Abstract
The utility model relates to a pressure bearing heat collector, which is characterized in that a metal barrel, in which a water inlet pipe can be inserted, is arranged in a double-layer vacuum glass pipe; the outer wall of the metal barrel is coated with selective absorption film. The utility model can be made into a heat storing vacuum pipe with a large diameter as required, and a water tank is not required to be arranged. When the utility model is made into a heat storing pipe with a small diameter, a plurality of the small heat storing pipes after connected in series or parallel can be connected with a water tank to form a pressure bearing water heater.
Description
The utility model relates to solar thermal energy and utilizes the field, relates in particular to a kind of pressure-bearing type heat collector.
Prior solar water heater, be to utilize solar thermal energy in the daily life at most with the most general, the maximum of the present usefulness of heat collector wherein mainly are vacuum glass heat collection tubes, its structure is the outer surface coating selective absorbing film of the double-layer glass tube inner layer glass that vacuumizes, pipe directly inserts water tank, or insert the very little column shape container-union pipe in cross section, and the maximum deficiency of this vacuum glass tube heat collector is can not pressure-bearing, and the hot water that water heater flows out is the little bathing poor effect of pressure often.
The purpose of this utility model provides a kind of pressure-bearing type heat collector, when dual-layer vacuum glass pipe diameter is big, as the heat accumulating type vacuum tube, water tank can be set no longer.
The purpose of this utility model is achieved through the following technical solutions, a kind of pressure-bearing type heat collector that vacuumizes double-layer glass tube that comprises, it is characterized in that the double glazing that vacuumizes glass tube is clear glass, glass tube is built-in with the metal drum of bottom lock, metal drum outer wall coating selective absorbing film in the glass tube, metal drum is welded with the water outlet interface, is inserted with water inlet pipe in the metal drum; The external diameter of metal drum is slightly less than the dual-layer vacuum glass bore; Water inlet pipe is inserted into the nearly bottom of metal drum, the junction seal welding of water inlet pipe and metal drum.
The utility model is by being provided with the metal drum of grafting water inlet pipe in glass tube with vacuum, this design makes cold water no longer directly enter in the glass tube with vacuum, but enter the metal drum of pressure-bearing by the water inlet pipe of pressure-bearing, the two-layer clear glass that is of glass tube with vacuum, the outer surface of inner layer glass tube no longer applies selective absorbing film, selective absorbing film is coated in the outer surface of the metal drum of pressure-bearing, thereby reduced in the original production process the raw-material waste that the fragmentation because of glass tube with vacuum causes, reduced production cost.The utility model can be made into major diameter as required simultaneously, and the utility model of this moment becomes the heat accumulating type vacuum tube, and water tank can no longer be set, and larger-diameter metal drum itself becomes the water tank of accumulation of heat; If it is less to be made into diameter, can be connected with water tank after the some connection in series-parallel, become pressure-bearing water heater.
Accompanying drawing 1 is the utility model structural representation.
In the accompanying drawing: the 1st, dual-layer vacuum glass pipe, the 2nd, metal drum, the 3rd, water inlet pipe, the 4th, absorbing film, the 5th, water outlet interface, the 6th, cushion rubber.
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the metal drum 2 of bottom lock is set in vacuumizing double-layer glass tube 1, be with cushion rubber 6 on the metal drum 2 of nearly dual-layer vacuum glass pipe 1 opening part, the upper end of metal drum 2 is provided with water outlet interface 5, insert water inlet pipe 3 in the metal drum 2, water inlet pipe 3 is inserted to the nearly bottom of metal drum 2, the junction seal welding of water inlet pipe 3 and metal drum 2, metal drum 2 outer walls coating selective absorbing film 4 in the dual-layer vacuum glass pipe 1, selective absorbing film 4 absorbs solar thermal energy and passes to metal drum 2, and metal drum 2 is passed to heat in the cold water that is entered by water inlet pipe 3.The utility model can be made into large diameter as required, and under large diameter situation, metal drum has become thermal storage type water tanks.
Claims (3)
1, a kind of pressure-bearing type heat collector that vacuumizes double-layer glass tube that comprises, it is characterized in that the double glazing that vacuumizes glass tube is clear glass, glass tube is built-in with the metal drum of bottom lock, metal drum outer wall coating selective absorbing film in the glass tube, metal drum is welded with the water outlet interface, is inserted with water inlet pipe in the metal drum.
2, pressure-bearing type heat collector according to claim 1 is characterized in that the external diameter of metal drum is slightly less than the dual-layer vacuum glass bore.
