Problems solved by technology

[0002] Most of the existing solar water heaters are non-pressurized, and their heat collecting tubes are straight tubes, and the connection with the water heater tank is only sealed by rubber rings, which cannot withstand a certain water pressure, and the heat transfer is slow, the heat loss is large, and the water flow speed is slow. The water stored in the pipes cannot be fully utilized every day
The heat collecting tube cannot be directly used in the pressurized solar heat collecting system, and it is inconvenient to be integrated with the building. It is only limited to the in-line non-pressure solar water heater.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] figure 1 As shown in the figure, the "L"-shaped plug-in guide tube 9 connects several large-diameter glass vacuum heat collector tubes 4 in series to form a heat collector. The guide tube of the first heat collector tube is connected to the cold water inlet pipe 5, and the cold water inlet pipe is installed There is a check valve 6 and a pressure switch valve 7. The diversion pipe of the heat collecting pipe at the end is connected to the hot water outlet pipe 1, and a pressure relief safety valve 3 is connected in series to the hot water outlet pipe, and any one of the first to fourth at the end A temperature sensor 21 is inserted in the heat collecting tube, and the two ends of the heat collector are installed on the joint box 8 respectively. The glass vacuum heat collecting tube 4 is provided with a self-controlled low-power electric heater 2...

Abstract

The present invention relates to an all-weather pressure-bearing type solar water heater free from water tank. It includes heat collector which is made up by series-connecting several glass evacuated collecting tubes by means of L-shaped flow-inducing tubes, on the cold water inlet tube of first collecting tube a non-return valve and a pressure switching valve are set, on the hot water outlet tube of tail end collecting tube a decompression safety valve is series-connected, and a temperature sensor is inserted into any one collecting tube of tail portion first to fourth collecting tube. Said solar water heater has the double function of heat collection and water storage.

Description

technical field [0001] The invention relates to a solar water heating device, in particular to a photoelectric integrated all-weather water tankless pressurized solar water heater. Background technique [0002] Most of the existing solar water heaters are non-pressurized, and their heat collecting tubes are straight tubes. The connection to the water heater tank is only sealed by rubber rings, which cannot withstand a certain water pressure, and the heat transfer is slow, the heat loss is large, and the water flow speed is slow. The water stored in the pipe cannot be fully utilized every day. The heat collecting tube cannot be directly used in a pressurized solar heat collecting system, and it is inconvenient to be integrated with the building. It is only limited to the direct plug-in non-pressure solar water heater. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an all-weather tankless ...
