Abstract

The invention discloses a heat collection device of a solar water heater. The heat collection device of the solar water heater comprises a heat absorption plate obliquely arranged on a frame body and a heat gathering body fixed by the frame body, a heat absorption pipe penetrates through the inner portion of the heat gathering body, and the heat absorption plate covers the exterior of the heat gathering body. The heat absorption plate protrudes upwards and is in a spherical surface shape, and the heat absorption plate comprises a plurality of orthohexagonal convex lenses mutually spliced. Compared with the prior art, the heat collection device of the solar water heater solves the problem that heat generated by an existing solar water heater heat collection device is insufficient under the condition that sunshine light is insufficient.

Description

The solar water heater heat-collecting device

Technical field

The present invention relates to solar water heater manufacturing technology field, especially a kind of collection solar device of solar water heater.

Background technology

Prior solar water heater is to adopt heat energy that solar absorber plate receives sunshine production that the heat exchange in the water tank is realized heating to cold water, uses to satisfy the hot water of people in life, in producing.Solar absorber plate is as a kind of device of collecting energy of water heater, generally be many thermal vacuum endothermic tubes formations that tilt and lay side by side, the vacuum heat absorbing pipe outer tube wall is glass material layer, to receive the direct projection of sunlight, in glass material layer, be provided with the plated film layer to absorb the heat radiation of sunlight, the heat energy that the mode of this light direct projection endothermic tube produces is little, especially under the situation of sunray deficiency, the absorber plate on plane then can not produce enough heat energy, can not satisfy water heater separately to the supply of hot water, the electric heat supply device need be set in addition heat is provided, energy utilization rate is not high.

Summary of the invention

Problem to be solved by this invention provides a kind of solar water heater heat-collecting device, solve existing solar water heater under the situation of sunlight insufficient light, the problem of the shortage of heat that its solar attachment produces.

In order to address the above problem, technical scheme of the present invention is: this solar water heater heat-collecting device includes the absorber plate that tilts to be installed on the support body, have one by the fixing heat build-up body of described support body, described heat build-up body inside has endothermic tube to install and mistake, and the outer cup of described heat build-up body has described absorber plate; Described absorber plate raises up and is sphere, and described absorber plate comprises that the polylith edge of mutual splicing is orthohexagonal convex lens.

In the technique scheme, more specifically scheme can be: described heat build-up body is copper ball or quartz ball.

Further: described convex lens are the convex lens of quartz material.

Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, this solar water heater heat-collecting device principle of adopting convex lens refraction heat absorption produces a large amount of heat energy with solar light focusing to the heat build-up body and heats to hot water, make under the situation of sunray deficiency, convex lens still can produce higher heat energy by optically focused, satisfy the needs that people use hot water;

2, the absorber plate of this solar water heater heat-collecting device be designed to the projection ball-type, can increase the angle of accepting sunshine, make the sun more multi-direction can be by the absorber plate collectiong focusing.

The specific embodiment

Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail:

As Fig. 1, Fig. 2, this solar water heater heat-collecting device shown in Figure 3, it comprises the absorber plate 3 that tilts to be installed on the support body 1, have one by the fixing heat build-up body 5 of this support body 1, the heat build-up body 5 here is ball-type, and this heat build-up body 5 is quartz ball, convex lens 4 to heat build-up body 5, produce a large amount of heat energy with solar light focusing; These heat build-up body 5 inside have endothermic tube 6 to install and mistake, more specifically: the through hole that endothermic tube 6 is opened by this heat build-up body 5 installed heat build-up body 5 from its inside, this through hole is crooked, endothermic tube 6 is the circuitous fully heat of absorption heat build-up body 5 of can trying one's best that arranges in heat build-up body 5, the water that endothermic tube 6 connects in the water tank 2 carries out the water circulation, makes the heat energy on the heat build-up body 5 carry out heat exchange by these several endothermic tubes 6 and water tank 2.The outside of this heat build-up body 5 is covered with absorber plate 3.This absorber plate 3 raises up and is sphere, and projection is the absorber plate of dome-type, and the sun can be received in bigger angle changing, increases the scope of collectiong focusing sunshine; Described absorber plate comprises the orthohexagonal convex lens 4 in the polylith edge of mutual splicing, polylith hexagon convex lens 4 are arranged on the sphere by hexagonal metal framework, regular hexagon is the highest shape of internal area utilization rate in the common figure, can better receive sunshine.Convex lens 4 can select for use the splendid quartz materials of performance such as refractive index and penetrability to make, and increase focusing effect; Adopt heat conduction to do heat build-up body 5 by extremely strong quartz, on the endothermic tube 6 of the metal that heat is delivered to inner constantly generation heat exchange that can be very fast, to speed the firing rate to water in the endothermic tube 6 of metal.

In other embodiments, the heat build-up body can also select for use the splendid copper product of heat conductivility to make.
