The efficiency of the Solar collector depends upon the fluids used in the Solar collector and thermal performance also can be enhanced by using heat pipes in the Solar collector. Compared to flat plate solar collectors, the major disadvantage of heat loss can be rectified in heat pipe solar collectors.
Live ChatHP (Heat Pipe) collector systems Based on their hydraulic properties, HP collectors are able to be integrated with an angle of 20-90° on any building ( pitched roof, facade or even free standing). The s-power HP collectors are used for solar drinking water, pool heating, furnace support and process heat. Under the influence of the heat,
Live ChatThe SPP evacuated tube system uses what is called a heat pipe. A heat pipe allows for rapid heat transfer. The heat pipe itself is a copper tube that maintains a vacuum and contains a small amount of liquid. The low pressure (vacuum) in the copper pipes means that the liquid boils at a low temperature (about 30 ⁰C / 86 ⁰F), turning to steam ...
