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.
