[0002] Both vehicle manufacturers and third-party vehicle monitoring units need to conduct sunlight simulation tests on the vehicle to assess the vehicle's ability to receive direct sunlight radiation to produce thermal and light effects, so they all need a vehicle sunlight simulation test chamber. The vehicle sunlight simulation test chamber simulates the temperature and humidity environment required for vehicle testing on the one hand, and simulates sunlight on the other hand, that is, conducts a light test of the vehicle or auto parts under a specified temperature and humidity environment.

[0003] Existing whole vehicle sunlight simulation test chambers generally use full-spectrum lamps for irradiation during tests. However, since the full-spectrum lamps will generate a large amount of heat during the test, the temperature inside the test chamber will rise. If the whole vehicle sunlight simulation test chamber is not cooled down in time, it is easy to cause errors in the final test results. Summary of the invention

[0004] Based on this, it is necessary to provide a whole vehicle sunlight simulation test chamber in view of the problem that the existing whole vehicle sunlight simulation test chamber generally uses full-spectrum lamps for irradiation during the test. However, since the full-spectrum lamps will generate a lot of heat during the test, the temperature inside the test chamber will rise. If the whole vehicle sunlight simulation test chamber is not cooled down in time, it will easily lead to errors in the final test results.

[0033] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] The present application provides a whole vehicle sunlight simulation test chamber.

[0035] like Figures 1 to 8 As shown, in one embodiment of the present application, the whole vehicle sunlight simulation test chamber includes a test chamber body 100, an air cooler 200, a compression condensing unit assembly 300, a cooling assembly 400 and a rotary dehumidifier 500.

[0036] The top surface of the test chamber body 100 is provided with a plurality of full-spectrum lamps 101. The air cooler 200 is fixedly connected to the top surface of the test chamber body 100, and a multi-stage refrigeration evaporator is provided in the air cooler 200. The compression condensing unit assembly 300 is in communication with the air cooler 200. The cooling assembly 400 includes a cooling water tank 401, a circulating water pump 402 and a main pipe 403, the inlet of the circulating water pump 402 is in communication with the outlet of the cooling water tank 401, the outlet of the circulating water pump 402 is in communication with one end of the main pipe 403, the other end of the main pipe 403 is in communication with the inlet of the cooling water tank 401, and the main pipe 403 is provided on the top surface of the test chamber body 100. The rotary dehumidifier 500 is in communication with the air cooler 200.

[0037] like Figure 4 and Figure 6 As shown, the cooling component 400 also includes a temperature regulating member 405, which is arranged between the outlet of the circulating water pump 402 and the inlet of the main pipe 403. The temperature regulating member 405 includes a temperature sensor 406 and an electric heater 407. The temperature of the coolant input into the main pipe 403 is adjusted by the temperature regulating member 405. When the temperature sensor 406 detects that the temperature of the coolant is too low, the electric heater 407 is turned on to heat the coolant, so that the temperature of the coolant reaches the target temperature.

[0038] The coolant is an ethylene glycol solution. Optionally, an ethylene glycol solution with a volume concentration of 45%-50% can be used, and its freezing point is lower than -30°C.

[0039] In this embodiment, air circulation in the test chamber body 100 is achieved by the air cooler 200 cooperating with the compression condensing unit assembly 300. Since a multi-stage refrigeration evaporator is provided in the air cooler 200, the air cooler 200 can realize the functions of ventilation, refrigeration, dehumidification, heating and humidification, and the rotary dehumidifier 500 can directly input dry fresh air into the test chamber body 100, thereby effectively reducing the working pressure of the air cooler 200 and reducing the risk of frost and ice formation of the air cooler 200. The circulating water pump 402 transports the coolant in the cooling water tank 401 to the main pipe 403, and transports the coolant to the full-spectrum lamp 101 through the main pipe 403 to absorb the heat of the full-spectrum lamp 101, thereby reducing the temperature in the test chamber body 100 and reducing the error of the test result.

