Problems solved by technology

[0005] Although the flat-panel solar water heater is easy to install, the diameter of the pipe is small, the resistance is large, and most of them are made of aluminum alloy pipes, which are easy to corrode when the water quality cannot be guaranteed; In hot water above ℃), it is easy to generate scale and copper rust

Embodiment Construction

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] like figure 1 As shown in the figure, a heat pipe solar water heater with a tapered and expanding nozzle 4 includes a solar water tank 5, a bracket 6 and a collector 13. The lower part of the solar water tank 5 is connected to the collector 13. It consists of an incubator 7 , a glass cover 8 , a heat absorbing plate 9 , a phase change heat storage layer 10 , a thermal insulation layer 11 and a fixed seat 12 .

[0034] like figure 2 As shown, a plurality of heat collecting tubes 1 are arranged laterally inside the open incubator 7, such as image 3 As shown, the heat collecting pipe 1 is composed of a large heat pipe 2 and seven oscillating heat pipes 3. The upper end of the large heat pipe 2 is connected to the solar water tank 5 and is covered with a rubber sealing ring, as shown in the figure. Figure 8 As shown in the figure, the lower end o...

Abstract

The invention discloses a heat pipe solar water heater with a convergent-divergent nozzle. The heat pipe solar water heater comprises a solar water tank (5), a support (6) and a heat collector (13). The lower portion of the solar water tank (5) is connected with the heat collector (13), the heat collector (13) comprises heat-collecting tubes (1), an open warm-keeping box (7), a glass cover plate (8), heat-absorbing plates (9), a phase change heat storage layer (10) and a warm-keeping layer (11), and the multiple heat-collecting tubes (1) are transversely arranged inside the open warm-keeping box (7). The adopted hollow glass cover plate has the advantages of preventing heat conduction, convection heat exchange and long-wave radiation; the heat tubes have the characteristic of one-way heat transfer, so that heat will not be transferred in the opposite direction of gravity, and the heat loss of the solar water heater is greatly restrained on cloudy or rainy days.

Description

technical field [0001] The invention relates to the technical field of solar water heater equipment, in particular to a converging and expanding nozzle type heat pipe solar water heater. Background technique [0002] Solar water heater is a device that converts sunlight energy into heating, and heats water from low temperature to high temperature to meet people's hot water use in life and production. The vacuum tube solar water heater is composed of heat collecting tubes, water storage tanks and brackets and other related accessories. The solar energy is converted mainly by heat collecting tubes. water. [0003] The vacuum tube solar water heater is composed of several vacuum tubes, and there are gaps between the tubes. When exposed to sunlight, a part of the solar energy is not received by the collector, and the solar energy utilization rate is not high. [0004] In order to reduce heat loss, vacuum tube solar water heaters are covered with vacuum glass tubes. Vacuum glas...
