In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, integrally connected, or detachably connected; may be communication within two elements; they may be directly connected or indirectly connected through an intermediate, and those skilled in the art will understand the specific meaning of the above terms in the present invention in specific situations.

As shown in fig. 1-4, a plasma cutting machine exhaust heat abstractor, including air pump 1, the gas outlet department of air pump 1 is provided with the heat dissipation part, the heat dissipation part includes cooling tube 2, cooling tube 2 is the tubular structure, and it adopts the aluminum alloy to make, and its lateral wall is provided with a plurality of heat dissipation fins 6 along its circumference interval outward, heat dissipation fin 6 is the sheet structure, and its surface is wavy, the both ends of cooling tube 2 respectively one-to-one ground with the gas outlet of air pump 1, the entry intercommunication of relief pressure valve.

The working principle of the utility model is as follows: air pump 1 exhaust high temperature compressed air gets into in the cooling tube 2, compressed air's heat transfer extremely cooling tube 2, through cooling tube 2 dispels the heat to the space around, realizes reducing the purpose of compressed air temperature, and heat dissipation fin 6 on cooling tube 2 has increased the area of contact of cooling tube 2 and air, and then has increased cooling efficiency. Also, the wavy surface of the radiating fin 6 further increases the contact area of the radiating pipe 2 with air than the straight surface. Compare in prior art's common adoption copper pipe heat dissipation, cooling tube 2 adopts the aluminum alloy material to make, has reduced manufacturing cost when having guaranteed the radiating effect, has again, and cooling tube 2 that metal copper made leads to its processing difficulty because the texture is softer, the structure that has good radiating effect among the inconvenient processing costing device, and in addition, the density of aluminum alloy is less than metal copper's density for 2 qualities of cooling tube that adopt the aluminum alloy to make are lighter, have increased joint strength when cooling tube 2 is fixed in on the plasma cutting machine has reduced plasma cutting machine's whole weight.