[0040] like Figure 2As shown, in one embodiment of the present application, the air cooler 200 includes an air cooler body 201, a primary refrigeration evaporator 202, a secondary refrigeration evaporator 203, a tertiary refrigeration evaporator 204, a dehumidification evaporator 205 and an axial flow fan 206, the primary refrigeration evaporator 202, the secondary refrigeration evaporator 203, the tertiary refrigeration evaporator 204 and the dehumidification fan are all fixedly connected to the air cooler body 201, the primary refrigeration evaporator 202, the secondary refrigeration evaporator 203 and the tertiary refrigeration evaporator 204 are arranged in parallel with each other, the dehumidification evaporator 205 is arranged close to the primary refrigeration evaporator 202, and the axial flow fan 206 is fixedly connected to the bottom surface of the air cooler body 201.

[0041] Specifically, the air cooler body 201 further includes a heater 208 and a heating nozzle 209 . The heater 208 is disposed close to the three-stage refrigeration evaporator 204 , and the heating nozzle 209 is disposed close to the axial flow fan 206 .

[0042] Each stage of the refrigeration evaporator 202 of the multi-stage refrigeration evaporator includes a plurality of refrigeration evaporators. For example, if each stage of the refrigeration evaporator 202 includes four refrigeration evaporators, then 12 refrigeration evaporators are arranged in the air cooler body 201 .

[0043] In this embodiment, a multi-stage refrigeration evaporator is provided in the air cooler body 201 to cooperate with the compression condensing unit assembly 300 to achieve a cooling process of the internal space of the test chamber body 100.

[0044] The airflow blown out by the axial flow fan 206 returns to the cold air fan 200 through the bottom air duct and the side wall air duct, and passes through the first-stage refrigeration evaporator 202, the second-stage refrigeration evaporator 203, and the third-stage refrigeration evaporator 204 in sequence, so that the temperature of the airflow after passing through is reduced, and the airflow with reduced temperature is transported to the test chamber body 100 through the axial flow fan 206 again, thereby forming an air circulation inside the test chamber body 100. During this circulation process, the multi-stage refrigeration evaporator can effectively reduce the temperature of the air, thereby reducing the temperature inside the test chamber body 100.

[0045] The dehumidification evaporator 205 can remove moisture contained in the air flow, so the air flow circulating back to the air cooler 200 needs to pass through the dehumidification evaporator 205 before entering the multi-stage refrigeration evaporator to reduce the humidity of the air flow.

[0046] By combining the multi-stage refrigeration evaporator, the dehumidification evaporator 205 and the heater 208, the air cooler 200 has the functions of ventilation, refrigeration, dehumidification, heating and humidification with the assistance of the compression condensing unit assembly 300. Multiple functions are realized through one air cooler 200, effectively saving the internal space of the test chamber body 100.

[0047] like Figure 3 As shown, in one embodiment of the present application, the compression condensing unit assembly 300 includes a first-stage compression condensing unit 301, a second-stage compression condensing unit 302 and a third-stage compression condensing unit 303, the first-stage compression condensing unit 301 is connected to the first-stage refrigeration evaporator 202, the second-stage compression condensing unit 302 is connected to the second-stage refrigeration evaporator 203, and the third-stage compression condensing unit 303 is connected to the third-stage refrigeration evaporator 204.

[0048] Specifically, the primary compression condensing unit 301 is also connected to the dehumidification evaporator 205 .

[0049] In this embodiment, the air treatment in the test chamber body 100 is completed by the compression condensing unit assembly 300 in cooperation with the air cooler 200, and the first-stage compression condensing unit 301 corresponds to the first-stage refrigeration evaporator 202 and the dehumidification evaporator 205, the second-stage compression condensing unit 302 corresponds to the second-stage refrigeration evaporator 203, and the third-stage compression condensing unit 303 corresponds to the third-stage refrigeration evaporator 204, so that each stage of the compression condensing unit 301 corresponds to the corresponding refrigeration evaporator, thereby improving the working efficiency of the compression condensing unit, thereby improving the cooling efficiency of the air in the test chamber body 100.

