Described heat exchanger comprises internal layer corrugated sheet and outer corrugated sheet, and the periphery of inside and outside layer corrugated sheet is tightly connected by rubber strip, is provided with the air inlet and the exhaust port group that are connected with air pipe line on the internal layer corrugated sheet.Described internal and external layer corrugated sheet constitutes the fluted body structure, and air inlet is arranged on the groove floor, and the exhaust port group is opened on the side all around of groove structure.The described shell of going up the cover both sides stretches out cover both sides down respectively, is the fluted body structure of both ends open.
Beneficial effect of the present invention:
1. the present invention replaces traditional fan that passes through directly air-flow inside and outside the cabin to be exchanged, and reaches the heat exchange effect, can be used for the engine room heat exchange that the inside and outside gas exchange occasion in cabin is not carried out in airtight cabin.
2. the present invention is provided with cooling unit in the cover on the cabin, and it adopts the natural wind cooling to carry out heat exchange, and the fan on it is connected with the blower fan master control system, controls start and stop and operating air velocity automatically by the blower fan master control.The low control of more traditional constituent cost is used simple.
3. the heat exchanger among the present invention is made of the sealing of inside and outside layer corrugated sheet, is connected with air pipe line on the internal layer corrugated sheet, is used for carrying out heat exchange with the external world; The side has the circulation that the exhaust port group is used for gas in the cabin around its internal layer corrugated sheet, and its inside and outside layer corrugated sheet constitutes the fluted body structure, for heat exchanger being stretched out the cover better and extraneous heat exchange in both sides under the cabin.

Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Embodiment 1: as Fig. 1-shown in Figure 4, the present invention includes going up cover 6, covering 7 and place the interior cooling units 5 of cover 6 down of being tightly connected, described cooling unit 5 comprises heat exchanger 501, air pipe line 502, fan 503, air pipe line 502 1 ends connect fan 503, the other end connects heat exchanger 501, the described cover 6 gone up is provided with the shell 510 that is used to put heat exchanger 501 that communicates with the external world along generator 4 axis both sides, heat exchanger 501 places in the shell 510, and be tightly connected with last cover 6, constitute the sealing engine room cover that heat exchanger 501 communicates with the external world.Fan 503 on it is connected with the blower fan master control system, controls start and stop and operating air velocity automatically by the blower fan master control.As shown in Figure 1, during installation, the present invention is connected with wheel hub 2, and inside is equipped with the gear-box 3 and the generator 4 of wind power generating set.
As Fig. 5, shown in Figure 6, described heat exchanger 501 comprises internal layer corrugated sheet 508 and the outer corrugated sheet 509 that heat-conducting property is good, the periphery of inside and outside layer corrugated sheet 508,509 is tightly connected by rubber strip 506, is provided with the air inlet 507 and the exhaust port group 505 that are connected with air pipe line 502 on internal layer corrugated sheet 508.
The control of fan of the present invention is to be finished by the blower fan master control system.In cabin cover body 6, be provided with temperature transducer; by temperature transducer ambient temperature in the cabin cover body 6 is passed to master control system; according to programmed values; when temperature in the cabin cover body 6 surpasses setting value; fan 503 starts; when the ambient temperature value of overstepping the extreme limit, the blower fan stopping alarm, fan 503 continues operation.When temperature when control range changes, can control fan 503 and select at a high speed or the low cruise states.
Working procedure of the present invention:
When fan operation, when gear-box 3 and generator 4 are lost to the interior heat of engine room cover above permitted value, fan 503 starts, hot air in the engine room cover is sucked air pipe line 502, be transported among the heat exchanger 501 that constitutes by two corrugated sheets, the entrained heat of swiftly flowing hot air is absorbed by heat exchanger 501, and heat exchanger 501 contacts with the cool air fluid that the outer tower tube of engine room cover is highly located wind speed, with the heat transferred external world.
The heat that gear-box 3 and generator 4 produce when blower fan low cruise of the present invention or shutdown is limited, does not need cooling usually.And the blower fan heat that gear-box 3 and generator 4 produces when power increases all will increase, when unit rated power generates electricity, the heat that produces is maximum, if wind speed continues to increase power and will no longer increase, the heat that produces also no longer increases, and the heat output of heat exchanger 501 only can improve along with the flow velocity of cool air and increase this moment.As long as the heat dissipating capacity when therefore the exchange capability of heat of heat exchanger 501 of the present invention satisfies the generating of unit rated power, the heat transfer that wheel hub 2 is highly located under the rated wind speed require.
Embodiment 2: this example is identical with embodiment's 1 overall structure, different is: described internal and external layer corrugated sheet 508,509 constitutes the fluted body structure, periphery is tightly connected by rubber strip 506, and air inlet 507 is arranged on the groove floor, and exhaust port group 505 is opened on the side all around of groove structure.As shown in Figure 3, Figure 4, for making the radiating effect in the cabin better, the fluted body structure that this routine described shell is a both ends open 511, on cover 6 both sides shell 510 stretch out cover 7 both sides down respectively.The internal and external layer corrugated sheet 508,509 of its fluted body is connected on the connecting plate 8 of cover 6 and 510 on shell, and internal layer corrugated sheet 508 constitutes the sealing engine room cover that the heat exchanger 501 and the external world communicate in engine room cover.
