ABSTRACTSolar ABSTRACT Solar energy has great potential in building，using solar energy to meet the demand of low grade energy consumption of the hot water and heating．The subject of using solar energy as heat source，and the separation type heat pipe as heat transfer components，the combination of wall hanging type solar water heater and the inner wall of a separation type solar heat pipe heating device，using the wail radiation of room heating．at the same time、忻m hot water supply function．This device uses solar energy,consumes no extra power,and realizes the integration of the components and buildings． Separate type heat pipe solar heating device to convert solar energy into hot water,using heat tube latent heat of vaporization．heat transfer characteristics of the heat is transferred to the inner wall and by the wall of heat storage and release of heating is realized．The main component is collector,heat storage tank，separated heat pipe and inner wall．Compared、析m other heating modes，separate type heat pipe solar heating device with the use of clean and renewable energy as heat source，high efficiency heat transfer,comfortable and hidden，no heating power and other advantages and disadvantages in the daytime heat collection and heat at night． This paper selects the Nanjing area of a residential building south standard layer of two rooms，on the device core heat transfer element of separate type heat pipe design．First according to the heat source condition，suitable working medium， calculation and comparison of water and ammonia under different working temperature of heat pipe performance impact is the key thermophysical properties， that the most suitable medium for water，heat pipe operating temperature is 40 DEG C， working pressure for 7375 Pa；and then select the shell and tube material and size， best for 304 stainless steel，diameter 1 6 mill，the wall thickness of 1 ITlln and checking the pressure． 万方数据 Finally,we Finally,we illustrate the filling rate of heat pipe and two
