Abstract
A solar water heater is formed in the way that a cavity is formed at the bottom part of a vacuum tube, and the vacuum tube is inserted into the cavity to prevent water in a water tank from contacting the vacuum tube. The vacuum tube absorbs the solar thermal energy collected via the cavity so as to heat the water in the water tank from the bottom part thereof. The technology can improve the water heating efficiency of the solar water heater and efficiently solve the common technical problems in the prior vacuum tube solar water heaters.
Description
Affiliated technical field
The utility model is a kind of solar vacuum-tube water heater, can solve the existing ubiquitous technical problem of solar vacuum-tube water heater.
Background technology
At present, well-known solar vacuum-tube water heater hot water principle is by the water in the vacuum tube absorption solar thermal energy heating, vacuum pipe, utilizes the hot and cold water difference of specific gravity to form hot and cold water convection circulation, the water in the heating water heater water tank.The solar vacuum-tube water heater of on this technical foundation, producing, the water in the water tank contacts with vacuum tube, and have a series of total technical problems: hot water efficient is not high; Can only improve the thermal-arrest ability by the way of lengthening, overstriking vacuum tube, cause the waste of glass in the middle of invisible; Solar radiation is at vacuum tube the upper half hot water not; Water vacuum tube bombing on noon; Do not drain water the vacuum tube bursting by freezing and do not reach desirable heat insulation effect winter.
Summary of the invention
In order to overcome the deficiency of existing vacuum light solar water heater, the invention provides a kind of novel solar vacuum-tube water heater.This technology can not only effectively improve the hot water efficient of solar vacuum-tube water heater, and can solve existing solar vacuum-tube water heater and go up water bombing, vacuum tube bursting by freezing in winter, solar radiation noon in vacuum tube the upper half not hot water, the unfavorable problem of heat insulation effect.
The technical scheme that the utility model solves the total technical problem of existing solar vacuum-tube water heater is: do a cavity at the inner water tank bottom position, water in the water tank and vacuum tube are isolated.Vacuum tube is inserted in the cavity, the water in the water tank can not be contacted with vacuum tube.There is not water in the vacuum tube.
The beneficial effects of the utility model are effectively to solve the total technical problem of existing solar vacuum-tube water heater.Under existing working condition, utilize existing manufacturing technique, method to produce, easy to operate.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a drawing in side sectional elevation of the present utility model.
Fig. 2 is the vertical section structural map of the utility model embodiment.
1. inner water tanks among the figure, 2. water, 3. cavity, 4. vacuum tube, 5. heat-insulation layer.
The specific embodiment
In Fig. 1, inner bag (1), cavity (3) are isolated water in the water tank (2) and vacuum tube (4).Vacuum tube (4) is inserted in the cavity (3), and the water (2) in the water tank can not be contacted with vacuum tube (4).
In the embodiment shown in Figure 2, vacuum tube (4) is inserted in the cavity (3), and the water in the water tank (2) can not contact with vacuum tube (4), efficiently solves the problem that goes up water vacuum tube (4) bombing, vacuum tube in winter (4) bursting by freezing noon.The solar thermal energy that vacuum tube (4) absorbs concentrates in the cavity (3), and the water (2) from water tank bottom heating water heater water tank has improved solar energy utilization rate effectively, has solved solar radiation effectively in vacuum tube the upper half problem of hot water not.
Claims (1)
1. solar water heater, vacuum tube does not contact with water in the water tank, it is characterized in that: do a cavity at the vacuum tube bottom position, water in the water tank and vacuum tube are isolated, vacuum tube inserts in the cavity, and the water in the water tank can not contact with vacuum tube, does not have water in the vacuum tube.
