Heat exchange device for solar water tank

Abstract

The invention discloses a heat exchange device for a solar water tank. The device comprises a mounting seat (1) and a copper coil tube (2), wherein the water inlet and the water outlet of the copper coil tube (2) are both formed on the mounting seat (1); the inner cavity of the copper coil tube (2) is provided with a supporting rod (3) which is fastened to the mounting seat (1); a supporting ring (4) arranged in the inner cavity of the copper coil tube (2) is sleeved on the supporting rod (3) through a mounting hole which forms an angle of 120 degrees with the supporting ring (4); and each circle of the copper coil tube is fastened to the supporting rod (3) through isometric pressure parts (5). Due to the adoption of the structure, water in the water tank is used as a heat transfer medium, and water in the copper coil tube is used as domestic water, so that water pollution is avoided; and in addition, the isometric pressure parts make the interval of the coil tube equal, prevent the copper coil tube from being deformed, and make water temperature uniform and comfortable.

Description

technical field [0001] The invention relates to a solar water tank, in particular to a heat exchange device for the solar water tank. Background technique [0002] With the popularity of solar water heaters, users have higher and higher requirements for the functions of water heaters. The structure of the solar water tank of the prior art generally includes a shell, water inlet and outlet pipes, a heat exchanger and an inner container. In addition to electric heating, this kind of water tank can also carry out medium circulation through the heat exchanger in the water tank, thereby improving the heat exchange effect of the water tank. Since this solar water tank is a pressure-bearing structure, there will be potential safety hazards during use. In addition, the domestic water of this kind of solar water tank is stored in the water tank, which will cause water pollution after a long time, and the use of the solar water tank is limited because the hot water cannot be guarant...
