Device radiates, and the hot water cooling after heat dissipation becomes is recycled inside cold water inflow water tank, saves the use cost at water source,
The first supporting block and third through-hole in the second supporting block and fourth hole separate water inlet pipe and outlet pipe simultaneously, so that into
Water pipe is isolated with the hot water or cold water inside outlet pipe, reduces temperature reciprocal effect, it is internal that seal plug blocks top
Water flow prevents water flow from entering to inside mandril.
Preferably, first through hole and the second through-hole, the water inlet pipe and outlet pipe are had above the seal plug
It extends through in first through hole and the second through-hole.
First through hole and the second through-hole on this setting seal plug are used for across water inlet pipe and outlet pipe.
Preferably, first supporting block is identical with the second support block structure, first supporting block and the second supporting block
On be provided with third through-hole and fourth hole, the water inlet pipe and outlet pipe are extended through in third through-hole and fourth hole.
This first supporting block of setting and third through-hole in the second supporting block and fourth hole are water inlet pipe and outlet pipe
It separates, so that water inlet pipe is isolated with the hot water or cold water inside outlet pipe, reduces temperature reciprocal effect.
Preferably, the water inlet pipe and outlet pipe are stereoplasm tube.
This setting water inlet pipe and outlet pipe are that stereoplasm tube is to avoid water inlet pipe from contacting with outlet pipe to generate temperature difference influence.
Preferably, filler is equipped with above the water tank.
This setting filler for adding clear water to water tank inside in time.
Preferably, first connecting tube and the second connecting tube are flexible pipe.
This first connecting tube of setting and the second connecting tube are the operation and installation that flexible pipe is easy for device entirety.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, the present invention provides a kind of technical solution: a kind of piercing mandrel plug cooling device, including mandril are small
Vehicle 1, mandril 2 and top 3, the mandril 2 are installed between mandril trolley 1 and top 3, are respectively sleeved on inside the mandril 2
Water inlet pipe 4 and outlet pipe 5, described 2 inside one end of mandril are equipped with seal plug 6, the water inlet pipe 4 and 5 one end of outlet pipe point
It is not connected with the first connecting tube 7 and the second connecting tube 8, first connecting tube 7 and 8 one end of the second connecting tube are respectively communicated in water
Case 9 is equipped with water circulating pump 10 in first connecting tube 7, radiator 11, the top is equipped in second connecting tube 8
