The specific embodiment
As shown in Figure 1 and Figure 2, a kind of solar water heater described in the utility model comprises shell 1 and the endothermic water tank 2 who is fixedly mounted in the shell 1, and endothermic water tank 2 is provided with water inlet 3 and delivery port 4.Be filled with heat-insulation layer 8 between described endothermic water tank's 2 the following and shell 1, be coated with transparent warming plate above the endothermic water tank 2.In order to reduce cost, endothermic water tank 2 and shell 1 adopt plastic material, and certainly, in order to take into account the thermal efficiency simultaneously, endothermic water tank 2 material should be selected the good plastic material of heat absorption capacity for use.Transparent warming plate can adopt that light transmission is strong, glass plate with insulation effect or interlayer, insulating glass unit.So both can guarantee that light shone on the endothermic water tank 2, can prevent again that cross-ventilation from making endothermic water tank's 2 heat radiations.
In first embodiment, described endothermic water tank 2 comprises the many transverse tubes that be arranged in parallel 21 and the many longitudinal tubule (L tubule)s that be arranged in parallel 22, transverse tube 21 and longitudinal tubule (L tubule) 22 are in the same plane and connect with each other, and are being connected with muscle rib 24 between the outer wall of adjacent transverse tube 21 or between the outer wall of adjacent longitudinal tubule (L tubule) 22.Like this, transverse tube 21 and longitudinal tubule (L tubule) 22 interconnect becomes a platy structure, can accept irradiation of sunlight to greatest extent, helps improving the utilization rate of sunshine, can have higher voltage endurance capability again, can be used for pressure-bearing type solar water heater.And in endothermic water tank 2 inside, crisscross transverse tube 21 and longitudinal tubule (L tubule) 22 form a netted water system, can help heat exchange as soon as possible with the water heating.
Described transverse tube 21 and longitudinal tubule (L tubule) 22 all are that the cross section is circular pipe, and the axis of transverse tube 21 and longitudinal tubule (L tubule) 22 is wave, and transverse tube 21 intersects at the crest place or the trough place of axis with longitudinal tubule (L tubule) 22.Can in limited space, fully prolong the length of transverse tube 21 and longitudinal tubule (L tubule) 22 like this, not only increase heating surface area but also improved endothermic water tank's volume.
Be connected with auxiliary heating water tank 5 in endothermic water tank 2 lower end, the inside of auxiliary heating water tank 5 is equipped with electric heater 6, and the upper end of auxiliary heating water tank 5 is connected to the water inlet 3 that is positioned at endothermic water tank 2 lower ends by pipeline.
Employing endoporus connector is connected between auxiliary heating water tank 5 and the water inlet 3.As shown in Figure 3, Figure 4, described endoporus connector comprises connecting rod 7, by being threaded in the clamp nut 71 on the connecting rod 7, described connecting rod 7 is the tubulose of hollow, the fixedly connected taper expander of one end of connecting rod 7, the other end of connecting rod 7 has external screw thread, be set with elastomer 72 on the connecting rod 7 between taper expander and the clamp nut 71, described elastomer 72 is the pipe shape; The end that connecting rod 7 has a taper expander is installed in the inner chamber of auxiliary heating water tank 5 or in the water inlet 3, connecting rod 7 has an externally threaded end connecting pipe.
Elastomer 72 can adopt the stronger material manufacturings of elasticity such as rubber, plastics.Certainly, also can adopt copper, aluminium or elasticity, alloy material that ductility is good.
Have annular boss at clamp nut 71 towards a side of elastomer 72, the internal diameter of described annular boss, external diameter and elastomer 72 internal diameter, the external diameter under the non-stress state is suitable, promptly the diameter of this annular boss and wall thickness all equate with elastomer 72, perhaps in the scope that tolerance fit allows.The effect of this annular boss is better to compress elastomer 72, and can not be subjected to the interference of object on every side.
In addition, be set with stiffening ring 73 on connecting rod 7, the internal diameter of described stiffening ring 73 is greater than the external diameter of elastomer 72 under the non-stress state, and the external diameter of stiffening ring 73 is less than the external diameter of clamp nut 71.The effect of stiffening ring 73 is the steps on protecting on the thin-walled hole; because be used for the hole on the working of plastics such as water tank; usually in processing, can around the hole, increase the step of a projection; be used for strengthening the intensity of hole wall; stiffening ring 73 is enclosed within the outside of this step, can protect step can not be out of shape because of the extruding of clamp nut 71.
As shown in Figure 3, in the time of actual the use, the maximum outside diameter outline of the taper expander on the connecting rod 7 is less than the thin-walled hole on the auxiliary heating water tank 5 or the diameter of water inlet 3, makes it can just put the thin-walled hole into or water inlet 3 gets final product.But the difference of the maximum outside diameter of the diameter in thin-walled hole and taper expander can not be greater than the wall thickness of elastomer 72.Elastomer 72 under the non-stress state internal diameter and the external diameter of connecting rod 7 be complementary, the external diameter of elastomer 72 under the non-stress state is not more than the maximum outside diameter of taper expander at least, preferably equals the maximum outside diameter of taper expander.
As shown in Figure 4, stiffening ring 73 is enclosed within on the step of thin-walled hole or water inlet 3, the connecting rod 7 that will have elastomer 72 is put in the thin-walled hole, after elastomer 72 enters in the thin-walled hole fully, rotatably compress nut 71, promote elastomer 72 to lower slider by annular boss, because of elastomer 72 has certain elasticity, under the squeezing action of clamp nut 71, elastomer 72 can slide on the taper expander, this moment the taper expander maximum outside diameter add elastomer 72 wall thickness greater than the diameter in thin-walled hole, it can not be come off from the thin-walled hole.Continuing to rotatably compress nut 71 can be fixing with connecting rod 7.
After connecting rod 7 was fixed, the unnecessary threaded portion in clamp nut 71 upper ends can be used for connecting external pipeline.
Certainly,, in auxiliary heating water tank 5, be provided with the high temperature protection system, high temperature dry combustion method outage occurs for service life and the safety that guarantees electric heater.In order to prevent endothermic water tank's 2 overvoltages, at the water inlet end 11 of endothermic water tank 2 or auxiliary heating water tank 5 pressure-reducing valve 10 is installed, to guarantee the casing bearing capacity, water exit end is installed safety valve, occurs high pressure in the casing and in time discharges, and guarantees safety in utilization.
During use, endothermic water tank 2 outer wall can absorb the water heating that solar energy will be wherein, if temperature is not high enough, can also will assist water heating in the heating water tank 5 by electric heater 6, then with endothermic water tank 2 in the water convection current, produce and be fit to the hot water that uses.
During water, open valve, supply water to auxiliary heating water tank 5 by the water inlet end 11 that pressure-reducing valve 10 is installed, hot water is ejected, and discharges by the water channel and the safety valve that are connected on the delivery port 4, and is for people to use.
