Summary of the invention
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of prevents leaking, the hot pipe type vacuum heat collection pipe of anti-bombing, good antiscale property.
The purpose of this utility model realizes by following technical measures: a kind of hot pipe type vacuum heat collection pipe, it include an end opening the glass outer tube, be equipped with the working medium that is used for exchange heat the metal heat-conducting pipe, be used for the elastic packing plug of the outer tube opening of seal glass, one end of metal heat-conducting pipe is an evaporation ends, the other end of metal heat-conducting pipe is a condensation end, the evaporation ends of metal heat-conducting pipe passes the elastic packing plug and is positioned at the glass outer tube, and in the glass outer tube is vacuum state, and the condensation end of metal heat-conducting pipe is positioned at outside the glass outer tube; Be provided with a caliber contraction place between the condensation end of metal heat-conducting pipe and the elastic packing plug.
Described glass outer tube is a glass round tube.
Described glass round tube is two glass heat collection tube plated film tubes.
Described elastic packing plug is a cylinder.
Described metal heat-conducting pipe is the copper pipe of strip.
The utility model beneficial effect is:
1, because the condensation end of metal heat-conducting pipe is the water tank that inserts solar water heater, and be provided with a caliber contraction place between the condensation end of metal heat-conducting pipe and the elastic packing plug, make the condensation end of metal heat-conducting pipe can be sealed in the water tank of solar water heater fully, like this, even the outer tracheal rupture of glass, water in the water tank can not flow out yet, thereby reaches anti-purpose of leaking;
2, because glass outer tube of the present utility model in use, does not need to flow into water, so, even glass outer tube of the present utility model is at high temperature, bombing can not occur yet, thereby reach the purpose of anti-bombing;
3, because glass outer tube of the present utility model in use, does not need to flow into water, so glass outer tube of the present utility model can not produce incrustation scale, thereby reach the purpose of good antiscale property yet, and can improve Heat-collecting effect.
Description of drawings
Fig. 1 is the structural representation of a kind of hot pipe type vacuum heat collection pipe of the utility model.
In Fig. 1, include:
1---glass outer tube 2---metal heat-conducting pipe
21---evaporation ends 22---condensation end
23---caliber contraction place 3---elastic packing plug
4---working medium.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of hot pipe type vacuum heat collection pipe of the present utility model, as shown in Figure 1, include the glass outer tube 1 of an end opening, metal heat-conducting pipe 2, the elastic packing plug 3 that is used for seal glass outer tube 1 opening, wherein, metal heat-conducting pipe 2 is a complete closed, and the working medium 4 that is used for exchange heat is housed in the metal heat-conducting pipe 2, one end of metal heat-conducting pipe 2 is an evaporation ends 21, the other end of metal heat-conducting pipe 2 is a condensation end 22, the evaporation ends 21 of metal heat-conducting pipe 2 passes elastic packing plug 3 and is positioned at glass outer tube 1, and in the glass outer tube 1 is vacuum state, the condensation end 22 of metal heat-conducting pipe 2 is positioned at outside the glass outer tube 1, glass outer tube 1 is that opening inclination is up placed in use, make the condensation end 22 of metal heat-conducting pipe 2 be higher than evaporation ends 21, when sunshine sees through the evaporation ends 21 of glass outer tube 1 irradiation metal heat-conducting pipe 2, can make the working medium 4 heating temperatures rising of the evaporation ends 21 in the metal heat-conducting pipe 2 and evaporate (i.e. vaporization), and evaporation rises to condensation end 22.
Be provided with a caliber contraction place 23 between the condensation end 22 of metal heat-conducting pipe 2 and the elastic packing plug 3, the caliber of condensation end 22 that is metal heat-conducting pipe 2 is bigger, after making that the condensation end 22 of metal heat-conducting pipe 2 inserts the water tank of solar water heaters, more or less freely sealing, like this, even glass outer tube 1 breaks, but the condensation end 22 of metal heat-conducting pipe 2 has been sealed in the water tank, so the water in the water tank can not flow out yet, thereby reach anti-purpose of leaking.
Glass outer tube 1 is a glass round tube, and glass round tube has cylindrical heat-absorbent surface, can accurately follow the tracks of sunshine, the utlity model has better Heat-collecting effect thereby make, certainly, described metal heat-conducting pipe 2 also can be made pipe, with the further Heat-collecting effect that improves; More particularly, described glass round tube is two glass heat collection tube plated film tubes, and this glass round tube has characteristics such as Heat-collecting effect is good, high temperature resistant; Described elastic packing plug 3 is a cylinder, and cylindrical elastic packing plug 3 can be close to the inwall of glass round tube, preferably the opening of seal glass pipe.
Metal heat-conducting pipe 2 is the copper pipe of strip, and copper pipe has heat conductivility preferably, certainly, described metal heat-conducting pipe 2 also can adopt other heat conductivility preferably material make, be not limited only to copper pipe.
The utility model in use, glass outer tube 1 tilted-putted angle (a) is greater than 10 degree, and promptly glass outer tube 1 and the angle of horizontal plane be greater than 10 degree, make the working medium 4 of the condensation end 22 of metal heat-conducting pipe 2 become liquid phase after, can rely on gravity reflux, return evaporation ends 21 again.At present embodiment, glass outer tube 1 tilted-putted angle is 45 degree, and its evaporation effect and backflow effect are all preferable, and certainly, described glass outer tube 1 tilted-putted angle also can be other angle, as long as it has preferable evaporation effect and backflow effect.
When the utility model is applied to solar water heater, the condensation end 22 of metal heat-conducting pipe 2 inserts and is sealed in the water tank of solar water heater, glass outer tube 1 then exposes, when sunshine sees through the evaporation ends 21 that glass outer tube 1 is radiated at metal heat-conducting pipe 2, the working medium 4 of the liquid phase of evaporation ends 21 is heated, temperature raises and evaporates the working medium 4 that becomes gas phase, and rise to condensation end 22 rapidly, the water that the working medium 4 of condensation end 22 gas phases sees through in metal heat-conducting pipe 2 and the water tank carries out exchange heat, promptly the water in the water tank is heated, after the working medium 4 process exchange heat and condensation of condensation end 22 gas phases, again become the working medium 4 of liquid phase, rely on gravity reflux again, return evaporation ends 21 again.Therefore, the utility model can utilize the vapour-liquid phase of a small amount of working medium 4 in the metal heat-conducting pipe 2 to become cyclic process, is heat energy with the conversion of solar energy that absorbs continuously, and the water in the water tank of solar water heater is heated.
