Horizontal type solar water heater

Abstract

The invention relates to a horizontal type solar water heater. One group of solar vacuum glass pipes on the exterior of a water storage tank is mutually communicated with one group of metal heat transfer pipes in the water storage tank to form a sealed loop, and heat conduction liquid is filled into the sealed loop. The solar water heater has the advantages that by using sunlight to heat the solar vacuum glass pipes and the heat conduction liquid, and utilizing the characteristics of liquid ascending by temperature rising and liquid descending by temperature lowering and the temperature difference between the interior of the water storage tank and the solar vacuum glass pipes, the heat conduction liquid circularly flows in the sealed loop to continuously heat the water in the water storage tank, and the metal heat transfer pipes also can quickly transfer the heat to heat the water, so the heat transfer efficiency is high; the water does not flow in the vacuum glass pipes, the sealing performance is good, the pipe explosion is avoided, and the vacuum glass pipes can run under the pressure condition; the water is completely isolated from a rubber ring and heat insulation material, the edible level sanitation is reached, and the purposes are expanded; a bracket is not required, the size is small, the weight is light, the cost is low, the transportation and the installation are convenient, the water heater can be directly arranged on the ground, the installation density is high, and the water heater can be conveniently hung on the wall; the capacity is very large, and the application range is greatly expanded; the structure is simple, the production and processing are realized by common technical equipment, the investment is little, the beginning is easy, and the period is short.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a horizontal solar water heater. Background technique [0002] The energy saving and environmental protection of solar energy product development and promotion are of great significance. The vacuum tube type solar water heater widely used at present, its solar vacuum tube is plugged on the water storage tank, water flows in the tube, the seal is poor, the antifreeze is poor, and it cannot operate under pressure. Convection only relies on the slow rise of the water in the tube after being heated and expanded, which is slow and inefficient. It adopts frame installation, which is large in volume and small in water tank, bulky, expensive in materials, complicated in structure and high in cost, inconvenient in processing, manufacturing, transportation and installation, unable to be wall-mounted, and the water body is not isolated from the apron and insulation materials, polluting the water bod...
