Solar hot water temperature gradient manifold

Abstract

The invention relates to a solar hot water temperature gradient manifold. The solar hot water temperature gradient manifold is designed according to the fluid thermodynamic temperature gradient principle. The solar hot water temperature gradient manifold is used for enabling hot water to carry out flow division according to a certain gradient temperature, and is arranged between two solar water tanks with the temperature grade difference. The solar hot water temperature gradient manifold comprises a long pipe, a short pipe and a connecting pipe, wherein the long pipe is arranged in the solar water tank with the lower water temperature, and the tail end of the long pipe is arranged on the upper portion of the solar water tank; the short pipe is arranged in the solar water tank with the higher water temperature, and the tail end of the short pipe is arranged on the lower portion of the solar water tank; the long pipe is connected with the short pipe through the connecting pipe. The solar hot water temperature gradient manifold has the advantages that hot water on the upper layer of the solar water tank with the lower water temperature can be conveyed to the solar water tank with the higher water temperature, and conveying flow of the hot water, with the higher temperature, between multi-level heating water tanks is quickened. The solar hot water temperature gradient manifold is simple in structure, snap rings and silica gel elbows can be freely disassembled, and cleaning is convenient; due to the fact that anti-bacterial layers are arranged on the inner wall of the long pipe, the inner wall of the short pipe and the inner wall of the connecting pipe respectively, bacteria breeding is reduced, and water quality is ensured.

Description

technical field [0001] The invention relates to the technical field of connecting pipelines, in particular to a solar hot water temperature gradient shunt pipe. Background technique [0002] Solar water heaters have been widely promoted and applied. Existing solar water heaters mainly consist of vacuum heat collecting tubes, heat preservation water storage tanks and supports. The water storage tank is a single water tank structure. Lead out from the upper part of the water storage tank. It uses vacuum heat collecting tubes to absorb solar energy, and then conducts heat exchange with the water storage tank, and finally achieves the purpose of heating water, but due to the limitation of solar energy collection efficiency, it is difficult for the hot water in the water storage tank to quickly meet the use requirements, resulting in a kind of Hot water system with multi-stage (heating) tanks. However, the connecting pipes between existing solar multi-stage water tanks are simp...

It uses vacuum heat collecting tubes to absorb solar energy, and then conducts heat exchange with the water storage tank, and finally achieves the purpose of heating water, but due to the limitation of solar energy collection efficiency, it is difficult for the hot water in the water storage tank to quickly meet the use requirements, resulting in a kind of Hot water system with multi-stage (heated) tanks

However, the connecting pipes between existing solar multi-stage water tanks are simply connected, because the temperature between different water tanks is the same, so the simple connection of multi-stage (heating) is no different from the overall water tank, and it is difficult to make hot water flow quickly to the hot water tank. Water requires a water outlet for use. Normally, the connecting pipe cannot be disassembled. After long-term use, there will be a lot of dirt in the connecting pipe, making it difficult to clean
