Embodiment Construction
[0022] Such as figure 2 As shown, it is a schematic diagram of the connection between the header liner and the heat pipe of the present invention. The header liner 3 used in the present invention is a container with unlimited shapes, and the header liner 3 is covered with a layer of thermal insulation layer 2, and the outer shell 1 is covered with the thermal insulation layer 2 . The two ends of the header liner 3 are respectively water inlet and water outlet (not shown in the figure), and the water inlet and water outlet extend to the outside through the insulation layer 2 and the shell 1 . The water inlet is connected to tap water or other water sources with a certain pressure, and the water outlet is connected to hot water users.
[0023] In the present invention, one row or several rows of heat collecting tubes 5 are connected to the header liner 3, and the key points of the present invention are:
[0024] Such as figure 2 As shown, the header tank 3 is provided with ...

The invention relates to a sealing structure of a heat pipe type all-glass vacuum heat collector, which comprises a collecting box inner liner and a plurality of heat collecting tubes which are connected with the collecting box inner liner; wherein: the connecting box inner liner is provided with a pair of penetrated connecting holes to be corresponding to each heat collecting tube, a sealing ring is arranged in each connecting hole, and each sealing ring is fixed by an anti-extrusion part which is fixedly connected on the connecting box inner liner; the two ends of each heat collecting tube are sealed, and each heat collecting tube is provided with a neck part; each neck part penetrates the pair of the connecting holes and is connected with the anti-extrusion part in a sealing manner. As the water pressure in the connecting box inner liner does not act at the end parts of the heat collecting tubes, the heat pipe type all-glass vacuum heat collecting tubes can not be pushed out due to the action of the axial force of the liquid pressure in the connecting box inner liner under the situation of no external axial fixation, thus having low requirements on the strength of a connecting part for externally fixing the heat collecting tubes.
Description
technical field [0001] The invention relates to a pressure-bearing solar water heater, in particular to a heat pipe type all-glass vacuum pressure-bearing heat collector. Background technique [0002] The current forms of collectors are mainly divided into pressure-bearing type and non-pressure-bearing type according to whether they are under pressure or not during operation. [0003] In general, the vacuum heat collection tube of the non-pressure-bearing heat collector is inserted into the inner tank of the header, and is sealed by the compressibility and elasticity of the silicone rubber sealing ring, and the heat is collected by water or medium inside. Because the water inlet and outlet of the header liner are respectively connected with the non-pressurized water tank, and the water tank is provided with a water outlet pipe and an overflow pipe, the pressure when using water is determined according to the height difference between the water tank and the water tap. Due to...
