Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a heat exchanger for cooling a nacelle of a wind turbine generator set. Background Art

[0002] Wind turbine nacelle cooling refers to a series of measures and technologies taken to keep the internal components of the wind turbine within a suitable operating temperature range. Since wind turbines generate heat during operation, especially components such as gearboxes, generators and inverters, if they are not effectively cooled, it may cause the equipment to overheat, affecting its performance and life. During the normal cooling process, the wind turbine nacelle cooling heat exchanger is a device specially used for internal thermal management of wind turbines. Its function is to transfer the heat generated inside the nacelle to the external environment to keep the internal components of the nacelle within a suitable operating temperature range. The application of heat exchangers in wind turbines is mainly to cool key components.

[0003] The plate radiator consists of a series of parallel metal plates, with tight fluid channels formed between these metal plates. Usually, two fluids of different temperatures flow through these channels: one is the hot fluid and the other is the cold fluid. When the hot fluid flows through the channel, the heat is transferred to the metal plate by convection, and then through the heat conduction of the metal plate, the heat is transferred from the metal plate to the cold fluid on the other side, thereby achieving heat exchange.

[0004] However, in actual use, since the working principle of the heat exchanger is based on heat transfer between two fluids, the ambient temperature directly affects the initial temperature of the fluid, thereby affecting the temperature difference and efficiency of the heat exchange. When the temperature is low, ice will form a layer of ice on the surface of the heat exchanger. This layer of ice will hinder heat transfer and cause a significant decrease in heat exchange efficiency. Once the ice layer is formed, it will reduce the cross-sectional area of ​​the fluid channel and increase the resistance to fluid flow, thereby increasing pressure loss. Excessively high external temperature may cause changes in the physical properties of the fluid, such as viscosity and thermal conductivity. These changes may affect the heat exchange efficiency. Summary of the invention

[0005] The present invention proposes a heat exchanger for cooling the cabin of a wind turbine generator set, which solves the existing problem in the related art that in extreme weather, the temperature is too low and ice forms a layer of ice on the surface of the heat exchanger, which hinders heat transfer and causes a significant decrease in heat exchange efficiency. Once the ice layer is formed, the cross-sectional area of ​​the fluid channel is reduced, and the resistance to fluid flow is increased, thereby causing an increase in pressure loss. Excessively high external temperature may cause changes in the physical properties of the fluid, such as viscosity and thermal conductivity, and these changes may affect the heat exchange efficiency.

[0045] Specifically, the moving motor 602 is started to drive the reciprocating screw rod 603 to rotate, so that the driving block 604 is driven to move up and down reciprocatingly, thereby moving the air guide frame 701 and cooling or heating the channel plate group 3.

[0046] Furthermore, the sealing assembly 709 includes two extension plates 7091 fixedly connected to one side of the air guide frame 701, a micro electric cylinder 7092 fixedly connected to a side close to the two extension plates 7091, a sealing plate 7093 fixedly connected to the output end of the micro electric cylinder 7092, and the sealing plate 7093 cooperates with the drive port 702 and multiple fan guide fans 707.

[0047] Specifically, when in use, the sealing plate 7093 is pushed to fit the driving port 702 and the plurality of fan guides 707 through the micro electric cylinder 7092 , so that the redundant portion of the driving port 702 can be sealed, thereby protecting the Peltier cooler 706 .

[0049] Specifically, the worm gear 9043 is driven to rotate by rotating the worm gear 9044, and then the worm gear 9043 drives the threaded rod 9042 to rotate, pushing the reinforcement rod 903 and the moving block 902 to move. When moving to a certain position, the worm gear 9044 can lock the worm gear 9043, which can reduce the impact of vibration, achieve two-layer fixation, and improve its stability after installation.

[0050] Furthermore, the external component 10 includes an external flange 101 installed on one side of the frame plate 1, a detection port 102 opened on the upper side of the external flange 101, a flow detector 103 welded to the inner wall of the detection port 102, and a blocking net 104 fixedly connected to the inner wall of the external flange 101.

[0051] Specifically, the external flange 101 has high detachability, which improves the convenience of maintenance. The flow pressure during use can be detected in the detection port 102 through the flow detector 103. If there is an internal leak inside the heat exchanger, it may cause a change in the fluid flow path, thereby causing an abnormal pressure drop. This abnormal pressure drop may be a sign of an internal leak, which is convenient for personnel to observe and distinguish the internal leak. The blocking net 104 can filter the flowing liquid, and the blocking net 104 can be removed for cleaning, which improves the convenience of subsequent cleaning.

[0052] Furthermore, a temperature control component 11 is provided on one side of the frame plate 1;

[0053] The temperature control assembly 11 includes a control box 111 fixedly connected to one side of the frame plate 1, and a temperature sensor 112 fixedly connected to the upper side of the control box 111. The control box 111, the micro waterproof motor 703, the Peltier cooler 706, the fan 707, and the micro electric cylinder 7092 are electrically connected.

[0054] Specifically, the control box 111 is connected to an external power supply, and the normal air is monitored through the temperature sensor 112. When the temperature is too high or too low, the internal electrical components can be controlled by the control box 111 to cool down or heat up the temperature, thereby improving the degree of automation. The temperature sensor 112 is a common device on the market. The control box 111 is set with a certain program and is electrically connected to the moving motor 602.

