Description

A kind of vacuum pipe solar water heater

Technical field:

The utility model relates to field of solar energy utilization, is specifically related to vacuum pipe solar water heater.

Background technology:

At present, vacuum pipe solar water heater, because of its thermal efficiency height, volume is subjected to the consumer for a short time and welcomes, and becomes the main product of solar water heater, and occupation rate of market reaches more than 95%.Along with the raising of people's living standard, the consumption of hot water is increasing, and is therefore, also more and more higher to manufacturing hot water ability, the stored hot water Capability Requirement of solar water heater.And vacuum pipe solar water heater of the prior art, the storage tank traverse is in a top of the trellis, vacuum tube and ground approximately with the miter angle oblique cutting in the storage tank side lower part, in order to improve its heat supply outlet capacity, can only take to extend, overstriking vacuum tube or the number that increases vacuum tube solve.Therefore, present vacuum pipe solar water heater, or be many numbers vacuum tube join with long storage tank, the defective of existence is: the storage tank surface area is bigger, and heat loss is more, the day of hot water, night, the temperature difference was big, had wasted energy.Be with the vacuum tube of overstriking, lengthening join with thick storage tank, the defective of existence is: be positioned at the storage tank of tall and big top of the trellis, its center of gravity is more and more higher from mounting plane, wind loading rating then can be more and more a little less than, exist potential safety hazard when blowing hard.The defective that prior art also exists is: because the vacuum tube oblique cutting is in the storage tank side lower part, the hot water of storage in its tube chamber, because of upwards can't flowing out for the user, uses its mouth of pipe, form the hot water dead angle, not only reduced the hot water use amount, in the course of time, easy breed bacteria influences water quality in the pipe, the easy scaling of tube wall influences the heat conduction simultaneously, reduces collecting efficiency.

Summary of the invention:

The technical problems to be solved in the utility model provides a kind of vacuum pipe solar water heater, under heat supply outlet capacity equal conditions, storage tank is close to mounting plane, no dangerous anxiety, the surface area of storage tank is little, and heat loss is few, and the hot water in the what is more important vacuum tube chamber can use for the user, the vacuum tube tube wall is less scaling, and collecting efficiency is stable.

The utility model is achieved through the following technical solutions:

A kind of vacuum pipe solar water heater comprises storage tank, support member, is connected in vacuum tube between the two, and described vacuum tube is arranged at the both sides of storage tank respectively.

A kind of vacuum pipe solar water heater comprises storage tank, support member, is connected in vacuum tube between the two, and described vacuum tube is arranged at the both sides of storage tank respectively, and the horizontal sextant angle of vacuum tube is more than or equal to 0 degree, less than 90 degree.

A kind of vacuum pipe solar water heater, comprise storage tank, support member, be connected in vacuum tube between the two, described vacuum tube is arranged at the storage tank both sides respectively, the horizontal sextant angle of vacuum tube is more than or equal to 0 degree, less than 90 degree, line horizontal sextant angle between every side vacuum tube is more than or equal to 0 degree, less than 90 degree.Line between the described vacuum tube is line or the tangent line line between the vacuum tube tube hub.

Described vacuum tube is arranged at the storage tank both sides respectively, for five equilibrium is symmetricly set in the both sides of storage tank, or with the fan-shaped angle of storage tank bisector greater than 0 degree, be symmetricly set in the storage tank both sides smaller or equal to 90 degree.Too big with the fan-shaped angle of bisector, then can reduce gradually as surpassing 90 its collecting efficiencies of degree.

The utility model compared with prior art has following obvious advantage:

One, the utility model is symmetricly set in the storage tank both sides with vacuum tube, and under same heat supply outlet capacity condition, it is about 1/2nd that the length of storage tank can shorten, thereby dwindled the storage tank surface area greatly, reduced thermal losses.

Two, the utility model directly is installed on mounting plane with an end of storage tank by base, and not only wind loading rating is strong, safe and reliable, and cost low (without support).

Three, the horizontal storage tank both sides that insert in of vacuum tube of the present utility model, hot water in the chamber can all flow out for the user and use, no hot water dead angle, increased the hot water supply, improve the utilization ratio of water heater, owing to manage the outflow that flows to of interior hot water, constantly taken away incrustation scale simultaneously, solve the vacuum tube encrustation, influenced the problem of heat conduction, collecting efficiency reduction.

To sum up, the utlity model has advantages such as the volume that takes up space is little, heat loss is few, collecting efficiency is stable, the heat supply water yield is big, safe and reliable.
