Transversely inserted and close-spaced all-glass vacuum heat pipe combined heat-collecting pipe type solar collector

Abstract

The invention relates to a transversely inserted and close-spaced all-glass vacuum heat pipe combined heat-collecting pipe type solar collector, which comprises a water tank, all-glass vacuum heat pipe combined heat-collecting pipes, a fixing bracket and a propping tailstock. The liner of the water tank is provided with a water inlet and a water outlet, the water tank is vertically fixed on one end of the bracket, the same sides of the outer barrel, a heat insulation layer and the liner of the water tank is provided with holes with the same axis which are used for inserting the all-glass vacuum heat pipe combined heat-collecting pipes, or the water tank is vertically fixed in the middle of the bracket, two sides of the outer barrel, the heat insulation layer and the liner of the water tank are provided with holes with the same axis which are used for inserting the all-glass vacuum heat pipe combined heat-collecting pipes, the necking reducer pipe head is inserted in the seal ring on the pipe orifice of the liner, and the tail end of each all-glass vacuum heat pipe combined heat-collecting pipe is propped through the propping tailstock on the tail propping box of the bearing fixing bracket, thereby achieving the vertical and close-spaced arrangement of the all-glass vacuum heat pipe combined heat-collecting pipes. The invention improves the stability and the durability of the solar water heater, thereby achieving the perfect combination with the building. Moreover, the solar collector not only has the function of heat collecting, but also has the function of heat insulation and can be used as a building material.

Description

technical field [0001] The invention relates to a horizontally inserted and densely arranged all-glass vacuum heat pipe heat collecting tube solar heat collector, which is suitable for solar water heating systems with high requirements on stability performance and building combination. Background technique [0002] There are also some split pressure-bearing glass vacuum collector tube solar collectors on the market now, which are mainly divided into two types: 1. U-shaped tube collectors. 2. Heat pipe collector. The former U-shaped tube collector is also a medium in the metal tube through forced circulation heat exchange, the amount of copper tube is more, the welding requirements are higher, and the cost is also high. The latter type of heat pipe collector is through a vacuumed copper tube, which contains a heat transfer medium that vaporizes at high temperature and condenses at low temperature. Due to the large contact thermal resistance of the heat conducting fins of the...

Problems solved by technology

The latter type of heat pipe collector is through a vacuumed copper tube, which contains a heat transfer medium that vaporizes at high temperature and condenses at low temperature. Due to the large contact thermal resistance of the heat conducting fins of the heat pipe, the thermal efficiency of the whole machine is reduced.

Moreover, these two split pressure-bearing glass vacuum heat collecting tube solar collectors only have the function of heat collection, not heat preservation, nor building materials.
