The segment of warmware is arranged with high-temperature resistance plastice part 7, has ensured the creepage distance between terminal 2 and metal heat sink 4, and guarantee will not
Short circuit.
In the present embodiment, as shown in figure 3, metal heat sink 4 includes the inner base frame 41 and outer cover for seat 42 for being metal material,
Outer cover for seat 42 is sheathed on inner base frame 41, and mounting hole is arranged on inner base frame 41.It is the benefit that metal heat sink 4 is divided into two,
In processing, simultaneous processing molding inner base frame 41 can be distinguished and outer cover for seat 42, inner base frame 41, sleeve 3 and terminal 2 are first assembled into
One module, then this module and outer cover for seat 42 assemble, high production efficiency.As shown in Fig. 2, metal heat sink in practice
4 can be integral structure, more compact structure.As shown in figure 3, the periphery of inner base frame 41 is provided with the groove 411 of bar shaped, outside
Towards projecting inward, protrusion is partially submerged into groove 411 to limit in circumferential mutually clamping the threaded hole 422 of cover for seat 42.Pass through again
The socket 5 of the fixed outer cover for seat 42 of bolt, gun body 1 and front.The peripheral side of metal heat sink 4 is arranged with heat release hole
Heat-insulated garment bag or rubber sleeve (not shown), prevents user from being scalded by the metal heat sink 4 of high temperature.Outer cover for seat 42
Side be placed with multiple radiating fins 421, heat dissipation wind channel is formed between two neighboring radiating fin 421, metal heat sink 4
Peripheral part protrudes outwardly with respect to gun body 1, i.e. the diameter of 2 fixing piece of terminal is bigger than the diameter of gun body 1, in cover for seat 42 outer in this way
Heat dissipation wind channel two-port be connected to atmosphere, facilitate inflatable body to generate cross-ventilation in heat dissipation wind channel and take away heat.In figure
The protrusion of radiating fin 421 is only shown, metal heat sink 4 can be protruded outwardly in practice more so that the two of metal heat sink 4
The part of end face is exposed.
In practice, the length direction arrangement along terminal 2 that the arranged direction of radiating fin 421 can be as shown in the figure.In addition,
Radiating fin 421 can also be arranged along the radial direction of terminal 2, be arranged if it is around radial direction, then to be opened up in garment bag
Air inlet and air outlet.Or screw arrangement is covered around heat dissipation metal, screw arrangement can extend heat dissipation wind channel, allow wind to absorb more
Heat then flow into atmosphere, heat dissipation area is bigger.
In the present embodiment, the side of metal heat sink 4, which is provided with, can generate cross-ventilated inflatable body.Actually make
In, the heat that terminal 2 generates after being powered can be transmitted in metal heat sink 4, and constantly be spread outward.In the work of inflatable body
Under, the heat for accelerating metal heat sink 4 is dispersed into atmosphere, and the heat that terminal 2 generates also can correspondingly be accelerated toward metal
Radiating piece 4 transmits, and heat dissipation effect is greatly improved, and can satisfy higher charging gun cooling requirements.
