alarm to sound an alarm when the temperature and humidity values ​​in the test chamber detected by the temperature and humidity sensor exceed the target temperature and humidity values.

[0018] Beneficial effects of the utility model:

[0019] The utility model provides an environmental test chamber, including a chamber, wherein an air inlet is provided at the bottom of the chamber, and an air outlet is provided at the top. Under the action of a condensing fan, outside air enters the first sub-chamber from the air inlet at the bottom of the chamber to exchange heat with the condenser. The air after heat exchange will enter the second sub-chamber, move upward along the second sub-chamber, and finally be discharged from the air outlet at the top of the chamber. Since the space at the bottom of the chamber is large, the air inlet can be set larger to increase the air intake, thereby achieving the purpose of improving the effect of cooling the condenser.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0028] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation.

[0029] This embodiment provides an environmental test chamber, in which the air inlet is set at the bottom of the chamber and the air outlet is set at the top of the chamber. This can not only increase the air intake volume, but also avoid heat accumulation at the rear, thereby improving the heat exchange effect and the comfort of the staff, reducing the space occupied, and improving the space utilization efficiency.

[0030] Specifically, if Figure 1As shown, the environmental test chamber includes a housing 100, which is provided with a test chamber 110 for accommodating test samples and a unit chamber 120 arranged around the test chamber 110. The unit chamber 120 includes a first sub-chamber 121 located at the bottom of the test chamber 110 and a second sub-chamber 122 located on one side of the test chamber 110, with the second sub-chamber 122 communicating with the first sub-chamber 121. That is, the unit chamber 120 is L-shaped. A condenser 200 and a condensing fan 300 located on one side of the condenser 200 are located in the first sub-chamber 121. An air inlet 130 is provided at the bottom of the housing 100, connecting the outside world to the first sub-chamber 121. The air inlet 130 is located on the side of the condenser 200 away from the second sub-chamber 122. An air outlet 140 is provided at the top of the housing 100, connecting the outside world to the second sub-chamber 122.

[0031] When the environmental test chamber is working, the outside air enters the first chamber 121 from the air inlet 130 at the bottom of the box body 100 under the action of the condensing fan 300 and exchanges heat with the condenser 200. The air after heat exchange will enter the second chamber 122 and move upward along the second chamber 122, and finally be discharged from the air outlet 140 at the top of the box body 100.

[0032] Since the bottom space of the cabinet 100 is relatively large, the air inlet 130 can be set larger to increase the air intake, thereby achieving the purpose of improving the cooling effect of the condenser 200. The air outlet 140 is set at the top of the cabinet 100 so that heat will not accumulate around the cabinet 100, improving the heat exchange effect and the comfort of the staff. In addition, other equipment placed around the cabinet 100 will not be affected, reducing the occupied space and helping to improve the utilization efficiency of the indoor space. In addition, since hot air has a low density and will automatically float upward, arranging the air outlet 140 at the top of the cabinet 100 facilitates centralized exhaust at the top of the room.

[0033] It is understandable that the unit room 120 is used to arrange the refrigeration unit and / or humidification related components. Therefore, arranging the unit room 120 around the test room 110 can improve the structural compactness of the box body 100.

[0034] Optionally, in one possible embodiment, a first dustproof grille is provided at the air inlet 130. By providing the first dustproof grille, while ensuring that the air inlet 130 can reliably take in air, it can prevent external impurities and dust from entering the unit compartment 120 and affecting the normal operation of other components in the unit compartment 120.

[0035] Furthermore, a filter screen having a smaller aperture than that of the first dust grille can be installed on the side of the first dust grille near the first subchamber 121. This arrangement can further filter out dust with smaller diameters, reduce contamination of the condenser 200 by natural air, and improve the operating reliability of the condenser 200.

[0036] Alternatively, in another possible embodiment, the bottom of the housing 100 is provided with a plurality of air inlet holes, which form a mesh-shaped air inlet 130. This arrangement can also ensure reliable air intake while reducing the risk of external dust and impurities entering the unit chamber 120. Furthermore, the structure is simple and easy to manufacture, and no additional dust shielding components are required, thereby reducing component costs.

[0037] Optionally, in one possible embodiment, a second dustproof grille is provided at the air outlet 140. By providing the second dustproof grille, while ensuring that the air outlet 140 can reliably discharge air, it can prevent external impurities and dust from entering the unit compartment 120 and affecting the normal operation of other components in the unit compartment 120.

