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 heat pipe solar water heater with shrinking and diverging nozzles. Background technique [0002] Solar water heater is a device that converts solar energy into heating, and heats water from low temperature to high temperature, so as to meet the hot water use in people's 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 conversion of solar energy mainly depends on the 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, part of the solar energy is not received by the heat collector, and the utilization rate of solar energy is not high. [0004] In order to reduce heat loss, vacuum tube solar water heaters are covered with vacu...
