Specific implementation mode
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The utility model embodiment includes：
A kind of plate heat exchanger high intensity fastening nut, including：Inner ring 3, threaded hole 4, link 5, outer shroud 1 and compound
Layer 2,3 centre of the inner ring are equipped with threaded hole 4, and the inner ring 3 is connected with outer shroud 1 by link 5, the table of the outer shroud 1
Face is equipped with composite layer 2, this nut is intermediate engraved structure, is connected using link between inner ring and outer rings, under high temperature environment,
Nut heat dissipation effect more, the assembly intensity of plate heat exchanger also higher.
In addition, the inner ring 3, threaded hole 4, link 5, outer shroud 1 are made of cast iron, hardness is high, and intensity is high, heat-resisting quantity
By force, the inner ring 3, threaded hole 4, link 5,1 surface of outer shroud are sprayed with protective paint, further increase the service life of nut.
In addition, the threaded hole 4 contains stratum granulosum, stratum granulosum is carbon particle layer, and intensity is high, and wear-resistant coefficient is high, assembly
When, the connection of nuts and bolt is more secured, and intensity is high.
The utility model plate heat exchanger is with the advantageous effect of high intensity fastening nut：
It is simple in structure, it using the duplex of inner ring outer shroud, is designed to hollow type nut, enhances heat dissipation effect, screw thread
Layer inner wall is equipped with grain structure, also increases assembly intensity, improves construction efficiency.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is equally included in the patent within the scope of the utility model.
