Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Example 1
Referring to fig. 1 and 2, the present invention provides the following technical solutions: the utility model provides a piston of high heat dissipation type, piston body 1, piston pin 6 and piston ring 8, piston body 1 can be divided into top 3, head 2 and skirt section 4 and be the three, piston body 1 has seted up pinhole 5, piston pin 6 installs in pinhole 5, a plurality of annular 7 have been seted up to 2 departments of the head of piston body 1, be equipped with piston ring 8 in the annular 7, first heat dam 9 and second heat dam 10 have been seted up to 2 departments of the head of piston body 1, first heat dam 9 is located annular 7 top, second heat dam 10 is located annular 7 below, through the effect through first heat dam 9 and second heat dam 10, the top temperature of piston body 1 of being convenient for transmits between first heat dam 9 and the second heat dam 10, improves radiating effect.
Specifically, a plurality of grooves 11 are formed in the top 3 of the piston body 1, so that the contact area between the top 3 of the piston body 1 and the air in the cavity can be increased, and the transmission of the temperature in the cavity is accelerated.
Specifically, the zinc coating 12 is arranged at the skirt portion 4 of the piston body 1, so that not only can the situation that the cylinder is pulled due to poor lubrication of the piston be prevented, but also the abrasion of the skirt portion 4 of the piston body 1 can be reduced.
Specifically, the groove depth of the second heat insulation groove 10 is greater than that of the first heat insulation groove 9, so that heat transfer is concentrated between the first heat insulation groove 9 and the second heat insulation groove 10, and the cooling effect is improved conveniently.
Specifically, the cross sections of the first heat insulation groove 9 and the second heat insulation groove 10 are concave heat insulation grooves, which can improve the heat insulation effect of the first heat insulation groove 9 and the second heat insulation groove 10.
The working principle is as follows: after using this piston, after the combustion chamber produced a large amount of heats, the heat in the combustion chamber can be absorbed to top 3 of piston body 1 for the heat begins the downward transmission, collide first heat dam 9 back when the heat downward transmission, can be with more heat transfer to different piston rings 8 in, accelerate radiating speed, collide second heat dam 10 back when the heat downward transmission, can make a large amount of heats pile up between first heat dam 9 and second heat dam 10, the heat dissipation of each piston ring 8 of being convenient for.
