Traditional solar water heater, its structure adopts with glass heat collection tube mostly and gathers sunshine, below the glass heat collection tube outer wall, concentrate and install reflector (sheet) additional, its objective is the heat that replenishes glass heat collection tube to the back partial reflection sunshine of glass heat collection tube, the transformation of glass heat collection tube is referring to shown in Figure 2, it is made up of interior pipe and outer tube, batch process for solar water heater, after producer arranges many glass heat collection tubes often, make the reflector (sheet) of an integral body according to the width of many glass heat collection tubes, perhaps the reflector (sheet) with integral body is made into corresponding with glass heat collection tube one by one arc, such structure has caused the cost increase of integral solar water heater and the waste of material, and reflector efficiency is low.

And the water tank of traditional solar water heater, its structure is that bucket appearance bread is carried out one deck insulation material in stainless mostly, and then install one deck corrosion resistant plate additional, the water that is heated by sunshine, can the transmission of part heat be distributed to insulation material through bucket in stainless, cause the heat loss of part.

And the water tank of a solar water heater design spout hole and steam vent above casing mostly, behind water tank waterborne full, will flow out from spout hole.It is safe that this structure is used under the state of temperature in spring, summer and autumn, spout hole can not have influence on the exhaust of steam vent, but to winter, if temperature is for a long time under the water freezing state, if use solar water heater, after waterborne expiring, arranged in the water tank, because cold weather, will stop up spout hole behind the water freezing and have influence on steam vent, will produce overflow in the water tank or exhaust is not smooth, cause the flat and bloated quick-fried phenomenon of suction of water tank easily, all bring some losses for user and production maintenance.

The above-mentioned defective that traditional solar water heater exists exerts a certain influence for applying of solar water heater.

Summary of the invention

Defective or deficiency at the existence of above-mentioned background technology, the purpose of this utility model is, a kind of light wave solar water heater is provided, this water heater has been done the many places improvement at glass heat collection tube, the water tank of traditional solar water heater, improved glass heat collection tube collecting efficiency and reduced the heat radiation of water tank and improved the water tank exhaust.

To achieve these goals, the utility model is taked following technical solution:

A kind of light wave solar water heater, the support, glass heat collection tube, reflector, the water tank that comprise conventional solar boilers, polyurethane insulation coating and one deck corrosion resistant plate are arranged on the water tank outer surface, and there are last exhaust outlet and side exhaust outlet in the top of water tank and side, the bottom is provided with intake-outlet; It is characterized in that described water tank bottom also is provided with the automatic overflow blast pipe, described reflector is arranged between the outer tube and interior pipe of glass heat collection tube.

Other characteristics of the present utility model are: also be coated with heat insulation coating between the outer surface of the stainless steel inner drum of described water tank and the polyurethane insulation coating, this heat insulation coating is selected from rare earth composite coating, ceramic powder paint, acrylic coating, polyurethane coating, granular polystyrene coating, zirconia coating, diatomite coating one or more compound wherein.

Described water tank bottom also is connected with an automatic overflow blast pipe that stretches in the water tank, this automatic overflow blast pipe upper end be shaped as groove, its groove position is lower than the position of side exhaust outlet of the side of water tank.

Described first heat insulation coating is strip or curve-like, and is evenly distributed on the staving, and its area is for covering more than 3/5ths of stainless steel inner drum surface.

Described polyurethane coating is stearic polyurethane or mono-composition poyurethane water-proof paint or elastomer coatings; Granular polystyrene coating is glue powder polyphenyl particle coating; Acrylic coating is an elastomeric propylene acid coating.

Described ceramic powder paint is a nanoscale.

The utility model is owing to directly install reflector additional between the outer tube of glass heat collection tube and interior pipe, the in-plant glass heat collection tube reflected sunlight of directly giving of this reflector, make glass heat collection tube moment generation high temperature, the experiment proved that, such structure can make the reflectivity of glass heat collection tube improve 26%, the thermal efficiency improves 7.2%, its heat insulation effect improves more than 20% than original water tank behind the coated heat-insulation layer of water tank, life-span prolongs 18%, the automatic overflow that installs additional in the water tank, blast pipe, when water level arrives automatic overflow, during the groove place of blast pipe, the water that surpasses the groove place will pass through this automatic overflow, blast pipe carries out overflow automatically, raise with limiting water level, because automatic overflow, the setting of the groove of blast pipe upper end is lower than the setting of exhaust outlet, does not influence the scavenging action of exhaust outlet.Can not make the exhaust of stopping up and having influence on steam vent when using in the winter time yet, can not cause the suction of water tank flat and bloated quick-fried.
