Problems solved by technology

[0016] In paper 4, the water convection conditions in the heat collecting tube and the water storage tank are described, but the conclusion is that to determine the inclination angle of the heat collecting tube, the latitude factor and the heat convection factor need to be considered comprehensively, and it is not concluded that the water from the heat collecting tube enters the water storage tank The hot water is diverted to improve the thermal state, and then change the convection state in the heat collecting tube and the convection state of the water in the water storage tank.

Embodiment Construction

[0034] exist figure 1 In , the specific embodiment of the present invention is expressed in the form of perspective view, illustrating the structure of the deflector manufactured by applying the present invention.

[0035] The deflector is composed of a hot water channel 1 and a connecting ring 2. The hot water channel 1 is a curved curved surface extending axially along the connecting ring 2. The two sides of the curved surface hang down, and the curved surface protrudes The direction is upward, and the tail of the arc is upturned.

[0036] Considering that the heat collecting tube is made of glass and has a low ability to withstand stress, it is necessary to open a telescopic gap 3 on the connecting ring 2 of the deflector so as to cooperate with the nozzles of the heat collecting tubes that are different from each other, and to provide protection for thermal expansion and cold contraction. out of expansion space.

[0037] In consideration of minimizing the heat exchange b...

Abstract

The invention relates to a diversion plate of a solar water heater, in particular to a hot water diversion device capable of leading hot water in a heat collection pipe into a water storage tank for effective heat exchange. By the diversion plate, the problem of convection between hot water and cold water in the solar water heater is expected to be solved from sources, the hot water in an inner pipe of the heat collection pipe smoothly ascends along a sunny side, enters the water storage tank, rapidly floats along the diversion plate and exchanges heat with the cold water in a larger space, and the cold water in the water storage tank smoothly enters the heat collection pipe, descends along a shady side and fills the remaining space. The diversion plate consists of a connecting ring and a hot water channel; the hot water channel is a curved cambered surface axially extending along the connecting ring; the two side edges of the cambered surface hang down; the protruding direction of the cambered surface faces upwards; and the tail part of the cambered surface is bent upward and extends to a hot water area of the water storage tank. The diversion plate is installed on the ordinary solar water heater, and can improve the convection of water in the heat collection pipe and the water storage tank, increase the circulated speed of the water and improve the heat collection efficiency.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a hot water guide device capable of effectively exchanging heat after hot water from a heat collecting pipe enters a water storage tank. Background technique [0002] In 1995, Beijing Tsinghua University Solar Electronics Factory invented the all-glass vacuum solar heat collector, patent number 95215311.4. The lower end of the heat collecting tube using this patented technology is closed, the upper end is open, and the upper end is inserted into the water storage tank, which has become a typical structure of solar water heaters. The water absorbs heat energy in the inner tube of the heat collecting tube, and the water naturally circulates between the inner tube of the heat collector and the water storage tank, and the water in the water storage tank gradually becomes hotter. Since then, research and exploration schemes for improving the performance of solar water heaters have emerged cont...
