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 p...

[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 o...
