Problems solved by technology
[0002] Existing flat-panel solar collectors are mainly composed of collector shell, thermal insulation, collector plate core, transparent cover, etc. Through the analysis of relevant research and product test data at home and abroad, it can be known that the heat loss coefficient of the collector increases with the The distance between the cover plate of the heater and the heat absorbing plate increases and decreases rapidly until the plate distance reaches the minimum value when it reaches 10~15mm. Small; in order to control the production cost of heat collectors, the thickness of most heat collectors on the market is between 70~80mm, the insulation thickness is 30mm, and the diameter of copper pipes is 20mm, and then the cover plate, back plate, heat absorbing plate, etc. are removed The thickness is about 5mm in total, and the remaining part is the air space between the cover plate and the heat absorbing plate. The theoretical distance is between 15 and 20mm. During the welding process, welding deformation will occur, and the deformation amount is between 5 and 10mm; this will reduce the actual distance between the heat absorbing plate and the cover plate of the collector to about 10mm after the assembly is completed, which seriously affects the The heat loss coefficient of the collector reduces the light-to-heat conversion efficiency of the flat-panel solar collector

The invention discloses a clamping spring structure of a panel core of a flat-panel solar heat collector. The clamping spring structure is characterized in that spring steel, high-strength stainless steel or tool steel are machined into the clamping spring structure through a spring machining technology, and the clamping spring structure can be pressed on a heat absorbing plate of a panel core structure in a clamped mode. The clamping spring structure is widely suitable for fixing of the panel core structure of the flat-panel solar heat collector, welding deformation of the panel core structure of the heat collector can be corrected, and the photothermal conversion efficiency of the flat-panel solar heat collector is improved.
