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...

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.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to an insulating water tank of a solar water heater. Background technique [0002] As we all know, solar water heaters are low-carbon, environmentally friendly, safe, and energy-saving appliances. Water heaters are used, so the insulation material of the water heater tank is directly related to the thermal efficiency and the use in the evening and early morning, especially in cold winter, the thermal insulation performance of the water heater tank directly affects the frequency and effect of solar water heater use. In a patent with the patent number 201220336344.6, the insulation layer of solar energy is combined with a vacuum layer and a polyurethane layer. The double-layer insulation has a good insulation effect, but because the polyurethane layer is relatively easy to deform, when the vacuum is drawn, the two sides of the polyurethane layer It is easier to deform und...
