Abstract

The utility model relates to a coiled pipe solar energy water heater without welding. The utility model is characterized in that a heat adsorption pipe is positioned and coiled on a heat absorption plate; the shape of the coiling of the heat absorption pipe is a multiple rows of U-shaped snake shape; the heat absorption pipe is connected with a water storing tank by pipe hoops; the whole of the utility model is in a cuboid structure; the heat absorption plate is arranged under the water storing tank; the heat absorption pipe is arranged on the heat absorption plate; transparent glass is arranged on the heat absorption pipe; a heat insulation layer is arranged under the heat absorption pipe. The utility model reduces welding processes and saves cost. The utility model stops welding faults. Because the utility model adopts one pipe to roil, the heat absorption circle of the utility model is accelerated, and heat absorption efficiency is increased.

Description

There is not welding coiled pipe solar water heater

The utility model belongs to and utilizes solar source to carry out a kind of device that heat exchange adds hot water, a kind of water heater of the outdoor direct irradiation of sunlight of particularly suitable.

Before the utility model, the solar water heater of selling on the market has copper pipe welding and two kinds of forms of glass-vacuum tube, the price of glass-vacuum tube is expensive, the copper pipe valency is lower, but the copper pipe welding is because the quality problems of welding, weld easily leaks after often being prone to trachoma or corrosion, so solve the solar water heater Welding Problems, is the improved major issue of solar water heater.

The utility model is achieved in that not having welding coiled pipe solar water heater is by coiled pipe, absorber plate, critical pieces such as storage tank shell are formed, this water heater is rectangular structure, the storage tank shell is set above the cuboid shell, the storage tank housings is provided with garden shape storage tank, the inside of cuboid shell is provided with the black matrix absorber plate, the U-shaped coiled pipe that the top setting of absorber plate is formed by a copper pipe or aluminum pipe bending, one end of coiled pipe upper hose connects the pipe collar above the storage tank, the other end connects the threeway above the water inlet pipe and water outlet pipe, the other end of threeway connects the return pipe on the storage tank, the lower floor of absorber plate is provided with heat-insulation layer, be provided with below the shell can translation-angle travel(l)ing rest, water inlet pipe and water outlet pipe is at first sent into storage tank to cold water, by the heat absorption of the coiled pipe on the absorber plate hot water in the coiled pipe and the cold water in the storage tank are carried out heat exchange, return spray head for shower by water inlet pipe and water outlet pipe again after the heating.

The utility model has reached design purpose, compare with the water heater of former copper pipe welding, the utility model adopts does not have pipe coiling of welding, has reduced the many places pad of former comb, has saved the operation process, and coiled pipe is than the easier quickening heat exchange of former comb, improved heating efficient,, reduced fault owing to there is not solder joint, reduce corrosion, improved the service life of water heater.

Further describe in conjunction with the accompanying drawings and embodiments:

Accompanying drawing is not have the solar water heater integrated structure chart of welding coiled pipe.

Among the figure:

1, absorber plate.

2, coiled pipe.

3, shell.

4, outer surface glassy layer.

5, upper hose.

6, storage tank shell.

7, overflow pipe.

8, storage tank.

9, return pipe.

10, travel(l)ing rest.

11, heat-insulation layer.

12, water inlet pipe and water outlet pipe.

13, threeway.

14, pipe collar.

An embodiment of the present utility model is: according to above-mentioned design, 1.6 meters of a kind of nothing welding coiled pipe solar water heater height overalls have been made, wide 1 meter, thick 10 centimetres, on the absorber plate of 1.2 square metres heat exchange areas, 5 circle U-shaped coiled pipes have been coiled, coiled pipe adopts copper pipe, the diameter of storage tank is 36 centimetres, and length is 95 centimetres, compares with the solar water heater of the welded pipe of the same endotherm area of same length, has the advantage that reduces welding procedure, and reduced the welding steam vent and lost the deficiency of leaking, heat transfer and endothermic effect are better than the solar water heater of welded pipe, are the regeneration products of welding comb solar water heater.
