Referring to fig. 1 and 2, the present utility model provides a gasket for a heat exchanger for receiving a heat exchange tube, the gasket comprising:
the filler strip body 100, the filler strip body 100 has been offered and has been accepted groove 110, vortex hole 120, cavity 130, accepts the groove 110 and offered along the axis interval of filler strip body 100, accepts the groove 110 and supports the heat exchange tube, and the heat exchange tube part is located cavity 130, and vortex hole 120 intercommunication cavity 130.
In the technical scheme adopted in the embodiment, the cavity 130 and the turbulent flow hole 120 are formed in the filler strip body 100, the turbulent flow hole 120 is communicated with the cavity 130, the contact area between a heat exchange medium in a heat exchange shell and the heat exchange tube is increased, the heat exchange efficiency is improved, and the technical problem that the heat exchange tube and the heat exchange medium in the heat exchange shell are isolated by the filler strip for the current heat exchanger is solved. The receiving groove 110 is used for supporting a heat exchange tube, when a heat exchange medium flows through the disturbing hole 120, the heat exchange medium can flow into the cavity 130 through the disturbing hole 120, and because the heat exchange tube is partially positioned in the cavity 130, the heat exchange medium can exchange heat with the heat exchange tube when entering the cavity 130, and the flowing direction of the heat exchange medium can be changed when flowing through the disturbing hole 120, so that a disturbing effect is generated, the disturbing effect can bring two benefits, namely, the occurrence of a heat exchange dead zone is reduced, and scaling is further reduced; and secondly, the heat exchange efficiency is improved.
In addition, the receiving groove 110 and the spoiler hole 120 are integrally punched. Referring to fig. 2 and 3, after the filler strip is developed into a planar structure, it can be seen that the receiving groove 110 and the turbulence hole 120 can be directly formed by punching a plate through a punching machine, and the plate can form the structures of the receiving groove 110, the cavity 130, the folded edge 140 and the like through bending after the punching is completed. The cross section shape of the bent backing strip is omega-shaped, and the structure is more balanced in stress.
When the length of a single filler strip cannot meet the requirements of the heat exchange tube, a plurality of filler strips can be spliced end to end and connected by welding or other modes to meet the requirements of different lengths.
Further, the spoiler holes 120 have an oblate shape.
In the technical solution adopted in this embodiment, the oblate-shaped turbulence hole 120 is a preferred shape of the turbulence hole 120, and the turbulence hole 120 may also be selected as a diamond shape, a round shape, or the like, and compared with the shapes of these angular structures such as a diamond shape, the round and oblate-shaped structures can make the heat exchange medium smoother in flowing, and the heat exchange dead zone is easy to occur at the angular structure. The oblate shape is preferably an oblate shape because a larger area can be opened in the same radial width range than the circular shape, and the number of punching times can be reduced during processing.
Further, the edge of the filler strip body 100 is folded to form a folded edge 140. By providing the flaps 140, the overall stability of the filler strip is improved.
Specifically, the spoiler holes 120 are spaced apart along the fold line 150 and are symmetrical about the fold line 150. The turbulence holes 120 are symmetrical with the bending lines 150, that is, the turbulence holes 120 are also bent, and the shape of the turbulence holes 120 becomes irregular after bending, so that a better turbulence effect can be achieved.
Further, referring to fig. 5, the side of the receiving groove 110 forms a predetermined angle a with the radial straight line of the filler strip body 100.
In the technical scheme adopted in the embodiment, by setting the angle a, the receiving groove 110 is inclined by a certain angle when the receiving groove 110 is overlooked, so that the fitting winding tube type heat exchanger is facilitated, and the specific angle a can be determined according to the bending angle when the heat exchange tube is wound.
In addition, in order to facilitate the placement of the heat exchange tube, the width L of the receiving groove 110 needs to be slightly larger than the tube diameter of the heat exchange tube, and a specific value of the width L is determined according to a specific tube diameter.
Further, referring to fig. 4, the gasket strip further includes an elastic pad 200, and the elastic pad 200 is disposed at the edge of the receiving groove 110.
In the technical solution adopted in this embodiment, since the width L of the receiving groove 110 is slightly larger than the pipe diameter of the heat exchange pipe, the heat exchange pipe may shake in the receiving groove 110, and thus the elastic pad 200 is disposed at the edge of the receiving groove 110. On the one hand, as the filler strips and the heat exchange tubes are made of metal materials, the heat exchange tubes are scratched mutually due to shaking in the receiving groove 110, and finally the tube wall of the heat exchange tube is thinned, the shape of the receiving groove 110 is deformed, and the elastic pad 200 is arranged to avoid direct contact of the filler strips and the heat exchange tubes; on the other hand, the heat exchange tube can be more stably arranged in the receiving groove 110 by the elastic deformation of the elastic pad 200.
Further, the filler strip further includes a spoiler protrusion 300 and/or a spoiler groove 400, and the spoiler protrusion 300 and/or the spoiler groove 400 are disposed on the surface of the filler strip body 100.
In the technical solution adopted in this embodiment, the turbulence protrusions 300 and/or the turbulence grooves 400 are provided on the surface of the filler strip body 100, so that the surface of the filler strip becomes uneven, turbulence is generated on the heat exchange medium flowing through the surface of the filler strip body 100, and the heat exchange efficiency is improved through the turbulence.
Further, the spaces between the receiving grooves 110 are the same, so that the force applied to the filler strip body 100 is more balanced, and the filler strip is not easy to deform.
The utility model also provides a heat exchanger, which comprises the filler strip for the heat exchanger, and the specific structure of the filler strip refers to the embodiment, and the heat exchanger has at least all the beneficial effects brought by the technical scheme of the embodiment because the heat exchanger has the filler strip structure, and the detailed description is omitted.
The foregoing description of the embodiments of the present utility model is merely an optional embodiment of the present utility model, and is not intended to limit the scope of the utility model, and all equivalent structural modifications made by the present utility model in the light of the present utility model, the description of which and the accompanying drawings, or direct/indirect application in other related technical fields are included in the scope of the utility model.
