Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
It please refers to Fig.1 to Fig.3, a kind of water jacket thermal insulator 10 is placed between bearing block 1 and heating furnace 2, for bearing block 1
Cooling, specifically, including cabinet 100, input duct 200 and liquid outlet pipe 300.
Input duct 200 is set to the side wall of cabinet 100 and the bottom close to cabinet 100, and communicates with cabinet 100.Into
Liquid pipe road 200 is used to inject coolant liquid to cabinet 100.Coolant liquid can be the water or other liquid after cooled.Out
There are two liquid pipe roads 300.Two liquid outlet pipes 300 are oppositely arranged on the upper of cabinet 100, and the side opposite with input duct 200
Top on wall and close to cabinet 100.Liquid outlet pipe 300 is communicated with 200 cabinet 100 of input duct, for will be in cabinet 100
Liquid is taken away.Input duct 200 is disposed in proximity to the bottom of cabinet 100, and 200 pipeline of input duct is disposed in proximity to cabinet 100
Top, the time of circulation of the coolant liquid in cabinet 100 is conducive to extend, to improve cooling effect.
The runner passed through for coolant liquid is provided in cabinet 100.Runner is divided into entrance 110, the first interlude 120,
Two interludes 130, the first outlet flow section 140 and the second outlet flow section 150.Entrance 110, which has, is divided into horizontal segment 111 and vertical section 112.
Horizontal segment 111 is connected to after extending to the middle part of cabinet 100 along bottom from input duct 200 with vertical section 112.Vertical section
112 extend straight up, and behind the top close to cabinet 100, two sides are shunted to the left and right, are respectively formed 120 He of the first interlude
Second interlude 130.First interlude 120 finally terminates in horizontal segment 111 after sinuous.Second interlude 130 passes through
After sinuous, 100 bottom of cabinet is finally terminated in.First outlet flow section 140 is connected to the first interlude 120, and along cabinet 100
Side wall extend to the top of cabinet 100, be finally connected to liquid outlet pipe 300.Second outlet flow section 150 and the second interlude 130
Connection, the top of cabinet is extended to along the side wall of cabinet 100, is finally connected to liquid outlet pipe 300.
In use, coolant liquid enters the horizontal segment 111 of entrance 110 by input duct 200, then vertical
Two sides separately flow into the first interlude 120 and the second interlude 130 to the left and right for the tail portion of section 112.Because of 120 He of the first interlude
Second interlude 130 is detour arrangement, can extend currency of the coolant liquid in runner, can be fully cooled the cooling of liquid
Effect to reduce the dosage of coolant liquid, and then reduces energy consumption.Simultaneously as runner is detour arrangement, it is balanced on the whole
The surface temperature of entire cabinet 100.To can surface temperature to water tank it is balanced and to bearing block 1 it is balanced cooling, in turn
Cabinet 100 and bearing block 1 can be prevented because surface temperature equilibrium damages.
In one embodiment, entrance 110 is divided along flow direction is divided into three discharge orifices.First outlet flow section, 140 edge
Flow direction be divided to and be divided into two discharge orifices.Second outlet flow section 150 is divided to along flow direction is divided into two discharge orifices.And
And the cross section of each discharge orifice is identical, meanwhile, the wall thickness between interior each discharge orifice of entrance 110 is less than the partition of other discharge orifices
It is thick.Runner is divided into the wall thickness in discharge orifice and entrance 110 between discharge orifice less than wall thickness between other discharge orifices, is conducive to cool down
Liquid enters the quick diffusion after runner, plays the role of lower coolant temperature at balanced input duct 200.
In the present embodiment, the cross section of input duct 200 is greater than the sum of the cross section of two liquid outlet pipes 300.Make
Coolant liquid pressure difference, temperature between entire 100 inside of cabinet and liquid outlet pipe 300 is more stable.And allow cooling by heat exchange
Liquid has comparable pressure when reaching liquid outlet pipe 300, and then accelerates the rate of outflow of coolant liquid, and then reduces steam in runner
The interior possibility for forming steam.
Above-mentioned water jacket thermal insulator 10, is set between bearing block 1 and heating furnace 2, avoids heat and directly connects with bearing block 1
Touching prevents bearing block 1 because temperature distortion even ruptures, and then extend bearing to guarantee that bearing block 1 operates in low temperature environment
1 service life of seat.Meanwhile coolant liquid enters cabinet 100, the then runner Jing Guo detour, finally from out by input duct 200
It flows out in liquid pipe road 300.Also, runner is for multiple discharge orifices, while the wall thickness between each discharge orifice in entrance 110 is less than
Wall thickness between other discharge orifices is conducive to coolant liquid and enters quick diffusion after runner, plays lower at balanced input duct 200
Coolant temperature effect.Meanwhile the cross section of input duct 200 is greater than the sum of the cross section of two liquid outlet pipes 300, from
And make the rate of outflow that can accelerate coolant liquid, and then reduce the possibility that steam forms steam in runner.
Finally, it should be noted that the basic principles and main features that the utility model has been shown and described above are practical with this
Novel advantage, it is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments,
And without departing substantially from the spirit or essential attributes of the utility model, it can realize in other specific forms practical
It is novel.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical
Novel range is indicated by the appended claims rather than the foregoing description, it is intended that the equivalent requirements of the claims will be fallen in
All changes in meaning and scope are embraced therein.It should not treat any reference in the claims as limiting
Claim involved in making.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
