Description

Heat pipe joint

(1) technical field

The utility model relates to a kind of joint.Be the joint that heat collector on the solar water heater is subjected to be connected between boiler and the heat pipe usefulness specifically.

(2) background technology

At present, on the separated type solar water heater, its heat collector is subjected to the type of attachment between boiler and heat pipe, mainly contains bushing type, screw-type and direct insertion three kinds.Bushing type connects, and is a metal sleeve is the opening part that the sealing shape is fixed on water tank, and the heat conduction end of heat pipe directly inserts in the sleeve pipe, and the heat of heat pipe is transmitted to by its heat conduction end and sleeve pipe and is subjected in the boiler.Because in this connected mode, the heat of heat pipe need just can be transmitted to by the secondary conduction of heat conduction end and sleeve pipe and be subjected in the boiler, thermal losses is more, and the thermal efficiency is not high.Form is threaded, be at the heat conduction end root of heat pipe and be subjected in the perforate on the boiler on the circle threading and internal thread respectively, the heat conduction end of heat pipe is outer by this, internal thread directly screws in and is subjected in the perforate of boiler, makes direct insertion of heat conduction end of heat pipe be subjected to conduct heat in the boiler.Because this connected mode when mounted, whole heat pipe all will install the comparison difficulty with the screwing and rotate of its heat conduction end.Simultaneously, be threaded in the cold and hot effect that changes repeatedly drainage also easily takes place down.And direct insertion, then be one silica gel circle to be set at the tapping that is subjected to boiler, the heat conduction end of heat pipe directly is the insertion of sealing shape by this silica gel circle to be subjected in the boiler.Be subjected in the perforate of boiler because the heat conduction end of heat pipe is direct insertion of sealing shape, locate relatively difficulty during installation.When the pressure in being subjected to boiler raise with the rising of water temperature, loosening phenomenon can take place with the junction that is subjected to boiler in the heat conduction end of heat pipe, makes that the bearing capacity of joint is not strong.

(3) summary of the invention

The purpose of this utility model is to provide a kind of Heat pipe joint.Adopt this Heat pipe joint, can not only improve the thermal efficiency of heat pipe, and heat pipe and be subjected to the location and installation between boiler easy, also can avoid drainage to take place.

Above-mentioned purpose of the present utility model is realized by following technical solution:

Heat pipe joint of the present utility model comprises heat pipe and be subjected to boiler, and being subjected to has through hole on the sidewall of boiler.Be characterized in the heat conduction end root of heat pipe and be subjected to the through hole of boiler to be with adapter sleeve and elastic ring respectively.There is circumferential boss the adapter sleeve rear end.On the cylindrical of elastic ring circumferential recess is arranged, be subjected to embed in this circumferential recess around the through hole on the boiler.Circular diameter is less than the outside diameter of adapter sleeve in the said elastic ring, so that the heat conduction end of heat pipe makes sealing mutually between elastic ring and adapter sleeve after inserting in the elastic ring.Be with pressing plate on the heat pipe after the adapter sleeve, this pressing plate is a strip, and there is through hole at its two ends, is subjected to all to be fixed with nut on the upper and lower two sides of through hole of boiler, and the screw of two nuts is corresponding with the through hole at pressing plate two ends, and the two is fixed together by securing member.

Adopt such scheme, have the following advantages:

Because Heat pipe joint of the present utility model, the heat conduction end root of its heat pipe and be subjected to the through hole of boiler to be with adapter sleeve and elastic ring respectively, there is circumferential boss the adapter sleeve rear end, on the cylindrical of elastic ring circumferential recess is arranged, and is subjected to embed in this axial notch around the through hole on the boiler.Circular diameter is convenient to seal between elastic ring and adapter sleeve less than the outside diameter of adapter sleeve in the said elastic ring.The heat conduction end insertion that needs only during installation heat pipe is subjected in the perforate of boiler, and adapter sleeve is tightly offseted with elastic ring, just can realize being tightly connected of the two.Not only install easily, can also avoid the generation of drainage.Again because the heat pipe of this connected mode directly inserts is subjected in the boiler, directly contact with water in being subjected to boiler, thermal losses is less, thermal efficiency height.In addition, owing to be with pressing plate on the heat pipe after the adapter sleeve, this pressing plate is a strip, there is through hole at its two ends, be subjected to the through hole on the boiler all to be fixed with nut on the two sides up and down, the screw of this two nut is corresponding with the through hole at pressing plate two ends, and the two is fixed together by securing member.The bearing capacity of joint is strong.When the pressure in being subjected to boiler raises with the rising of water temperature, the heat conduction end of heat pipe and be subjected to also can not become flexible between the perforate of boiler.

(4) description of drawings

Accompanying drawing is a Heat pipe joint structural representation of the present utility model.

(5) specific embodiment

As shown in drawings, Heat pipe joint of the present utility model comprises heat pipe 1 and is subjected to boiler 4.The boiler 4 that is subjected to wherein is cuboid, and its cross section is rectangle (or square), and along being processed with through hole on the sidewall of its length direction, the quantity of this through hole is corresponding with the quantity of heat pipe 1, and each through hole all is provided with an elastic ring 3.Said elastic ring 3 is the silica gel circle, is processed with circumferential recess on its cylindrical, so as to be stuck in by this circumferential recess in the through hole that is subjected on boiler 4 sidewalls and with said through hole between sealing mutually.

The heat conduction end root of heat pipe 1 is provided with adapter sleeve 2, this adapter sleeve is that the hard material of metal one class is made, its be enclosed within the heat conduction end root and with heat conduction end root between be the sealing shape be connected mutually, its rear end outwards raises into circumferential boss 8, its leading portion diameter is greater than the interior circular diameter of elastic ring 3 and be processed with some arc grooves on the interior round Zhou Fangxiang of elastic ring 3, the heat conduction end of heat pipe 1 inserts in the through hole that is subjected on boiler 4 sidewalls and makes to be between justifying in adapter sleeve 2 leading portion cylindricals and the elastic ring 3 on it and closely cooperates, to realize the sealing of the two.

Be with a pressing plate 5 on the heat pipe 1 of (or claiming the outside) after adapter sleeve 2, this pressing plate is a strip, and its two ends are processed with through hole.All be welded with a nut 6 had on the two sides up and down of through hole by boiler 4, every pair of nut 6 is all corresponding with a pressing plate 5, and the two is fixed together by securing member 7.Thereby make 2 of elastic ring 3 and adapter sleeves, elastic ring 3 and be subjected to that homogeneous phase seals between through hole on boiler 4 sidewalls.
