Position；Water channel is equipped in engine base, has coolant to circulate in water channel；Closedown structure is additionally provided on engine base, closedown structure will be cold
But the circulation of liquid is limited in water channel, prevents coolant from leaking outside.
Wherein, double-barrel structure is the engine base outer barrel and engine base inner cylinder that can paste circular heat source, and engine base outer barrel is socketed in engine base
The outside of cylinder, the thickness of engine base outer barrel are more than the thickness of engine base inner cylinder.
Also, water channel is accompanied between engine base outer barrel and engine base inner cylinder, water channel direction is perpendicular to engine base outer barrel and engine base inner cylinder
Extending direction, water channel is helically wound around the outside of engine base inner cylinder and the inside of engine base outer barrel.
Also, water channel is to process to obtain or in the processing acquisition of the outside of engine base inner cylinder or simultaneously in the inside of engine base outer barrel
It processes and obtains in the inside of engine base outer barrel and the outside of engine base inner cylinder.
Meanwhile engine base outer barrel is equipped with water inlet tap and faucet with engine base inner cylinder, water inlet tap is connected to water with faucet
Road；It cools down medium and water channel is flowed by water inlet tap, and water channel is flowed out from faucet.
In addition, being provided with base mounting structure on the outside of engine base outer barrel, the outside of base mounting structure is cold by bitubular liquid
But device with extraneous mutually fixed, with heat source mutually fix by the inside of base mounting structure.
In addition, closedown structure includes weld seam；Weld seam is formed when being processed welding with engine base inner cylinder to engine base outer barrel
Bound fraction, weld seam are arranged at the binding site of engine base outer barrel and engine base inner cylinder, and water channel locking is the interior environment of connection by weld seam.
Also, closedown structure further includes stifled item；Weld seam and stifled item are arranged between engine base outer barrel and engine base inner cylinder, weld seam with
The outside for blocking up item is no more than the outside of engine base outer barrel and engine base inner cylinder, and the thickness of weld seam and stifled item is less than in engine base outer barrel and engine base
The depth in gap between cylinder.
Meanwhile closedown structure further includes sealing material, sealing material is that can bear seam displacement and with water seal
Fluid sealant or sealing ring, sealing material are arranged at the gap between engine base outer barrel and engine base inner cylinder, and water channel locking is by sealing material
The watertight environment of connection.
From the above it can be seen that technical solution provided by the invention have by using the engine base water channel of double-barrel structure it is cold
But liquid Xun Huan prevents the technological means of coolant leakage with closedown structure, avoids weld grinding leak, peeling paint, surface thick
It is rough, smooth engine base surface can be formed.
