Abstract

The invention discloses a water-storage insulating tank of a novel solar water heater, which consists of a tank body 1and an exhaust overflow pipe 2, wherein, a cold-water inlet pipe port 3, a hot-water outlet pipe port 4 and a plurality of solar pipe mounting holes are formed on the wall of the tank body 1; the exhaust overflow pipe 2 which is a spiral water-sealed pipe is horizontally arranged in the cavity of the tank body 1 and close to the top part; the overflow end of the exhaust overflow pipe 2 is hermetically fixed with the wall of the tank body 1 and extends out of the tank body; and the inlet of the exhaust overflow pipe 2 is formed in the spiral center. The water-storage insulating tank has the properties of not only overflow and air permeability, but also heat insulation and frost resistance, and has the advantages of low cost, simple process and easy installation and popularization.

Description

Technical field

[0001] The invention relates to a solar energy device, in particular to a water storage and heat preservation box of a solar water heater. Background technique

[0002] At present, there is an exhaust overflow pipe on the top or above one end of the water storage and incubator of solar water heaters on the market, which is generally a straight pipe or a "T"-shaped elbow, whose function is to exhaust the overflow. These two kinds of pipes also emit a large amount of heat energy at the same time as the exhaust gas overflows. Due to the different geographical latitudes and seasons of the user, nearly 30-80% of the heat is emitted by this pipe. Because of this, due to solar energy The air permeability of the water heater storage and incubator with the atmosphere makes the water temperature in the solar water heater storage and incubator in the northern region in winter not very hot, dissipate a considerable part of the heat through the overflow exhaust pipe, so that t...

Embodiment Construction

[0024] Such as figure 1 As shown, a new type of solar water heater storage and heat preservation box is composed of a box body 1 and an exhaust overflow pipe 2. In the lower part of the box wall of the box body 1, a water inlet and outlet pipe interface 3 and a plurality of solar collector tube insertion holes are provided. The exhaust and overflow pipe 2 is a water-enclosed exhaust and overflow pipe. The shape of the exhaust overflow pipe 2 is spiral. The exhaust overflow pipe 2 is horizontally arranged in the cavity of the box 1 and close to the top. The overflow end of the exhaust overflow pipe 2 is sealed and fixed with the wall of the box 1 and extends. Outside the box, the inlet and outlet of the exhaust and overflow pipe 2 are both at the center of the spiral pipe. The overflow end of the exhaust gas overflow pipe 2 is arranged horizontally.

[0025] Such as figure 2 As shown, a new type of solar water heater storage and heat preservation box is composed of a box body 1 a...
