[abstract]:With the development of solar heating technology,The research of collector technology in the solar water heater system has attracted growing attention in the word.The coupling application of separate type heat pipe flat plate solar water heater and indoor heating system,Can effectively improve the stability of heat collecting efficiency and heating system of the solar collector,also to promote the optimal allocation of energy.In this paper, combined with the development trend of solar thermal utilization and the domestic heat pipe flat plate solar research and development direction of heat collector at present, To apply the separate type heat pipe principle to the flat plate collector,The purpose is to research and development of new solar rational application of heat collector.This article attempts to take the area of hot summer and cold winter climate conditions,Simulation of separated heat pipe collector operating characteristics and the structure parameters and working principle.Heat pipe is a high efficient heat transfer component,It has been widely used in the world.

In this paper, the research and development of solar collector, the technical source of ordinary hot pipe, the working performance and heat conversion principle of the separation heat pipe, and the selection principle of the liquid refrigerant are introduced. This paper discusses the feasibility of separate type heat pipe flat plate solar collector and indoor heating device coupling application; physical model and physical model of indoor heating, heating heat collecting components were established; expounds the connection mode of separate type heat pipe flat plate solar collector and the heat storage water tank; the flat plate solar energy the collector is arranged in the heat pipe evaporator evaporation end; a heat pipe condenser is arranged in the heat storage tank, heat flow through the steam output pipe and condensate return pipe connecting the evaporator and the condenser; in the heat storage water tank is provided with a temperature sensor in the condensate reflux pipe is arranged flow control pump (An Quanbeng), the transfer control flow pump working state signal through the temperature sensor. Heat exchanger is arranged in the heat storage water tank, one end of the heat exchanger through the hot water storage tank is arranged at one end of the plate and the air inlet fan connection; the other end of the heat exchanger through the heat storage water tank on the other side of the end plate and the exhaust fan is connected with; the air inlet fan and vent fan are mounted in the interior, such a system of the heat storage tank in maintaining daily washing and bathing water but also provide indoor heating. In addition, encounter extreme weather and rainy days, the system can be through the intelligent control device and the auxiliary heating device of heat storage water tank heating; when necessary can also be the nocturnal peak valley price of electricity for heat storage, improve the economy of the system.
