Drawings
The invention and its features, aspects and advantages will become more apparent from a reading of the following detailed description of non-limiting embodiments with reference to the attached drawings. Like reference symbols in the various drawings indicate like elements. The drawings are not intended to be drawn to scale, emphasis instead being placed upon illustrating the principles of the invention.
Fig. 1 is a schematic structural diagram of a seal of a connection-tight type according to embodiment 1 of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which should not be construed as limiting the invention.
Example 1:
the connecting tight seal provided by the embodiment 1 of the present invention is understood with reference to fig. 1, and includes a seal body 1; the seal body 1 comprises an upper connecting part 11 for connecting an upper clapboard, a lower connecting part 12 for connecting a lower clapboard and a supporting part 13; the upper connecting portion 11, the supporting portion 13, and the lower connecting portion 12 are connected in order in the vertical direction; the seal body 1 is strip-shaped; the top surface of the upper connecting part 11 is sequentially provided with a left wave section, a straight plate section and a right wave section; the left wave section and the right wave section comprise a wave crest section and a wave trough section; the left wave section and the right wave section are both arranged in a staggered mode through the wave crest section and the wave trough section; the lower connecting portion 12 and the upper connecting portion 11 are arranged in a central symmetry manner.
The embodiment 1 of the utility model provides a connect tight type strip of paper used for sealing when implementing, with correspond left wave section on the baffle that connecting portion 11 is connected, straight board section and right wave section are provided with the equal same depressed part or the bellying of corresponding shape size, and also correspond the left wave section of lower connecting portion 12 on the baffle that lower connecting portion 12 is connected, straight board section and right wave section are provided with the equal same depressed part or the bellying of corresponding shape size, therefore, greatly increased the welding area of strip of paper used for sealing body 1 and baffle, improve baffle and strip of paper used for sealing body 1's welding strength, improve the baffle and strip of paper used for sealing body 1's welding face the ability of enduring of high-speed fluid long-term impact, prolong plate fin heat exchanger's life. In addition, strip of paper used for sealing body 1 is central symmetry structure, the processing production of being convenient for, and stable in structure can guarantee the bearing capacity of heat exchanger body.