[0050] like Figure 4 and Figure 5 As shown, in one embodiment of the present application, the cooling assembly 400 further includes a branch pipe 404, one end of the branch pipe 404 is connected to the main pipe 403, and the other end of the branch pipe 404 is connected to the full-spectrum lamp 101, and the coolant in the main pipe 403 is transported to the full-spectrum lamp 101 through the branch pipe 404.

[0051] Specifically, at least two branch pipes 404 are disposed between each full-spectrum lamp 101 and the main pipe 403 , wherein one branch pipe 404 is used to transport the coolant to the full-spectrum lamp 101 , and the other branch pipe 404 is used to transport the used coolant back to the main pipe 403 .

[0052] A hose 408 and a ball valve 409 are also provided between each of the branch pipes 404 and the full-spectrum lamp 101. One end of the ball valve 409 is connected to the branch pipe 404, and the other end of the ball valve 409 is connected to one end of the hose 408. The other end of the hose 408 is connected to the full-spectrum lamp 101. The branch pipe 404 is connected to the full-spectrum lamp 101 through the hose 408, and the ball valve 409 controls the opening and closing of the connection between the hose 408 and the branch pipe 404.

[0053] In the present embodiment, since the test chamber body 100 uses a plurality of full-spectrum lamps 101 to simulate sunlight intensity, but the full-spectrum lamps 101 have high power and generate a large amount of heat, and most of the tests in the test chamber body 100 need to be conducted in a high temperature environment, if the full-spectrum lamps 101 are not cooled, it is easy to cause the full-spectrum lamps 101 to overheat. Therefore, in the present application, a cooling component 400 is provided to reduce the temperature of the full-spectrum lamps 101, thereby ensuring the smooth progress of the test.

[0054] The circulating water pump 402 transports the coolant in the cooling water tank 401 to the main pipe 403, and transports the coolant in the main pipe 403 to the full-spectrum lamp 101 through the branch pipe 404. The coolant can absorb the heat dissipated by the full-spectrum lamp 101 during the process of passing through the full-spectrum lamp 101 to complete the cooling of the full-spectrum lamp 101. After absorbing the heat, the coolant returns to the main pipe 403 and finally returns to the cooling water tank 401.

[0055] like Figure 7 As shown, in one embodiment of the present application, the rotary dehumidifier 500 further includes a front surface cooler 501 , which is disposed at the inlet of the rotary dehumidifier 500 , and the front surface cooler 501 stores cooling water.

[0056] Specifically, an air filter is provided at the inlet of the front surface cooler 501 to filter impurities contained in the fresh air entering the front surface cooler 501 .

[0057] In this embodiment, since the front surface cooler 501 is connected to the cooling water, the fresh air entering the rotary dehumidifier 500 is frozen and pre-dehumidified by the front surface cooler 501 .

[0058] like Figure 8 As shown, in one embodiment of the present application, the whole vehicle sunlight simulation test chamber also includes a flow equalizing plate 207, and the flow equalizing plate 207 is fixedly connected to the bottom surface of the air cooler body 201. The flow equalizing plate 207 is arranged at the lower side of the outlet of the axial flow fan 206, and the outlet air of the axial flow fan 206 is transported to the internal space of the test chamber body 100 through the flow equalizing plate 207.

[0059] Specifically, the current balancing plate 207 includes a bottom plate 207a and a side plate 207b, and the side plate 207b is obliquely disposed on the top surface of the bottom plate 207a.

[0060] The bottom plate 207 a and the side plate 207 b of the flow equalizing plate 207 are both provided with a plurality of evenly distributed openings, so that the axial flow fan 206 can enter the test chamber body 100 through the openings of the flow equalizing plate 207 .

[0061] In this embodiment, the airflow delivered by the axial flow fan 206 is delivered to the test chamber body 100 through the flow equalizing plate 207. Since the side plate 207b of the flow equalizing plate 207 is obliquely arranged on the top surface of the bottom plate 207a, the direction of the airflow will change after passing through the side plate 207b, thereby making the airflow entering the test chamber body 100 more evenly distributed, thereby ensuring uniform temperature and humidity in the test chamber body 100.

