Liquid is mobile in a manner of approximate laminar flow in aluminum pipe or copper pipe, and in the utility model, coolant liquid is moved in heat-dissipating pipe inside spin,
The movement of coolant liquid is more violent, thus takes away the more heats of welding gun in the same time, welding gun cooling efficiency is promoted, in phase
It is additionally provided with strip bulge on heat dissipation inside pipe wall between adjacent two strip grooves, strip bulge is parallel with heat-dissipating pipe axis, therefore dissipates
When inside heat pipe divides the coolant liquid of screw by strip bulge, the direction of motion changes, and makes the coolant liquid in heat-dissipating pipe be in
Turbulent movement, further improves the severe degree and irregular degree of cooling liquid movement, further promotes coolant liquid and weldering
The heat exchanger effectiveness of rifle, and strip groove and strip bulge are capable of increasing coolant liquid and heat dissipation inside pipe wall contact area, improve
Coolant liquid and heat-dissipating pipe heat exchanger effectiveness, in conjunction with the radiator outer surface of high efficiency and heat radiation, the utility model heat spreader structures are compared
For existing welding gun radiator, radiating efficiency is greatly promoted, since with excellent heat dissipation performance, heat-dissipating pipe is using low in cost
Aluminium material still there is excellent radiating efficiency, therefore heat dissipation cost can also be reduced simultaneously improving radiating efficiency.
The bar shaped tooth is parallel with heat-dissipating pipe axis, and bar shaped tooth height is the 1/15-1/10 of heat dissipation pipe outside diameter.
Bar shaped tooth height is the 1/15-1/10 of heat dissipation pipe outside diameter, thus compares existing circular tube structure, the utility model heat dissipation
The heat dissipation area of tube outer surface can increase 30%-60%, and radiating efficiency is able to ascend 20%-50%, effectively improve welding gun
Cooling efficiency.
Preferably, the strip groove section is semicircle, and the depth of strip groove is the 1/ of heat-dissipating pipe sidewall thickness
2。
On the size basis of existing low-power welding gun radiator, the depth of strip groove is set as heat-dissipating pipe sidewall thickness
1/2, internal coolant screw effect can be made to reach best on the basis of ensureing heat-dissipating pipe intensity.
The strip groove number is 3-6.
The height of the strip bulge is the 1/5-1/4 of heat-dissipating pipe sidewall thickness.
The heat-dissipating pipe is aluminum pipe.
The utility model compared with prior art, has the following advantages and benefits:
A kind of heat spreader structures cooling for low-power welding gun of the utility model, the bar shaped tooth of heat dissipation tube outer surface setting
It is capable of increasing heat-dissipating pipe exterior surface area, and then increasing heat radiation area, for the radiator compared to existing low-power welding gun, heat dissipation
Efficiency significantly improves, and heat dissipation inside pipe wall is equipped with the strip groove of several Spiral distributions, and the hand of spiral one of several strip grooves
Cause, therefore the coolant liquid inside heat-dissipating pipe can be moved forward around heat-dissipating pipe axis spiral, existing welding gun cool down radiator its
Structure is usually single aluminum pipe or copper pipe, and coolant liquid is mobile in a manner of approximate laminar flow in aluminum pipe or copper pipe, and this is practical
In novel, coolant liquid is moved in heat-dissipating pipe inside spin, and the movement of coolant liquid is more violent, thus takes away welding gun in the same time
More heats promote welding gun cooling efficiency, are additionally provided with strip bulge on the heat dissipation inside pipe wall between two neighboring strip groove,
Strip bulge is parallel with heat-dissipating pipe axis, thus the coolant liquid of heat-dissipating pipe inner part screw pass through strip bulge when, movement
Direction changes, and moves coolant liquid in turbulent, further improve cooling liquid movement severe degree and
Irregular degree further promotes the heat exchanger effectiveness of coolant liquid and welding gun, and strip groove and strip bulge are capable of increasing
Coolant liquid and heat dissipation inside pipe wall contact area, improve coolant liquid and heat-dissipating pipe heat exchanger effectiveness, in conjunction with the radiator of high efficiency and heat radiation
Outer surface, for the utility model heat spreader structures compare existing welding gun radiator, radiating efficiency is greatly promoted, due to excellent
Different heat dissipation performance, heat-dissipating pipe still has excellent radiating efficiency using low-cost aluminium material, therefore radiates improving
Efficiency can also reduce heat dissipation cost simultaneously.