[0055] Furthermore, a maintenance groove 12 is provided at the lower side of one of the two extension plates 7091 , an L-shaped plate 13 is slidably fitted on the inner wall of the maintenance groove 12 , and a brush 14 is provided on the lower side of the inner wall of the L-shaped plate 13 .

[0056] Specifically, by holding the L-shaped plate 13 and moving it in the maintenance slot 12 , the brush 14 cleans the dustproof net 708 , thereby increasing the convenience of subsequent maintenance of the dustproof net 708 .

[0057] Furthermore, a support plate 15 is fixedly connected to one side of the two guide rods 2 , support legs 16 are fixedly connected to the lower sides of the frame plate 1 and the support plate 15 , and dispersion pads 17 are fixedly connected to the lower sides of the plurality of support legs 16 .

[0058] Specifically, by inserting corresponding fasteners into the support feet 16 and by placing the dispersion gasket 17 between the support feet 16 and the installation position, it can help to place the items stably, distribute the weight, and prevent damage caused by excessive local pressure.

[0059] The implementation principle of the glass curtain wall vibration monitoring instrument control device of the embodiment of the present application is as follows: when in use, it can first be connected and fixed to the ground through the corresponding support feet 16, and can be realized through the dispersion gasket 17. If the surface of the installation position is uneven or has bumps, it can help to place the items stably, disperse the weight, and prevent damage caused by excessive local pressure. Then, multiple channel plate groups 3 are assembled, and corresponding sealing gaskets are provided between the multiple channel plate groups 3;

[0060] Then, the tightening rod 502 is inserted into the communication port 501, and the fixing nut 503 is tightened to tighten the clamping plate 4 and the frame plate 1, so that the channel plate group 3 is squeezed to achieve sealing therebetween, and the anti-skid pad 504 can reduce the possibility of the fixing nut 503 loosening. By rotating the worm 9044, the threaded rod 9042 and the worm wheel 9043 are driven to rotate, and the moving block 902 is pushed to move. Then, the reinforcing rod 903 is inserted into the reinforcing groove 8 to fix the clamping plate 4 and the guide rod 2, and two-layer fixation is achieved. The locking principle between the worm 9044 and the worm wheel 9043 can reduce the influence of loosening due to vibration, so that if the fixing nut 503 is accidentally loosened, a backup fixation can be performed to avoid the situation of large-area leakage caused by bolt loosening, thereby improving the overall stability and safety. The reinforcing groove 8 can be set in a trumpet shape, and the reinforcing rod 903 will be gradually tightened with it after insertion;

[0061] After the fixing is completed, the external flange 101 in the external component 10 is connected to the external cooling pipe, and it has high detachability. The flow pressure during use can be detected in the detection port 102 through the flow detector 103. If there is an internal leakage inside the heat exchanger, it may cause a change in the fluid flow path, thereby causing an abnormal pressure drop. This abnormal pressure drop may be a sign of internal leakage, which is convenient for personnel to observe and distinguish internal leakage. The blocking net 104 can filter the flowing liquid, and the blocking net 104 can be cleaned by removing the blocking net 104, which improves the convenience of subsequent cleaning;

[0062] In daily use, the control box 111 is connected to an external power supply, and the normal air is monitored through the temperature sensor 112. When the temperature is too high or too low, the signal is transmitted to the control box 111, and the moving motor 602 can be controlled to rotate the reciprocating screw 603, so that the driving block 604 moves up and down in the driving slot 601. While moving, the corresponding guide fan 707 and Peltier cooler 706 are started. The Peltier cooler 706 is an electronic component based on semiconductor materials that can simultaneously realize the two functions of cooling and heating and can be used for precise temperature control. When the temperature is high, the cooling surface and the corresponding guide fan 707 can face the channel plate group 3, and the sealing plate 7093 can be pushed by the micro electric cylinder 7092 to seal the driving port 702 to remove the excess position of the Peltier cooler 706, so as to achieve heat insulation on both sides of the installation port 705, so as to achieve the cooling wind blown out by the air guide frame 701, which is used to circulate and blow the channel plate group 3 for cooling;

[0063] When the temperature is low, the sealing plate 7093 is first contracted by contracting the micro electric cylinder 7092 to release the limit on the linkage plate 704, and then the linkage plate 704 is turned 180 degrees by starting the micro waterproof motor 703 to turn the heating and cooling surfaces, and then the sealing plate 7093 is reset to separate the hot and cold points, thereby changing the wind blown out of the air guide frame 701 to hot air. In a cold environment, blowing hot air can prevent ice from forming on the surface of the heat exchanger and protect the equipment from freezing damage. At the same time, blowing hot air can increase the surface temperature and reduce the possibility of condensation, thereby avoiding corrosion and degradation of insulation performance caused by condensation.

[0064] During the movement, the cleaning brush plate 18 will follow the movement to clean both sides of the channel plate group 3, and then separate the adsorbed dust by blowing air, which can remove dirt, sediment and debris on both sides of the heat exchanger to a certain extent. These substances will hinder the transfer of heat and reduce the heat exchange efficiency. After cleaning, the heat exchange performance of the heat exchanger can be restored or improved.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
