Abstract

The utility model discloses a thermal insulation solar water heater, comprising a supporting bracket, a water inlet, a water overflow port, an outer shell, an inner liner, a thermal insulation material layer, a water cavity. The supporting bracket is fixedly connected with the outer shell; the thermal insulation material layer is filled between the inner liner and the outer shell; the bottom and the surrounding of the inner liner is black, and the upper inclined plane of the inner liner is made of transparent material; a transparent covering board is parallel and fixedly arranged on the upper inclined plane of the inner liner; the space between the upper inclined plane of the inner liner and the transparent covering board forms into a hollow cavity, the transverse section of which is a inclined trapezoid because the lower part is narrow and the upper part is wide. The utility model has the advantages of high solar energy utilization ratio, simple structure, and low production cost.

Description

The heat preserving type solar water heater

Technical field:

The utility model relates to a kind of heat preserving type solar water heater that utilizes solar energy that water is heated.

Background technology:

Prior solar water heater is divided into two big classes by the heat absorption principle.The first kind is a closing-sunning type, temperature heat around irradiation of main dependence sunray or the utilization is conducted, come the water in the water heater is heated, plastics monotubular formula of Chu Shouing or multi-cartridge water heater all are this series products in the market, its shortcoming is that the cold cycling of water is slow, the efficient that absorbs solar energy is low, and heat time heating time is long, and temperature retention time is short.Second class is a heat collecting vacuum pipe formula solar water heater, it mainly is made of storage tank, heat collecting vacuum pipe, bracing frame etc., utilize heat collecting vacuum pipe to absorb solar energy, thereby to the heating that circulates of the water in the water tank, its advantage is the efficient height that absorbs solar energy, and shortcoming is complex structure, manufacturing cost height.

The utility model content:

The purpose of this utility model provides a kind of simple in structure, low cost of manufacture, heat preserving type solar water heater that absorption solar energy efficient is high.

To achieve these goals, the utility model comprises: bracing frame, water inlet, gap, shell, inner bag, adiabator layer, water cavity, bracing frame is fixedlyed connected with shell, adiabator layer is filled between inner bag and the shell, the inner bag bottom surface is a black around reaching, the ramp of inner bag is a transparent material, upper parallel at the inner bag ramp is set with transparent cover plate, make between the ramp of inner bag and the transparent cover plate and form cavity, the cross section of water cavity is one to tilt trapezoidally, and trapezoidal water cavity bottom is narrow and top is wide.

In use, can be fixed on the utility model on the house or the place of sunshine is arranged, make the scope of transparent cover plate towards the sunray irradiation, light will shine the inner bag surface of black equably by transparent cover plate and inner bag ramp like this, energy is evenly absorbed the water that also passes to rapidly in the water cavity by the inner bag of black, and water temperature is raise.Because the cross section of water cavity is that an inclination is trapezoidal, the bottom is narrow and top is wide, the water quick heating of bottom in the identical time, the water of higher temperature will rise automatically, and the water at low temperature on top will descend automatically, the formation microcirculation is flowed, accelerate to have improved solar energy utilization rate, and because the insulation material around the water cavity and the insulation effect of cavity, the time that hot water can keep long is for people to use, have characteristics such as simple in structure, low cost of manufacture.

Description of drawings:

Fig. 1 is an external structure schematic diagram of the present utility model.

Fig. 2 is the utility model horizontal section structural representation.

The specific embodiment:

By Fig. 1 Fig. 2 as can be known, the utility model comprises: bracing frame 1, water inlet 2, gap 4, shell 3, inner bag 6, adiabator layer 8, water cavity 9.Bracing frame 1 is fixedlyed connected with shell 3, adiabator layer 8 is filled between inner bag 6 and the shell 3, bracing frame 1 can adopt angle steel to be welded, and shell 3 can adopt fiberglass material or non-corrosive metal (NCM) material to make, and adiabator layer 8 can adopt blown polyurethane materials.The bottom surface of inner bag 6 is a black around reaching, and inner bag can adopt the black glass steel to process, so that the absorption of solar energy.The ramp 7 of inner bag is a transparent material, can adopt the transparent grp material, becomes overall structure by the bonding inner bag that makes.Upper parallel at inner bag ramp 7 is set with transparent cover plate 5, make between the ramp 7 of inner bag and the transparent cover plate 5 and form cavity, the cross section of water cavity 9 is one to tilt trapezoidally, and trapezoidal water cavity bottom is narrow and top is wide, so that the circulation of the absorption of solar energy and hot and cold water.For can a shared inlet and outlet pipe lines, be provided with water inlet 2 in the bottom of trapezoidal water cavity, it also can be used as delivery port and use, so that can thoroughly put water.Observation when gap 4 is used to be full of water and control.During actual installation, the gradient of water cavity can be decided according to the gradient of sunray, so that the black inner bag can absorb solar energy to greatest extent.
