Description

Heat exchanger with protective lining

Technical Field

The utility model relates to a heat exchange equipment field, especially a heat exchanger with protection bush.

Background

A heat exchanger in which copper tubes are sleeved with fins is widely used, and the heat exchanger has at least left and right support plates for mounting and fixing the heat exchanger in addition to the copper tubes and the fins. The left support plate and the right support plate are provided with pipe penetrating holes, and the copper pipe must penetrate through the pipe penetrating holes of the left support plate and the right support plate. Currently, the perforation holes have two structural types: a) a conical stretched flanging hole, b) a hole without flanging.

The above heat exchanger has drawbacks: the left and right supporting plates without the flanging holes have reduced rigidity, the left and right supporting plates are easy to deform integrally after being stressed, and the copper pipes are easy to damage by the peripheries without the flanging holes. The left and right supporting plates of the stretching flanging hole have increased rigidity, the left and right supporting plates are not easy to deform after being stressed, but the conical head-shaped stretching flanging hole is provided with an edge angle facing the copper pipe, so that the copper pipe is easy to be punctured.

Disclosure of Invention

The utility model aims at providing a heat exchanger with protection bush.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a heat exchanger with protection bush, its includes the support frame, wears to establish heat transfer copper pipe on the support frame, and the cover is established heat transfer fin on the heat transfer copper pipe, the support frame includes the backup pad of utensil through-hole, the heat transfer copper pipe certainly pass in the through-hole, it still including setting up the backup pad with tubulose bush between the copper pipe, the bush cover is established outside the heat transfer copper pipe, and the bush card is established in the through-hole.

Preferably, the bushing includes a circular tubular body and a catching portion directly enlarged outward from one end portion of the body.

Further preferably, the body portion passes through the through hole, and the locking portion is locked to one side of the through hole.

Preferably, the two support plates are arranged in parallel, the heat exchange copper pipes are arranged between the two support plates in a circuitous and penetrating manner, and the heat exchange fins are arranged between the two support plates.

Further preferably, the heat exchange fins disposed adjacent to the support plate are disposed against the bushing.

Further preferably, the through hole extends outward of the support plate in a conical tube shape.

Preferably, the bushing is a tubular rivet.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

because the utility model discloses a set up the bush at heat transfer copper pipe and backup pad support, backup pad and heat transfer copper pipe are not direct to be touched and wiped, can prevent that the backup pad from causing the harm to heat transfer copper pipe, can prolong the life of heat exchanger by a wide margin. Meanwhile, the clamping part of the bushing can play a role in auxiliary positioning, so that the bushing is convenient to install, and the installation efficiency is improved.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged schematic view of detail A of FIG. 1;

fig. 3 is a schematic structural diagram of another embodiment.

In the above drawings: 11. a left support plate; 12. a right support plate; 13. an upper top plate; 14. a lower base plate; 2. a heat exchange copper pipe; 3. heat exchange fins; 4. a bushing; 41. a body; 42. a clamping part; 5. and a through hole.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

referring to fig. 1-2, a heat exchanger with a protective bushing 4 comprises a left support plate 11, a right support plate 12, an upper top plate 13, a lower bottom plate 14, a heat exchange copper tube 2 which is arranged between the left support plate 11 and the right support plate 12 in a roundabout manner, a heat exchange fin 3 which is sleeved on the heat exchange copper tube 2, and a tubular bushing 4 which is arranged between the support plate and the heat exchange copper tube 2, so that the heat exchange copper tube 2 is prevented from directly contacting with the left support plate 11 and the right support plate 12, abrasion is reduced, and the service life of the heat exchange copper tube 2 is prolonged.

In this embodiment, the left support plate 11 and the right support plate 12 have through holes 5 extending outward in a conical tube shape, respectively. Referring to fig. 3, in other embodiments, the through holes 5 of the left support plate 11 and the right support plate 12 may be flat holes.

The bushing 4 comprises a tubular body 41 and a clamping portion 42 which is directly enlarged outwards from one end of the body 41, and the body 41 of the bushing 4 is sleeved on the heat exchange copper pipe 2 and penetrates through the through hole 5. Wherein, one side of the clamping part 42 of the bush 4 is clamped with the through hole 5, and the other side is propped against the heat exchange fin 3. When the bush 4 is tightly abutted against the heat exchange fins 3, the structure of the heat exchanger is more stable.

In this embodiment, the bushing 4 is a tubular rivet, and after the heat exchange copper pipe 2 expands, the bushing is tightly contacted with the inner wall of the tubular rivet and is not loosened. The tubular rivet is a standard component, which is readily available on the market, and the material of the tubular rivet can withstand the high temperatures of the subsequent welding process.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
