Description

Technical Field

[0001] This utility model relates to the technical field of aging tests, and in particular to a high and low temperature ultraviolet aging chamber. Background Technology

[0002] Existing high and low temperature UV aging chambers include a working chamber and a control chamber. The working chamber contains a test chamber, and the top of the working chamber is equipped with several transparent glass panels and light boxes on the transparent glass panels. The control chamber controls the temperature and humidity changes inside the test chamber. When the test chamber is undergoing low-temperature cycling, or when the equipment is rapidly cooled down from a high-temperature state, the light boxes themselves generate heat during operation, and their surface temperature is relatively high. Meanwhile, the temperature of the transparent glass panels below and the top of the working chamber will decrease significantly during low-temperature cycling. Water droplets or mist will condense on the side of the transparent glass panels facing the light boxes, resulting in a decrease in the intensity of UV light actually irradiating the samples inside the test chamber and uneven distribution, which seriously affects the accuracy of the test conditions.

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Example:

[0029] A high and low temperature ultraviolet aging chamber includes a working chamber 100 and a control chamber 200.

[0030] Figure 1 This is an isometric view of a high and low temperature ultraviolet aging chamber according to this utility model. Figure 2 This is a top view of the high and low temperature ultraviolet aging chamber of this utility model. Figure 3 This is a side view of the high and low temperature ultraviolet aging chamber of this utility model. Figure 4 This is a schematic cross-sectional view of a high and low temperature ultraviolet aging chamber according to this utility model. Figures 1-4 As shown, a test chamber 101 is provided inside the work box 100. Several frames 102 are located at the top of the work box 100, with openings 103 at the top of each frame 102. Several light-transmitting holes 104 are located at the top of the work box 100 and are situated within the frames 102. The test chamber 101 communicates with the light-transmitting holes 104. A light-transmitting glass 105 is detachably connected to the bottom of each light-transmitting hole 104. A photovoltaic module is placed inside the test chamber 101. A light box 300 is located at the top of the light-transmitting holes 104, and ultraviolet light from the light box 300 shines into the test chamber 101 through the light-transmitting glass 105. A sealing cover 106 is hinged to one side of the top of each frame 102 along its length, closing the openings 103 and sealing the frame 102. For example, the work box 100 has an entrance 107 on the side away from the control box 200, and a door 108 is symmetrically hinged on the side of the work box 100 away from the control box 200, and a door lock assembly 109 is provided on the door 108.

[0031] Figure 5This is a rear view structural diagram of a high and low temperature ultraviolet aging chamber according to this utility model. Figures 4-5 As shown, a control box 200 is located on one side of the working chamber 100. The control box 200 contains a control mechanism, part of which extends into the test chamber 101. The control mechanism is configured to control the temperature and humidity changes within the test chamber 101. For example, the control mechanism includes a temperature control module 210 and a humidification module 220. The working chamber 100 has a vent 110. The humidification module 220 includes a evaporation chamber with a water inlet, a heating element inside, and an exhaust pipe connected to the test chamber 101. A humidification pipe is connected to the end of the exhaust pipe away from the evaporation chamber. The humidification pipe is located inside the working chamber 100, with both ends of the humidification pipe closed axially, and has multiple humidification holes.

[0032] like Figure 2 As shown, furthermore, there are two frames 102, which are arranged at the top of the working box 100 with a front-to-back gap. Several light-transmitting holes 104 are distributed left-to-right within the frames 102. By grouping the light-transmitting holes 104 into two independent frames 102, the light source of the lamp box 300 is divided into zones for coverage, ensuring the uniformity of ultraviolet irradiation in the area of ​​the test chamber 101 corresponding to the left-to-right spaced light-transmitting holes 104, and avoiding light attenuation or edge effects caused by an excessively long single frame 102.

[0033] like Figure 2 As shown, a cylinder 400 is further provided at the top of the work box 100. The cylinder 400 is located on one side of the frame 102 along the width direction. The piston rod of the cylinder 400 is connected to the side of the encapsulation cover plate 106 away from the hinge. When the telescopic rod of the cylinder 400 extends or retracts, the encapsulation cover plate 106 opens or closes the opening 103. By controlling the extension and retraction of the telescopic rod of the cylinder 400, the side of the encapsulation cover plate 106 is directly driven to complete the sealing or opening of the opening 103, improving the automation level and operating efficiency of the equipment, ensuring the reliability of the seal, and avoiding problems such as uneven force or poor sealing that may occur during manual closing.

