The main technical characteristic is that the flat plate solar collector with the defroster also comprises a defrosting unit, wherein the defrosting unit comprises a defrosting pressure-relief pipe, a piston, a spring and an end cover; and the piston is installed on the inner side of a water inlet at the front end of the defrosting pressure-relief pipe and moveably sealed with the defrosting pressure-relief pipe, the end cover is provided with a through hole and connected to the tail end of the defrosting pressure-relief pipe, the spring is installed in the defrosting pressure-relief pipe, and the defrosting unit is communicated with the header through the water inlet of the defrosting pressure-relief pipe. The flat plate solar collector with the defroster has the characteristics that a water pipe in the flat plate solar collector with the defroster can be prevented from being iced and spalled at lower ambient temperature, and the like.

Description

The flat-plate solar heat collector of band defroster

Technical field: the utility model relates to a kind of flat-plate solar heat collector with defroster.

Background technology: in the prior art, flat-plate solar heat collector is when environment temperature is low, and the water pipe in the flat-plate solar heat collector is because of the water freezing spalling in managing.Though the user can prevent bursting by freezing by manually discharging water, the user usually can forget and discharges water in actual the use, causes to exist the flat-plate solar heat collector inner water tube by defectives such as bursting by freezing.For overcoming these defectives, the flat-plate solar heat collector of band defroster is developed.

Summary of the invention: technical problem to be solved in the utility model is that a kind of flat-plate solar heat collector with defroster will be provided, and it can be effectively avoid water pipe in the flat-plate solar heat collector because of icing spalling when environment temperature is low.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises transparent cover plate, collector, comb, absorber plate, shell, collector and comb are communicated with and place in the shell with absorber plate is integrally welded, transparent cover plate places cover top portion, it also comprises antifreeze unit, described antifreeze unit comprises antifreeze relief tube, piston, spring, end cap, piston be installed in the inboard of antifreeze relief tube front end water inlet and with antifreeze relief tube movable sealing, end cap is provided with through hole, end cap is connected in the end of antifreeze relief tube, spring is installed in the antifreeze relief tube, and antifreeze unit is communicated with collector by the water inlet of antifreeze relief tube.

It also comprises sealing ring, and described sealing ring is enclosed within on the piston.

The end of described collector is equipped with antifreeze unit.

The sectional area of described antifreeze relief tube is more than or equal to the sectional area of collector.

The sectional area of described antifreeze relief tube is less than the sectional area of collector.

The utility model is compared the beneficial effect that is produced with background technology:

1, because the utility model adopts antifreeze unit, antifreeze unit comprises antifreeze relief tube, piston, spring, end cap, piston be installed in the inboard of antifreeze relief tube front end water inlet and with antifreeze relief tube movable sealing, end cap is provided with through hole, end cap is connected in the end of antifreeze relief tube, spring is installed in the antifreeze relief tube, the structure that the water inlet of antifreeze unit by antifreeze relief tube is communicated with collector is so it can avoid water pipe in the flat-plate solar heat collector because of icing spalling effectively when environment temperature is low.

Description of drawings: Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the annexation enlarged diagram of antifreeze unit 2 and collector 5 among Fig. 1.

Fig. 3 is the annexation explosive view of antifreeze unit 2 and collector 5 among Fig. 1.

Fig. 4 is the stereogram of Fig. 1.

Fig. 5 is the explosive view of Fig. 1.

The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, present embodiment comprises transparent cover plate 1, antifreeze unit 2, collector 5, comb 6, absorber plate 12, heat-barrier material 13, shell 14, collector 5 and comb 6 are communicated with, collector 5, comb 6, absorber plate 12 are integrally welded and place heat-barrier material 13 and be placed in the shell 14, and transparent cover plate 1 places shell 14 tops.

Antifreeze unit 2 comprises antifreeze relief tube 4, piston 7, spring 8, end cap 10, piston 7 is installed in the inboard of antifreeze relief tube 4 front end water inlets 3, and with antifreeze relief tube 4 movable sealings, end cap 10 is provided with through hole 11, sealing ring 9 is enclosed within on the piston 7, the quantity of sealing ring 9 can be more than one, as one, two, three, four etc., end cap 10 can be threadedly connected to the end of antifreeze relief tube 4, spring 8 is installed in the antifreeze relief tube 4, spring 8 two ends can be respectively and the interior side contacts of piston 7 and end cap 10, and antifreeze unit 2 is communicated with collector 5 by the water inlet 3 of antifreeze relief tube 4.In the present embodiment, antifreeze unit 2 is threadedly connected to the end of collector 5, is with a sealing ring 9 on the piston 7.

Antifreeze relief tube 4 sectional areas can less than, be equal to or greater than the sectional area of collector 5, in antifreeze relief tube 4, expand behind the water freezing in the antifreeze relief tube 4, when antifreeze relief tube 4 sectional areas during greater than the sectional area of collector 5, the effect of antifreeze pressure release is better, and antifreeze relief tube 4 sectional areas are greater than the sectional area of collector 5 in the present embodiment.

Collector 5 is when normal the use, the pressure of running water acts on the end face of piston 7 in the antifreeze unit 2, the piston 7 that promotes in the antifreeze unit 2 moves to end cap 10 directions, compression spring 8 reaches the dynamic balance on piston 7 both sides, at this moment antifreeze unit 2 is in poised state, the space that also has enough pistons 7 to move between piston 7 and close end cap 10 in the antifreeze relief tube 4.

When environment temperature is low, water freezing in the collector 5 in the water pipe solidifies, volume becomes big behind the water freezing, promote piston 7 extrusion springs 8, and move to the direction of end cap 10, the through holes 11 of the air in the antifreeze relief tube 4 from end cap 10 are discharged, and the part ice cube enters in the antifreeze relief tube 4, reduced greatly that ice cube is to the pressure of water pipe in the collector 5 after the water freezing volumetric expansion, the flat-plate solar heat collector inner water tube is because of the water freezing spalling in managing when avoiding environment temperature low.
