Description

Technical Field

[0001] This utility model relates to the field of temperature control technology, specifically to a temperature control device for testing photovoltaic garden lights. Background Technology

[0002] Photovoltaic garden light testing equipment is used to simulate actual working conditions and comprehensively evaluate the performance of photovoltaic garden lights. In order to ensure more accurate test data, a temperature control device for photovoltaic garden light testing is required to control the internal temperature of the testing equipment, thereby simulating different environmental temperatures to evaluate the performance and stability of photovoltaic garden lights under different climatic conditions, ensuring that the lights can work normally under extreme temperature conditions, and at the same time testing the weather resistance and thermal management capabilities of the lights.

[0003] The existing patents still have the following shortcomings: they have the defect of uneven heating. Since the existing devices are usually installed directly inside the test equipment, the hot and cold air currents generated are unevenly distributed in the test equipment, which can easily cause temperature differences in different parts of the photovoltaic garden light, affecting the performance test of the photovoltaic garden light and making the test results unable to accurately reflect the performance of the light fixture in actual use. Utility Model Content

[0004] This invention provides a temperature control device for testing photovoltaic garden lights, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a temperature control device for testing photovoltaic garden lights, including a first housing, and further comprising:

[0007] Support bases are fixed to both sides of the bottom end of the first housing;

[0008] The compressor is installed at the bottom of the first housing, and the top of the compressor is connected to a condenser that is connected to the first housing.

[0009] The cooling fan is installed inside one side of the cooling fan.

[0010] A connecting pipe is installed on one side of the first housing;

[0011] The second housing is disposed on one side of the connecting pipe, and a turbine fan is installed on one side inside the second housing, and a guide plate connected to the second housing is disposed on the outside of the turbine fan.

[0012] An evaporator is installed inside the second housing, and heating fins are provided at the bottom of the evaporator;

[0013] The diversion pipe is fixed at the bottom of the second housing, and corrugated pipes are fixed on both sides of the bottom of the diversion pipe. An air guide is connected to one side of the corrugated pipe.

[0014] A movable structure is provided on one side of the air duct, wherein the movable structure includes a connecting frame fixed to one side of the air duct, a movable seat installed on one side of the connecting frame, a cover sleeved on the outside of the movable seat, and a power component provided inside the cover.

[0015] A protective structure is located at the bottom of the second housing to block the air inlet of the second housing in the event of a fire.

[0016] Through the above technical solution, the compressor operates to cool the air inside the second housing by evaporator, and the turbine fan draws the air inside the test equipment into the second housing and discharges it through the air duct to cool the environment inside the test equipment. The heating fins heat the air inside the device, thereby increasing the temperature inside the device.

[0017] Furthermore, the power assembly includes a slide rod slidably connected to both sides inside the movable seat and connected to the cover, a screw rod threadedly connected to the movable seat and rotatably connected to the cover, a drive motor mounted on the top of the cover and connected to the screw rod at the end of the output shaft, a pneumatic push rod rotatably connected to one side of the cover, and a rotating seat mounted on the bottom end of one side of the pneumatic push rod.

[0018] The above technical solution uses a drive motor to rotate a screw, which in turn moves the moving seat up and down the air vent. At the same time, the pneumatic push rod extends to further move the position of the air vent, so as to control the temperature of different locations of the photovoltaic garden light.

[0019] Furthermore, slots are provided inside both sides of the cover, and the connecting frame passes through the slots to connect with the movable base.

[0020] With the above technical solution, since the slots are opened on both sides of the cover, the debris generated by the explosion of the photovoltaic garden light is not easily splashed into the inside of the cover.

[0021] Furthermore, the slide rods are provided in two sets, and the two sets of slide rods are symmetrically distributed on the vertical center line of the movable seat.

[0022] The above technical solution guides the movement of the moving seat through two sets of sliding rods on the left and right sides, reducing the shaking of the moving seat.

[0023] Furthermore, the protective structure includes a slide groove fixed to one side of the second housing, a slide rail slidably connected inside the slide groove, a baffle fixed to one side of the slide rail, and a multi-stage push rod rotatably connected to one side of the baffle and rotatably connected to the second housing.

[0024] The above technical solution uses multi-stage push rods to extend and move the baffle to the air inlet of the second housing, blocking the air from entering and preventing flames and smoke from entering the interior of the second housing.

[0025] Furthermore, when the baffle is located at the bottom of one side of the second housing, the multi-stage push rod is in a retracted state, and the slide rail and the slide groove form a sliding structure.

[0026] The above technical solution guides the movement of the baffle by having the slide rail slide inside the slide groove.

[0027] Furthermore, the corrugated pipe is a hollow tubular structure with a wrinkled surface, and the corrugated pipe is a stretchable structure.

[0028] The above technical solution uses a bellows extension and retraction mechanism to guide airflow into the interior of the air duct when the moving structure moves the air duct.

[0029] Furthermore, the back of the first housing is uniformly provided with through holes, and the corrugated pipe is connected to the second housing through a diversion pipe.

[0030] The above technical solution utilizes through holes to facilitate the heat dissipation fan to expel the heat generated by the condenser from the inside of the first housing.

[0031] The above-described solution of this utility model has at least the following beneficial effects:

[0032] 1. This utility model uses a drive motor to rotate a screw, which causes the moving seat to move the air guide up and down. At the same time, the pneumatic push rod extends to further move the position of the air guide, thereby realizing the air direction adjustment function of this device. This ensures that the photovoltaic garden light is heated evenly, reduces the thermal stress on the material caused by temperature differences, and helps to more accurately evaluate the performance of the light fixture under different temperature conditions, thus ensuring the reliability of the test results.

