Solar heat collecting pipe anti-burst device and solar water heater

Abstract

The invention provides a solar heat collecting pipe anti-burst device. The solar heat collecting pipe anti-burst device comprises a temperature sensor arranged in a heat collecting pipe and a controlstructure which is arranged at a water inlet and outlet pipe head and used for sealing and opening the water inlet and outlet pipe head, the control structure is connected with the temperature sensor,when the value of the temperature in the heat collecting pipe is larger than the set temperature value of the temperature sensor, the control structure is used for sealing the water inlet and outletpipe head, when the value of the temperature in the heat collecting pipe is smaller than the set temperature value of the temperature sensor, the control structure is used for opening the water inletand outlet pipe head, the water inlet and outlet pipe head is arranged on a heat preservation water tank, the heat preservation water tank communicates with the heat collecting pipe, and a solar waterheater adopts the solar heat collecting pipe anti-burst device. According to the solar heat collecting pipe anti-burst device and the solar water heater, burst of the heat collecting pipe can not occur whenever water is supplemented, so that the use is safe, and prolonging of the service life is facilitated.

Description

technical field [0001] The invention belongs to the technical field of light-to-heat conversion, and more specifically relates to a solar heat collection tube anti-explosion device and a solar water heater using the solar heat collection tube anti-explosion device. Background technique [0002] In recent years, solar energy has been actively developed and utilized as a clean energy source, and it has also been actively developed and utilized in the use of solar water heating, especially the household vacuum glass heat collecting tube (the vacuum glass heat collecting tube is referred to as heat collecting tube for short) solar water heater. It is popularized and used in small and medium-sized cities and vast rural areas in my country, but this kind of solar water heater has a major disadvantage. The phenomenon of tube explosion occurs from time to time when users use it. The reason for the tube explosion is that household solar water heaters collect When the heat pipe is short...
