Since the solar heating system is closely integrated with the building, the combination of heat collection products and buildings, failure rate, service life and other performance requirements are high. The flat plate heat collector has simple structure, pressure resistance, external force impact resistance, and is suitable for pressure-bearing operation, and is very suitable for combining with the building in terms of overall appearance, structural strength, installation and operation. Dezhou Jinheng New Energy Co., Ltd. is located in Dezhou, Suncity, China. It specializes in R&D, production and application of high-performance solar collectors. The company has developed products suitable for different temperatures and environments, such as: flat plate heat collectors, heating collectors, air collectors, vacuum tube collectors, large heat pipe collectors, CPC collectors, U-tube collectors. System applications: solar thermal utilization, solar urban heating, solar rural heating, solar agricultural heating, drying, solar industrial heat, etc., are widely praised by the market, supplying heat collectors to hundreds of enterprises nationwide, and have been designated as long-term cooperative flat plate heat collector suppliers by many enterprises.
