Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Refer to Fig. 1-2, a kind of gas cooling device of double stage roots blower, including roots blower 1 and heat sink
2, roots blower 1 includes first order roots blower 11 and second level roots blower 12, first order roots blower 11 and second level sieve
The inner chamber of thatch blower fan 12 is provided with two groups of identical three lobe rotors 13, is crisscross arranged between two groups of three lobe rotor 13, and two
Turning to conversely, turning to for group three lobe rotor 13 can cause to quickly complete turnover into the wind in blower fan on the contrary；First order Roots
Air inlet 111 is installed, air inlet 111 absorbs from extraneous wind, is provided with out on second level roots blower 12 on blower fan 11
Air port 121, air outlet 121 will be discharged through the wind of blower fan；The centre of first order roots blower 11 and second level roots blower 12
Heat sink 2 is installed, heat sink 2 includes installing case 3, the first heat sink 4 and the second heat sink 5, first order Roots
Blower fan 11 and second level roots blower 12 are connected by intermediate connection tube 14 with case 3 is installed, and the inner chamber for installing case 3 is provided with first
The heat sink 5 of heat sink 4 and second, in the left and right sides for installing case 3 four size identical thermal vias are provided with,
The heat come out in first heat sink 4 and the second heat sink 5 can be discharged to outdoor by thermal vias；First drop
Warm device 4 includes air storage chamber 41, cooling chamber 42, gas transport pipe 43 and sealing coat 44, and the upper and lower ends of cooling chamber 42 are respectively provided with
Have in air storage chamber 41, air storage chamber 41 and gas temperature sensor 411 be installed, can at any time monitor gas temperature in the duct,
To be adjusted in time, one end of air storage chamber 41 is connected with intermediate connection tube 14, and the other end and the gas of air storage chamber 41 are transported
Defeated pipe 43 is connected, and gas transport pipe 43 is arranged in cooling chamber 42, and the inner chamber of cooling chamber 42 is provided with coolant 421, and gas
Body delivery tube 43 is multilamellar bend pipe structure, and this structure can ensure that gas transport pipe 43 fills with the coolant 421 in cooling chamber 42
Tap is touched, and is more rapidly performed by the cooling of gas, improves the efficiency of cooling；Pacify on the left and right sides wall of the inner chamber of cooling chamber 42
Equipped with cooling piece 422, when the gas temperature of conveying can't reach effect under the cooling effect of normal cooling liquid 421, still
Continue rise, and gas temperature sensor 411 detect temperature will exceed blower fan born maximum temperature when, it is possible to
Auxiliary temperature-reducing is carried out by cooling piece 422, in time by temperature control within adjustable extent, to be unlikely to cause the damage of machinery
It is bad, sealing coat 44 is provided with the right and left of cooling chamber 42, the inner chamber of sealing coat 44 is provided with heat-absorbing material, by cooling
Liquid 421 is absorbed in the case that gas temperature and cooling piece 422 freeze, and is required for discharging heat, and now heat-absorbing material is just
Temperature can be siphoned away, so as to the temperature of absorption is discharged to into interior by thermal vias, reduce the purpose of temperature；Second drop
Warm device 5 includes water tank 51 and water pipe 52, and water pipe 52 is connected with water tank 51, and water pipe 52 is interspersed to be arranged on cooling chamber 42 and isolation
In the inner chamber of layer 44, and the bottom for installing case 3 is extended to, and water pipe 52 is multilamellar bend pipe structure, can increase water pipe 52 and gas
The contact of body delivery tube 43, so as to when entering water-filling and lowering the temperature, can more rapidly, the water of water in water pipe 52 flowing also exists
In a way, improve the effect of cooling.
In sum：Gas can be accompanied by the pressurization of gas by first order Roots blower 11 so that on gas temperature
Rise, if now temperature be transferred to second level Roots blower 12 can cause because temperature is too high fan bearing hold can't stand it is too high
Temperature, easily cause machinery failure, can also reduce the efficiency of blower fan；And expellant gas temperature is also because different situations is needed
Otherwise it is same to treat, after the heat sink cooling in installation case 3, it is possible to the scope of temperature is controlled, if need not lower the temperature
Excessively, with regard to directly being lowered the temperature by coolant 421, when needing to carry out deeper cooling, then can be by increasing water pipe
Circulating water in 52 is lowered the temperature, and can also be lowered the temperature by cooling piece 422 so that whole structure can seem more preferable.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
