Description
Technical field:
The utility model relates to a kind of blower, particularly a kind of blower cools structure.
Background technique:
Industry blower drives with motor usually.Along with the raising gradually to Fan Energy-saving and cost requirement, increasing blower selects high-speed electric expreess locomotive as drive unit.
Compared with conventional motors, high-speed electric expreess locomotive has that volume is little, power advantages of higher, but also therefore causes that high-speed electric expreess locomotive heating is high, the problem of heat radiation difficulty, and heating and heat dissipation problem along with the rotating speed of high-speed electric expreess locomotive and the raising of power remarkable all the more.And, in high-speed electric expreess locomotive because rotor surface area is little, be again moving element, its heat dissipation problem is more serious than stator.For magneto, more easily cause the risk that rotor permanent magnet high temperature demagnetizes.
The cooling of current high-speed electric expreess locomotive generally adopts air-cooled and liquid cooling two kinds of modes, but has certain narrow limitation.Air-cooled heat transfer effect is poor, for the low-power machine of below 200kW, and can only need extra cooling air blower.Liquid cooling mode can cool stator, but can not meet the cooling requirements of rotor, still needs to retain rotor cooling air, and result needs to be equipped with two cover cooling systems simultaneously.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Model utility content:
The utility model provides a kind of blower cools structure to solve above-mentioned prior art Problems existing.
The technological scheme that the utility model adopts has: a kind of blower cools structure, comprise casing, rotor, stator and spiral case, described spiral case is fixedly connected on casing, stator is located in the inner chamber of casing, rotor turns is located in stator, and the top of rotor stretches in spiral case, it also comprises cooling jacket, water cooling heat exchanger, air intake pipe and air outlet tube, described cooling jacket is arranged on casing, the epimere sidewall of casing is provided with first row pore, hypomere sidewall is provided with second row pore, and first row pore and second row pore all connect with the inner chamber of casing, the sidewall of described spiral case is provided with exhaust port, exhaust port on one end of air intake pipe and spiral case is tightly connected, the intake grill of the other end and water cooling heat exchanger is tightly connected, one end of air outlet tube and the exhaust outlet of water cooling heat exchanger are tightly connected, the other end is connected with second row port sealing.
Further, the sidewall of described casing is provided with the cooling bath installing cooling jacket.
Further, described cooling bath ringwise or spirality or snakelike.
The utility model has following beneficial effect:
(1) the utility model does not need extra cooling blower, and utilize the pressure-driven cooling air of gas in spiral case to flow, structure is simple;
(2) cold in utilizing water cooling heat exchanger to carry out the hot compressed air that spiral case is drawn, to avoid in spiral case gas temperature to the negative effect of cooling effect.
(3) can also lower the temperature by undergoes rapid expansion after the cooling air that pressure is higher enters casing, its temperature lower than room temperature, good cooling results;
(4) the utility model cooling air pressure is higher, and piping layout is easy, facilitates the direct heating component to motor to carry out emphasis cooling.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model cooling structure.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to shown in Fig. 1, the utility model blower cools structure comprises casing 1, rotor 2, stator 3, spiral case 4, cooling jacket 5, water cooling heat exchanger 6, air intake pipe 7 and air outlet tube 8, spiral case 4 is fixedly connected on casing 1, stator 3 is located in the inner chamber of casing 1, rotor 2 rotates and is arranged in stator 3, and the top of rotor 2 stretches in spiral case 4 through casing 1 sidewall.The epimere sidewall of casing 1 is provided with the first row pore 11 for discharging hot air in casing 1 inner chamber, the hypomere sidewall of casing 1 is provided with the second row pore 12 for feeding cooled gas, and first row pore 11 and second row pore 12 all connect with the inner chamber of casing 1.The sidewall of spiral case 4 is provided with exhaust port 41, and the exhaust port 41 on one end of air intake pipe 7 and spiral case 4 is tightly connected, and the other end of air intake pipe 7 and the intake grill of water cooling heat exchanger 6 are tightly connected; One end of air outlet tube 8 and the exhaust outlet of water cooling heat exchanger 6 are tightly connected, and the other end and the second row pore 12 of air outlet tube 8 are tightly connected.
The utility model is the cooling effect increasing the right casing 1 of cooling jacket 5, and the sidewall of casing 1 is provided with the cooling bath installing cooling jacket 5, and this cooling bath can ringwise or spirality or snakelike.
Gas in spiral case, normally higher than atmospheric, to part casing in cools after being cooled by the air-flow that spiral case is drawn with water cooling heat exchanger 6, omits the cooling blower of air-cooled part in blower, simplifies the cooling structure of blower.Be injected in casing 1 through the cooled cold compression air of water cooling heat exchanger 6, because casing is communicated with air, so these cold compression air can also cool by undergoes rapid expansion again, therefore the cooling air temperature introducing rotor 2 air gap can be close even lower than room temperature, flow velocity in air gap is also higher, and its cooling effect is than directly introducing air as cooled gas better effects if.
When reality uses, air intake pipe 7 directly can also be caused the heating region in blower, directly emphasis cooling be carried out to thermal source.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