[0034] like Figure 2 As shown, furthermore, two symmetrical cylinders 400 are provided on both the left and right sides of the encapsulation cover 106. The cylinders 400 on both sides apply force simultaneously to counteract the torque of the encapsulation cover 106 during the opening and closing process. The double driving force ensures the stability of the encapsulation cover 106 when closed, and significantly improves the airtightness of the frame 102.

[0035] like Figure 2As shown, furthermore, the bottom end of the cylinder body of cylinder 400 is hinged to the top end of the working box 100, and the end of the piston rod of cylinder 400 is hinged to the side of the encapsulation cover plate 106 away from the hinge point. The hinge between the bottom end of the cylinder body and the top of the working box 100 allows cylinder 400 to adaptively swing with the changing opening and closing angle of the cover plate during piston rod extension and retraction, reducing wear on cylinder 400, extending its service life, and avoiding frame deformation or sealing surface misalignment that may be caused by rigid connections.

[0036] like Figure 2 and Figure 4 As shown, furthermore, the top of the working chamber 100 is equipped with several motors 500, the output ends of which extend into the test chamber 101. Impellers are connected to the output ends of the motors 500. The top of the working chamber 100 is equipped with several vortex tubes 600, the air outlets 601 of which are connected to the test chamber 101. Impellers extend into the vortex tubes 600, and air inlets 602 are located at the lower end of the vortex tubes 600, with humidification holes facing the air inlets 602. The motors 500 drive the impellers to rotate at high speed within the vortex tubes 600, forcefully drawing gas in from the air inlets 602 at the lower end of the vortex tubes 600. The humidification holes spray saturated steam generated by the evaporation chamber into the humidification chamber, allowing the gas to undergo moisture mixing within the vortex tubes 600. After being accelerated and pressurized by the vortex tubes 600, the mixed airflow is injected into the test chamber 101 from the air outlets 601 in a uniform and stable jet form, ensuring that the photovoltaic modules can withstand controllable heat and humidity changes during drastic temperature cycles.

[0037] In operation, this embodiment is as follows:

[0038] First, the photovoltaic module is placed in the test chamber 101, the chamber door 108 is closed and the working chamber 100 is sealed by the door lock assembly 109, and at the same time the cylinder 400 is started to push the piston rod, which drives the encapsulation cover plate 106 to rotate around the hinge point until the opening 103 at the top of the frame 102 is tightly closed, forming a sealed space; then the inside of the frame 102 is evacuated. The temperature control module 210 inside the control box 200 adjusts the temperature of the test chamber 101 through the ventilation port 110. At the same time, the humidification module 220 is activated, and the heating element in the evaporation chamber vaporizes the water. The steam is transported to the humidification pipe through the exhaust pipe and sprayed out through the humidification hole. At this time, the motor 500 drives the impeller to rotate at high speed in the vortex tube 600, drawing gas in from the air inlet 602 at the lower end of the vortex tube 600. After being fully mixed with the steam sprayed out of the humidification hole, the gas is accelerated by the vortex tube 600 to form a uniform airflow, which is then forcefully injected into the test chamber 101 from the air outlet 601, achieving rapid and balanced temperature and humidity. The light box 300 continuously emits ultraviolet rays, which penetrate the vacuum-isolated light-transmitting glass 105 to irradiate the photovoltaic module in the test chamber 101, simulating the aging process under harsh conditions. The control mechanism dynamically adjusts the temperature and humidity parameters and maintains airflow circulation and ultraviolet irradiation until the set test duration is completed.

[0039] In this embodiment, a sealing cover 106 that can close the opening 103 is hinged to the top of the frame 102, so that the frame 102 can be effectively sealed. The internal space of the sealed frame 102 is evacuated, and there is no air in the area of ​​the light-transmitting hole 104 below the light box 300. When the equipment is subjected to low temperature or high and low temperature rapid alternation test, the cold and hot interface will not produce water vapor or condensation. This avoids the problem of reduced intensity and uneven distribution of ultraviolet light irradiated on the photovoltaic module caused by the scattering and absorption of ultraviolet light by water droplets or water mist, and ensures the accuracy of the test conditions.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
