PURPOSE:To easily construct a low-cost underground heat storing and collecting device having a simple structure and excellent heat exchange efficiency by a method in which the device is made up of a heat exchanger having a high heat exchangeability, and the inside of the heat exchanger is divided into plural heat exchange chambers isolated by partition walls at given intervals in such a way as to connect the heat exchange chambers in zig-zagged form. CONSTITUTION:In a heat exchanger body 1 made of a hollow box of a material having a high heat exchangeability, a high water resistance, and a high water impermeability, made of plastic film, etc., the facing end portions are provided with a heat medium supply port 2 and a heat medium outlet 3, leading to the inside of the heat exchanger body 1. Also, in the heat exchanger body 1, plural heat exchange chambers 5a, 5b, and 5c, having the similar volumes, are formed by plural partition walls 4 set in parallel at a given interval in the longitudinal direction. Since an upper communication section 6a and a lower communication section 6b mutually biased vertically are formed in the upper and lower end portions of each partition wall 4, the heat exchange chambers 5a, 5b, and 5c are mutually connected in such a way that the heat medium can move in zig-zagged manner in the heat exchanger body 1. |
