Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module testing technology, specifically to a side illumination system device for a photovoltaic module ultraviolet humidification and freezing comprehensive test chamber. Background Technology

[0002] Traditional photovoltaic module environmental test chambers have the following drawbacks:

[0003] 1. UV light sources are often placed at the top or front of the chamber, conflicting with the air circulation path and resulting in poor temperature and humidity uniformity. 2. Single-layer light-transmitting structures are prone to heat accumulation, affecting spectral stability. 3. The integrated design of the refrigeration unit and the test chamber leads to vibration interference with test accuracy. For example, common test chambers use a top-lit mode, which cannot meet the side irradiation requirements of double-sided components; the integrated layout of the refrigeration system and test chamber in common test chambers causes excessive temperature fluctuations within the chamber.

[0004] Therefore, there is an urgent need to develop a comprehensive testing device that supports uniform side illumination, precise temperature and humidity control, and structural stability. Utility Model Content

[0014] The beneficial effects of this utility model are as follows:

[0015] In this device, a detachable ultraviolet lamp box is laterally connected to the test chamber, enabling vertical side irradiation of the photovoltaic modules. The lamp box uses double-layer high-transmittance ultraviolet optical glass to form a heat-insulating and light-transmitting layer.