[0038] Alternatively, in another possible embodiment, the top of the housing 100 is provided with a plurality of air outlet holes, which form a mesh-shaped air outlet 140. This arrangement can also ensure reliable air flow while reducing the risk of external dust and impurities entering the unit chamber 120. Furthermore, the structure is simple and easy to manufacture, and no additional dust shielding components are required, thereby reducing component costs.

[0039] Further, see Figure 1 The unit room 120 is also provided with a compressor 400, which is disposed in the second sub-chamber 122. Since the compressor 400 generates heat when in operation, the compressor 400 is disposed in the second sub-chamber 122. This allows the outside air entering the unit room 120 to exchange heat with the condenser 200 before passing through the compressor 400. The heat of the compressor 400 is taken away from the compressor 400 through the air outlet 140 at the compressor 400. This greatly reduces the risk of the heat generated by the compressor 400 interfering with the operation of the condenser 200 and improves the condensation effect of the condenser 200.

[0040] Optionally, the condensing fan 300 is a suction fan, which is arranged on the side of the condenser 200 away from the air inlet 130. This arrangement allows external cold air to quickly pass through the condenser 200 to exchange heat with the condenser 200, thereby improving the air cooling efficiency of the condenser 200. Of course, the condensing fan 300 can also be a blower fan. In this case, the condensing fan 300 needs to be arranged on the side of the condenser 200 close to the air inlet 130 to improve the heat dissipation efficiency of the condenser 200.

[0041] Further, see Figure 1An air-conditioning room (not shown in the figure) is provided between the test chamber 110 and the second sub-chamber 122, and the air-conditioning room is connected to the test chamber 110 through an air supply port and an air return port. An evaporator, a heater, a humidifier and an air supply fan are provided in the air-conditioning room, wherein the evaporator is used to provide cooling energy, the heater is used to provide heat energy, the humidifier is used to provide humid air, and the air supply fan is used to send air with a specific temperature and humidity into the test chamber 110 through the air supply port. The excess air in the test chamber 110 will return to the air-conditioning room through the return air port, forming a cycle, thereby keeping the temperature and humidity in the test chamber 110 stable. By arranging the air-conditioning room between the test chamber 110 and the second sub-chamber 122, the floor space of the environmental test chamber can be reduced, thereby improving the utilization efficiency of the indoor space.

[0042] Optionally, in this embodiment, a partition is provided between the test room 110 and the air-conditioning room, and the air supply vent and the air return vent are provided on the partition.

[0043] Optionally, continue with Figure 1 A fan cover 150 is provided outside the air supply fan to protect the air supply fan. It is understandable that the fan cover 150 can adopt a hollow structure to block dust while ensuring ventilation.

[0044] Further, see Figure 1 A temperature and humidity sensor (not shown in the figure) is provided in the test chamber 110, and a control chamber 160 is provided on one side of the second sub-chamber 122. A controller is provided in the control chamber 160. The controller is used to control the start and stop of the condenser 200, the evaporator, the heater, the humidifier, and the air supply fan according to the temperature and humidity values ​​in the test chamber 110 detected by the temperature and humidity sensor and the target temperature and humidity values. That is, through the cooperation of the controller and the temperature and humidity sensor, intelligent control of the temperature and humidity in the test chamber 110 can be achieved, which is conducive to improving user satisfaction. In addition, by arranging the control chamber 160 on one side of the second sub-chamber 122, the floor space of the environmental test chamber can be reduced, thereby improving the utilization efficiency of the indoor space.

[0045] Optionally, an alarm 500 is provided on the top of the test chamber 110. The alarm 500 is connected to a controller signal. The controller is configured to control the alarm 500 to sound an alarm when the temperature and humidity values ​​within the test chamber 110 detected by the temperature and humidity sensor exceed target temperature and humidity values. By providing the alarm 500, it is possible to promptly remind staff to perform maintenance when the temperature and humidity within the test chamber 110 are too high, thereby avoiding affecting the accuracy of the test results of the test samples.

[0046] Further, see Figure 1 A door 111 that can be opened and closed is provided on one side of the test chamber 110 for taking in and placing test samples.

[0047] Optionally, a touch screen 600 may be provided on the door 111 , and target temperature and humidity values ​​may be input to the controller through the touch screen 600 , and detection results of the temperature and humidity sensors may be observed.

[0048] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
