Description

Ground-coupled heat exchanger heat exchange tube structure

Technical field

It the utility model is related to a kind of ground-coupled heat exchanger heat exchange tube structure.

Background technology

Ground-coupled heat exchanger uses PE pipe structures more with heat exchanger tube in existing technology, its defect is that heat exchange efficiency is low, is changed Hot area is small.

The content of the invention

Problem to be solved in the utility model is to provide a kind of ground-coupled heat exchanger heat exchange tube structure, overcomes the prior art In deficiency.

In order to solve the above technical problems, the technical solution adopted in the utility model is：Ground-coupled heat exchanger heat exchange tube structure, Including multiple end to end unit tube bodies, the inner wall of the unit tube body has one section of inner conical surface, institute close to endface thereon State inner conical surface be located at the unit tube body upper end surface internal diameter it is larger, it is uniformly distributed more around its axis on the side wall of the unit tube body A metal heat-conducting fin, the inner of the metal heat-conducting fin are located at the unit tubular body, and the unit pipes are stretched out in outer end Outside the outer wall of body, the outer wall of the unit tube body has one section of male cone (strobilus masculinus) at its lower end, and the male cone (strobilus masculinus) is positioned at described Outside diameter at unit bottom of the pipe is smaller, and the outside diameter that the male cone (strobilus masculinus) is located at the unit bottom of the pipe is more than the inner conical surface Upper less internal diameter, less than the internal diameter being located on the inner conical surface at the unit tube body upper end, the top layer disk of the male cone (strobilus masculinus) Around electric fuse, one end stretching unit pipes of the electric fuse are external, and have power connection.

Further, the inner wall of the unit tube body, which is located at the inner conical surface internal diameter smaller part, has cut-off land.

Further, the metal heat-conducting fin is the arc metal plate bent downward.

The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme, it is reasonable in design, energy Heat exchange area and heat exchanger effectiveness is significantly increased, it is more convenient to use；It is easy to maintenance with simple in structure, processing cost is low, The advantages that production efficiency is high.

Embodiment

As shown in Figure 1, the utility model provides a kind of ground-coupled heat exchanger heat exchange tube structure, including it is multiple end to end Unit tube body 1, the inner wall of unit tube body 1 have one section of inner conical surface 4 close to endface thereon, and inner conical surface 4 is located on unit tube body 1 The internal diameter of endface is larger, and multiple metal heat-conducting fins 2, metal heat-conducting fin 2 are evenly distributed with around its axis on the side wall of unit tube body 1 The inner be located inside unit tube body 1, outer end is stretched out outside the outer wall of unit tube body 1, and the outer wall of unit tube body 1 is close to its lower end Place has one section of male cone (strobilus masculinus) 5, and the outside diameter that male cone (strobilus masculinus) 5 is located at 1 lower end of unit tube body is smaller, and male cone (strobilus masculinus) 5 is located under unit tube body 1 Outside diameter at end is more than less internal diameter on inner conical surface 4, less than the internal diameter being located on inner conical surface 4 at 1 upper end of unit pipes body, outer cone The top layer coiling electric fuse 6 in face 5, one end of electric fuse 6 is stretched out outside unit tube body 1, and has power connection（Do not show in figure）.

In said structure, seal against each other connection by multiple unit tube bodies 1 and form whole tube body, wherein metal heat-conducting fin 2 play the role of increasing heat transfer area and heat transfer efficiency, and the number of connection unit tube body 1 is determined according to the length of required tube body, Connection sealing means between adjacent cells tube body 1 are：By one end with male cone (strobilus masculinus) 5 be inserted into another unit tube body 1 with In the tube body of inner conical surface 4, after extraneous power supply is powered, the heating of electric fuse 6 melts the surface of male cone (strobilus masculinus) 5, at this time to unit tube body 1 Force, makes 5 one sections of male cone (strobilus masculinus) stretch into 4 sections of inner conical surface, since the thawing on 5 surface of male cone (strobilus masculinus) causes it in progradation is extruded Deform, bonding can be sealed against each other by the surface of male cone (strobilus masculinus) 5 and with the inner wall of inner conical surface 4 after cooling.

The inner wall of unit tube body 1, which is located at 4 internal diameter smaller part of inner conical surface, has cut-off land 3.Cut-off land 3 is arranged on limit 5 one sections of inner conical surface processed continue promote while, the materials in the tube of thawing can be also deposited at inner conical surface 4, avoid melt materials in the tube to Lower loss, makes melt bonded effect be deteriorated.

Metal heat-conducting fin 2 is the arc metal plate bent downward.The structure setting of arc metal plate can increase metal wing The area of piece, while reduce occupied space axial outside tube body.

The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model Embodiment, it is impossible to be construed as limiting the scope of the utility model.It is made according to the scope of application of this utility model equal Deng change and improvement etc., should all still belong within the patent covering scope of the utility model.
