These features of the present utility model and advantage will be below embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of the cooling unit of containment in the utility model preferred embodiment;
Fig. 2 is the A place partial enlarged drawing of Fig. 1;
Fig. 3 is the B place partial enlarged drawing of Fig. 1;
Fig. 4 is the structural representation of guide plate in the utility model preferred embodiment.
[embodiment]
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the utility model embodiment's technological scheme, but following embodiment is only preferred embodiment of the present utility model, not all.Embodiment based in mode of execution, those skilled in the art are other embodiments that obtains under the prerequisite of not making creative work, all belong to protection domain of the present utility model.
With reference to Fig. 1-4, the cooling unit of containment of the present utility model, comprise cabinet 2, blower fan 1 and slip ring 4, cabinet 2 has sidepiece intake grill and top outlet inlet, blower fan 1 comprises flow blower casing 11, be positioned at the impeller of flow blower casing 11 and the motor of drives impeller, fan outlet 111 and air inlet 112 are set on flow blower casing 11, blower fan 1 is arranged on cabinet 2 tops and supports fixing by fan supporter 5, in conjunction with Fig. 3, during concrete enforcement: load onto annular fastening flange 8 in flow blower casing 11 outsides, on fastening flange 8, be provided with some spacing holes 81, fan supporter 5 is provided with mounting hole, the bottom of safety post 9 is through mounting hole, and pass through bolt, nut connects or the mode of directly welding is fixedly connected with fan supporter 5, safety post 9 upper ends are through spacing hole 81, safety post 9 is less than the aperture of spacing hole 81 through the diameter of spacing hole 81 parts, make to leave gap between safety post 9 and spacing hole 81.
Under the cooling unit normal operation of containment, the top of safety post 9 is in vacant state, can not contact with fastening flange 8, in earthquake loading situation, because the loading force being subject on three-dimensional space direction makes blower fan produce in the horizontal direction excessive vibration displacement, if the horizontal vibration displacement of blower fan surpasses the limiting distance of spacing hole 81, there is rigidity with fastening flange 8 and contact in safety post 9, restriction blower fan produces over-large displacement, avoids blower fan to topple over, and guarantees the integrity of containment unit.
In conjunction with Fig. 2, cabinet 2 tops are provided with wind outlet panel 21, sidepiece is provided with sidepiece air intake plate, above-mentioned top outlet inlet is located in wind outlet panel 21, sidepiece intake grill is located on sidepiece air intake plate and by surface cooler 3 and covers, slip ring 4 integral body are horn-like, there is choke 41 and expansion mouth 42, between air inlet 112 and wind outlet panel 21, by type metal expansion joint 6, be connected, type metal expansion joint is to be arranged on a kind of flexible structure on container shell or pipeline for compensation because of the additional stress that temperature difference and mechanical vibration cause, elastic compensating element as a kind of energy free-extension, application in the present embodiment, can move the displacement producing by air blower of compensating, simultaneously because type metal expansion joint is rigidity, can effectively prevent negative suction.
The choke 41 of slip ring 4 is connected to wind outlet panel 21 inner sides, and by being welded to connect, screw connects, bolt connects or the mode such as riveting is fixed, choke 41 is over against air inlet 112.The expansion mouth 42 of slip ring 4 extends to cabinet 2 inner spaces, makes slip ring 4 integral body all be positioned at cabinet 2 inner spaces.
Because slip ring 4 integral body of the present embodiment are all positioned at cabinet 2 inner spaces, make the Distance Shortened on slip ring 4 and cabinet 2 borders, sidepiece intake grill bottom side, thereby improved the gradient disparities of air intake wind speed in cabinet air intake surface short transverse, improved the unit air intake section uniformity; Because slip ring is transferred to cabinet inner side from cabinet outside, reduce the boundary dimension of unit integral body simultaneously, saved installing space, improved space availability ratio.
In conjunction with Fig. 4, in the present embodiment, in order better to guide the distinguished and admirable slip ring 4 that enters, on slip ring 4, guide plate has been installed, this guide plate inner side 71 is circular, and guide plate outside 72 is Octagon, and guide plate inner side 71 is connected to expansion mouth 42 edges of slip ring 4, guide plate outside 72 connects the sidepiece air intake plate top of cabinet 2, forms the water conservancy diversion conical surface 70 between the inner side of guide plate and outside.The water conservancy diversion conical surface 70 forms angle α with horizontal plane (cabinet air intake direction), and angle α≤45 °, can avoid the generation at air intake dead angle like this, thereby guarantees the whole uniformity of cabinet 2 air intake sections, further improves set heat exchange efficiency.
In other embodiments, slip ring can only partly be positioned at cabinet inside space, for example: the choke of slip ring is positioned at cabinet outside, and the expansion mouth of slip ring extends in cabinet, compared to existing technology, can reach equally the object of optimizing unit internal gas flow tissue.
The utility model embodiment is mainly used in nuclear power air-conditioning system, or similar environment.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this, is familiar with this those skilled in the art and should be understood that the utility model includes but not limited to accompanying drawing and the content of describing in embodiment above.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
