Method used

The invention provides a kind of solar water heater, embodiment 1 as shown in Fig. 1, Fig. 2 and Fig. 3, comprises insulation water tank, and insulation water tank is arranged successively from inside to outside with inner bag 1 that stainless steel is made, polyurethane insulation Layer 2 and the water tank shell 3 made of color steel plate. The outer wall of the inner tank 1 is provided with four baffles 4 surrounding the inner tank 1. The baffles 4 are provided with a number of through holes 5. The inner tank 1 and the polyurethane insulation layer A vacuum layer 6 is formed between the two, and the outer side of the polyurethane insulation layer 2 is closely bonded to the water tank shell 3. The setting of the baffle plate 4 in this embodiment can reduce the deformation of the polyurethane insulation layer 2, and the through hole 5 provided on the baffle plate 4 can facilitate vacuuming.

Abstract

The invention provides a solar water heater. The solar water heater comprises an insulation water tank, wherein the insulation water tank consists of a liner, a polyurethane insulation layer and a water tank shell connected in sequence from inside to outside; a baffle plate surrounding the liner is arranged on the outer side wall of the liner, and is provided with multiple through holes; a vacuum layer is formed between the liner and the polyurethane insulation layer; and the outer side of the polyurethane insulation layer is tightly bonded with the water tank shell. On the one hand, the solar water heater adopts the vacuum layer and the polyurethane insulation layer for insulation to achieve the better insulation effect; and on the other hand, the baffle plate arranged on the outer wall of the liner effectively prevents the deformation of the polyurethane insulation layer; moreover, the water tank shell tightly bonded at the outer side of the polyurethane insulation layer prevents direct exposure of the polyurethane insulation layer under sunlight, so that the service life of the solar water heater is prolonged; and the solar water heater has such advantages as simple structure, low machining cost and good insulation effect.

Example Embodiment

[0022] Example 1
[0023] The invention creates a solar water heater, embodiment 1 is as figure 1 , figure 2 and image 3 As shown, it includes a heat preservation water tank. The heat preservation water tank is provided with an inner tank made of stainless steel 1, a polyurethane insulation layer 2 and a water tank shell 3 made of color steel plates from the inside to the outside. The outer wall of the inner tank 1 is provided with 4 surrounds The baffle 4 of the inner tank 1 is provided with a plurality of through holes 5 on the baffle 4, a vacuum layer 6 is formed between the inner tank 1 and the polyurethane insulation layer 2, and the outer side of the polyurethane insulation layer 2 is tightly bonded with the water tank shell 3. The arrangement of the baffle 4 in this embodiment can reduce the deformation of the polyurethane insulation layer 2, and the through holes 5 provided on the baffle 4 can facilitate vacuuming. The arrangement of the water tank shell 3 effectively protects the polyurethane insulation layer 2, prevents the polyurethane insulation layer 2 from being directly exposed to the sun, and improves the insulation performance and service life of the solar water heater. The double-layer insulation of the vacuum layer 6 and the polyurethane insulation layer 2 has a better insulation effect.

Example Embodiment

[0024] Example 2
[0025] The invention creates a solar water heater, embodiment 2 is as Figure 4 , Figure 5 and Image 6 As shown, it includes a heat preservation water tank. The heat preservation water tank is provided with an inner tank made of stainless steel 1, a polyurethane insulation layer 2 and a water tank shell 3 made of aluminized zinc plate from the inside to the outside. The outer wall of the inner tank 1 is provided with 10 A baffle 4 surrounds the inner tank 1. A number of through holes 5 are provided on the baffle 4. A vacuum layer 6 is formed between the inner tank 1 and the polyurethane insulation layer 2. The outer side of the polyurethane insulation layer 2 is tightly bonded to the water tank shell 3. The inner side of the insulation layer 2 is connected with a 0.5 mm thick stainless steel plate layer 7, and the vacuum layer 6 is connected to the outside atmosphere through a vacuum hole 8 and a sealing plug is filled in the vacuum hole 8. The arrangement of the baffle 4 in this embodiment can reduce the deformation of the polyurethane insulation layer 2, and the through holes 5 provided on the baffle 4 can facilitate vacuuming. The arrangement of the water tank shell 3 effectively protects the polyurethane insulation layer 2, prevents the polyurethane insulation layer 2 from being directly exposed to the sun, and improves the insulation performance and service life of the solar water heater. The double-layer insulation of the vacuum layer 6 and the polyurethane insulation layer 2 has a better insulation effect. The stainless steel plate layer 7 is a protective layer, and the stainless steel plate layer 7 prevents the polyurethane insulation layer 2 from directly contacting the baffle 4, thereby dispersing the pressure on various points of the polyurethane insulation layer 2 and further reducing the deformation of the polyurethane insulation layer 2. The setting of the vacuum hole 8 can vacuum the vacuum layer 6 after the solar water heater is used for a period of time, so that the vacuum layer 6 meets the vacuum requirement, so as to achieve the effect of heat preservation.
