Abstract
The invention discloses a heat-preservation water tank of a solar water heater. The heat-preservation water tank comprises a tank body, wherein the tank body is provided with a water inlet, a water outlet and a heat collection pipe inserting port; the tank wall of the tank body is partitioned into two layers; the inner layer of the tank wall is provided with low-melting-point wax; and the outer layer of the tank wall is filled with a foamed layer. Since the low-melting-point wax absorbs heat when the temperature of water in the water tank is high and releases the heat when the temperature of the water is low, the temperature of the water in the water tank can be kept for an extremely long time, and the heat-preservation water tank of the solar water heater has a good heat-preservation effect, particularly the heat-preservation time of the water tank can be prolonged in winter.
Description
Technical field
The present invention relates to a kind of attemperater of solar water heater, specifically a kind of attemperater that can be incubated and can release heat.
Background technology
The attemperater of existing solar water heater all is to add foaming layer in the outside of water tank, to play function of heat insulation.The attemperater of this structure is in winter, Bei Fang winter especially, because of be cold, solar irradiation is penetrated partially, the sunshine-duration shortly is difficult to use hot water.Therefore, the solar water heater that also has takes electrically heated way to cover the shortage, and promptly sets up electrical heating elements in attemperater.But this mode is not only taken electricity increase cost but also dangerous (may leak electricity during water), and efficient is not high yet.
Summary of the invention
Technical problem to be solved by this invention is to overcome above deficiency, proposes a kind of can be incubated and can release heat, the heat-preserving water tank for solar water heater of high insulating effect.
For solving the problems of the technologies described above, a kind of heat-preserving water tank for solar water heater of the present invention comprises casing, described casing is provided with water inlet, delivery port and thermal-collecting tube socket, the tank wall of described casing is separated into two-layer, the internal layer of described tank wall is provided with the low melting point paraffin wax, and the skin of described tank wall is filled with foaming layer.
The present invention delivers to hot water in the attemperater when thermal-collecting tube owing to adopted above-mentioned technical pattern, and the temperature of water rises gradually in the attemperater.When on the water temperature in the water tank during to 90 ℃, the low melting point paraffin wax begins heat absorption fusing gradually.When paraffin wax all melted, its endothermic process was finished, and when by the time water temperature was lower than the temperature of low melting point paraffin wax, paraffin wax began release heat, and the hot water temperature in the incubator is prolonged, and had discharged and became solid type until the temperature of low melting point paraffin wax.Because the low melting point paraffin wax is heat absorption when the temperature of water is high in water tank, the release heat when temperature of water is low, like this, the time president that the water temperature in the water tank keeps is a lot, particularly just can use hot water in the winter time.Thereby the high insulating effect of heat-preserving water tank for solar water heater of the present invention, especially in the temperature retention time that can prolong in winter in the water tank.
Description of drawings
Fig. 1 is the structural representation of attemperater of the present invention;
Fig. 2 is the side direction structural representation with respect to Fig. 1.
The specific embodiment
As shown in the figure, a kind of heat-preserving water tank for solar water heater of the present invention comprises casing 7, and casing 7 is provided with water inlet, delivery port and thermal-collecting tube socket, is connected with water inlet pipe 4, outlet pipe 6 and vacuum heat collection pipe 1 respectively.The tank wall of casing 7 is separated into two-layer, and the internal layer of tank wall is provided with low melting point paraffin wax 3, and the skin of tank wall is filled with foaming layer 2, plays function of heat insulation.The inner chamber 5 of water tank is used to store water.In the use, when thermal-collecting tube 1 was sent hot water the inner chamber 5 of attemperater to, the temperature of water rose gradually in the attemperater, and low melting point paraffin wax layer 3 begins heat absorption and fusing gradually during to 90 ℃.When paraffin wax 3 all during fusing its heat absorption finish, when water temperature was lower than the temperature of low melting point paraffin wax by the time, paraffin wax began release heat, and the hot water temperatures in the attemperater inner chamber 5 are prolonged, and had discharged and became solid type until the temperature of low melting point paraffin wax 3.Because low melting point paraffin wax 3 is heat absorptions when the temperature of water is high in water tank, the release heat when temperature of water is low, the time president that the water temperature in the water tank keeps is a lot, thereby, even also can use hot water northerly winter.