[0033] 2. This utility model uses multi-stage push rods to extend and move the baffle to the air inlet of the second housing, thus blocking it. This achieves the separation and protection function of the device, making it easy to block the air inlet of the second housing in time when the photovoltaic garden light battery has an accident, preventing fragments and flames from damaging its interior and extending the service life of the device.

[0041] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0042] like Figures 1 to 5 As shown, an embodiment of this utility model provides a temperature control device for testing photovoltaic garden lights, including a first housing 1, and further comprising:

[0043] Support base 10 is fixed on both sides of the bottom end of the first housing 1;

[0044] The compressor 11 is installed at the bottom inside the first housing 1, and the top of the compressor 11 is connected to the condenser 12 connected to the first housing 1.

[0045] Cooling fan 2 is installed inside one side of cooling fan 2;

[0046] Connecting pipe 9 is installed on one side of the first housing 1;

[0047] The second housing 5 is located on one side of the connecting pipe 9, and a turbine fan 6 is installed on one side inside the second housing 5, and a guide plate 13 connected to the second housing 5 is provided on the outside of the turbine fan 6.

[0048] Evaporator 14 is installed inside the second housing 5, and heating fins 15 are provided at the bottom of evaporator 14;

[0049] The diversion pipe 16 is fixed at the bottom of the second housing 5, and corrugated pipes 3 are fixed on both sides of the bottom of the diversion pipe 16. An air guide 7 is connected to one side of the corrugated pipe 3.

[0050] The movable structure 4 is disposed on one side of the air vent 7. The movable structure 4 includes a connecting frame 408 fixed on one side of the air vent 7, a movable seat 405 installed on one side of the connecting frame 408, a cover 401 sleeved on the outside of the movable seat 405, and a power component disposed inside the cover 401.

[0051] The protective structure 8 is located at the bottom of the second housing 5 and is used to block the air inlet of the second housing 5 in the event of a fire. The corrugated pipe 3 is a hollow tubular structure with a pleated surface and is a telescopic structure. The back of the first housing 1 is uniformly provided with through holes, and the corrugated pipe 3 is connected to the second housing 5 through the diversion pipe 16.

[0052] In this embodiment of the invention, the first housing 1 is installed on the outside of the photovoltaic garden light testing equipment, and the second housing 5 is installed inside the photovoltaic garden light testing equipment and connected to the control circuit of the photovoltaic garden light testing equipment. When cooling the inside of the testing equipment, the compressor 11 is started to run, so that the compressor 11 draws in the refrigerant and compresses it into a high-temperature and high-pressure gas. Then the condenser 12 releases heat to the external environment, turning the refrigerant into a high-pressure liquid. The high-pressure liquid is injected into the evaporator 14 through the connecting pipe 9 to cool the air inside the second housing 5. The turbine fan 6 draws the air inside the testing equipment into the second housing 5 and discharges it through the air duct 7 to cool the environment inside the testing equipment. When heating, the compressor 11 is turned off and the heating fins 15 are started to heat the air inside the device, thereby increasing the temperature inside the device. The direction of the air duct 7 is adjusted by the moving structure 4 to make the photovoltaic garden light heat evenly. The air inlet of the second housing 5 is protected by the protective structure 8.

[0053] like Figure 4As shown, the power assembly includes a slide rod 402 slidably connected to both sides inside the movable seat 405 and connected to the cover 401, a screw rod 406 threadedly connected to the inside of the movable seat 405 and rotatably connected to the cover 401, a drive motor 403 installed at the top of the cover 401 and connected to the screw rod 406 at the end of the output shaft, a pneumatic push rod 404 rotatably connected to one side of the cover 401, and a rotating seat 407 installed at the bottom of one side of the pneumatic push rod 404. The inside of both sides of the cover 401 is provided with slots, and the connecting frame 408 passes through the slots and is connected to the movable seat 405. Two sets of slide rods 402 are provided, and the two sets of slide rods 402 are symmetrically distributed on the vertical center line of the movable seat 405.

[0054] In this embodiment of the utility model, the drive motor 403 is started to drive the screw 406 to rotate, so that the moving seat 405 moves linearly through the thread on the surface of the screw 406. At the same time, the slide rod 402 guides the movement of the moving seat 405 and reduces the shaking of the moving seat 405. The moving seat 405 drives the air guide 7 to move up and down through the connecting frame 408, so that the air guide 7 can adjust the temperature of different positions of the photovoltaic garden light. At the same time, the pneumatic push rod 404 extends and pushes the cover 401 to rotate around the rotating seat 407, further moving the position of the air guide 7, so as to control the temperature of different positions of the photovoltaic garden light.

[0055] like Figure 5 As shown, the protective structure 8 includes a slide groove 803 fixed to one side of the second housing 5, a slide rail 801 slidably connected inside the slide groove 803, a baffle 804 fixed to one side of the slide rail 801, and a multi-stage push rod 802 rotatably connected to one side of the baffle 804 and rotatably connected to the second housing 5. When the baffle 804 is located at the bottom of one side of the second housing 5, the multi-stage push rod 802 is in a retracted state, and a sliding structure is formed between the slide rail 801 and the slide groove 803.

[0056] In this embodiment of the invention, when a deflagration accident occurs inside the photovoltaic garden light testing equipment, the multi-stage push rod 802 is extended by activating it, causing the multi-stage push rod 802 to push the baffle 804 to move. At the same time, the slide rail 801 slides inside the slide groove 803, guiding the movement of the baffle 804. This causes the multi-stage push rod 802 to push the baffle 804 to the air inlet of the second housing 5 and block it, preventing the air from entering and preventing flames and smoke from entering the interior of the second housing 5.

[0057] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
