Abstract
The invention relates to a seal structure for a heat exchanger. The seal structure comprises a seal which is of a long-strip-shaped structure. A side wall of the seal is provided with a plurality of arc-shaped grooves, the other side wall of the seal, the upper side wall of the seal and the lower side wall of the seal are respectively provided with a plurality of square grooves, and the middle of the seal is provided with through holes. The seal structure for the heat exchanger is reasonable in structure, convenient to manufacture and low in cost. In the seal assembly process, due to the effect of the square grooves, welding seam gaps are controlled, and weldability of the seal structure is good.
Description
Technical field
The present invention relates to the heat transmission equipment technical field, especially a kind of heat exchanger seal structure.
Background technology
Heat exchanger, claim again heat exchanger, heat passed to the device of another kind of heat-carrying agent from a kind of heat-carrying agent.In industrial processes, usually need to heat or cooling the i.e. transmission of heat.When a kind of fluid and one other fluid are carried out heat exchange and are not allowed to mix, just require to carry out in recuperative heat exchanger, be applied to the industries such as chemical industry, oil, power, food. the Main Function of heat exchanger is thermal energy exchange between cold fluid and hot fluid.
At present, plate-fin heat exchanger is generally applied, plate-fin heat exchanger mainly comprises dividing plate, fin, strip of paper used for sealing and flow deflector, and strip of paper used for sealing is one of critical piece in plate-fin heat exchanger, the quality of its quality directly affects quality and the life-span of plate-fin heat exchanger, its complex structure of strip of paper used for sealing of the prior art, make trouble, and cost is high.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of heat exchanger seal structure rational in infrastructure, thereby simplifies seal structure, and is easy to make, reduces costs, and solderability is high.
The technical solution adopted in the present invention is as follows:
A kind of heat exchanger seal structure, comprise strip of paper used for sealing, and described strip of paper used for sealing growth strip structure, have many circular grooves on a sidewall of described strip of paper used for sealing, is positioned on another sidewall of strip of paper used for sealing and top and bottom sidewall and has many square grooves; Described strip of paper used for sealing middle part has through hole.
As further improvement in the technical proposal:
The cross section of described strip of paper used for sealing is rectangle structure;
The cross section of described strip of paper used for sealing is square structure;
Have the circular groove of two parallel interval on one sidewall of described strip of paper used for sealing;
Have the square groove of three parallel interval on another sidewall of described strip of paper used for sealing and top and bottom sidewall.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, easy to make, cost is low, and strip of paper used for sealing in assembling process,, due to the effect of square groove, is controlled weld gap, and its solderability is good.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, square groove; 2, through hole; 3, circular groove.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the heat exchanger seal structure of the present embodiment, comprise strip of paper used for sealing, and strip of paper used for sealing growth strip structure has many circular grooves 3 on one sidewall of strip of paper used for sealing, is positioned on another sidewall of strip of paper used for sealing and top and bottom sidewall and has many square grooves 1; The strip of paper used for sealing middle part has through hole 2.
The cross section of strip of paper used for sealing is rectangle structure.
The cross section of strip of paper used for sealing is square structure.The cross sectional shape of strip of paper used for sealing can be made flexibly according to different application scenarios.
Have the circular groove 3 of two parallel interval on one sidewall of strip of paper used for sealing.
Have the square groove 1 of three parallel interval on another sidewall of strip of paper used for sealing and top and bottom sidewall.When square groove 1 facilitates strip of paper used for sealing and the welding of its connector, can control weld gap, prevent the unreliability of two welding between plane, improve the solderability of strip of paper used for sealing.
The hole of opening 2, strip of paper used for sealing middle part, can alleviate strip of paper used for sealing weight, and thermal capacity is little, and the design of circular groove 3 makes the strip of paper used for sealing contraction distortion little, and thermal stress is even, and due to the effect of square groove 1, makes the good welding performance of itself and peripheral connector, good product quality.
Above description is explanation of the invention, is not that limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification to the restriction of invention.