[0062] like Figure 7 As shown, in one embodiment of the present application, the rotary dehumidifier 500 also includes a fresh air duct 502, which is fixedly connected to the bottom surface of the air cooler body 201, and the outlet of the rotary dehumidifier 500 is connected to the inlet of the fresh air duct 502.

[0063] Specifically, a rear surface cooler 503 is further provided between the outlet of the rotary dehumidifier 500 and the inlet of the fresh air duct 502 , so as to perform isohypenic cooling treatment on the fresh air entering the fresh air duct 502 .

[0064] In this embodiment, the fresh air pre-treated by the front surface cooler 501 is dehumidified by the rotary dehumidifier 500, so that the fresh air entering the air cooler 200 is sufficiently dry and cooled.

[0065] Combined with the front surface cooler 501, the rotary dehumidifier 500 and the rear surface cooler, the fresh air entering the air cooler 200 is subjected to multiple treatments to ensure that the fresh air entering the test chamber body 100 is sufficiently dry and cooled. Therefore, the fresh air entering the test chamber body 100 does not need to be processed by the air cooler 200, thereby effectively reducing the working pressure of the air cooler 200 and the risk of frost and ice on the air cooler 200, while improving the efficiency of air circulation in the test chamber body 100 and ensuring the accuracy of temperature and humidity control in the test chamber body 100.

[0066] like Figure 2 As shown, in one embodiment of the present application, a plurality of the primary refrigeration evaporators 202 are provided, and the plurality of the primary refrigeration evaporators 202 are symmetrically arranged about the central axis of the air cooler body 201 .

[0067] Specifically, there are multiple secondary refrigeration evaporators 203 and multiple tertiary refrigeration evaporators 204, and the secondary refrigeration evaporators 203 are symmetrically arranged about the central axis of the air cooler body 201, and the tertiary refrigeration evaporators 204 are symmetrically arranged about the central axis of the air cooler body 201.

[0068] In this embodiment, the multi-stage refrigeration evaporator is arranged to be symmetrical, so as to respectively process the airflow from the side wall air duct on the left side of the test chamber body 100 and the side wall air duct on the right side of the test chamber body 100, thereby improving the working efficiency of the air cooler 200.

[0069] like Figure 8 As shown, in one embodiment of the present application, the bottom surface of the test chamber body 100 is fixedly connected with a bottom plate interlayer 102 to form a bottom air duct, and the side wall of the test chamber body 100 is fixedly connected with a side plate interlayer to form a side wall air duct, and one end of the bottom air duct is connected to the side wall air duct, and the other end of the side wall air duct is connected to the air cooler 200.

[0070] In this embodiment, the airflow output by the axial flow fan 206 enters the test chamber body 100 after passing through the flow equalizing plate 207, and finally enters the bottom air duct, and re-enters the air cooler 200 after passing through the bottom air duct and the side wall air duct. After being processed by the air cooler 200, it re-enters the test chamber body 100 through the axial flow fan 206. That is, the air flow path in the test chamber body 100 is: axial flow fan 206-flow equalizing plate 207-bottom air duct-side wall air duct-air cooler 200-axial flow fan 206, thereby realizing the circulation of air in the test chamber body 100.

[0071] like Figure 8 As shown, in one embodiment of the present application, the whole vehicle sunlight simulation test chamber also includes a plurality of return air vents 104, and the return air vents 104 are fixedly connected to the bottom plate interlayer 102, and the plurality of return air vents 104 are symmetrically arranged about the bottom center line of the test chamber body 100, and the return air vents 104 are used to realize the connection between the internal space of the test chamber body 100 and the bottom air duct.

[0072] Specifically, the return air outlet 104 may be configured as a long grid plate.

[0073] In this embodiment, the test product is placed between the multiple return air ports 104 , so that the airflow enters the bottom air duct from the return air ports 104 .

[0074] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
