[0001] The present invention relates to the technical field of heat dissipation of ship equipment, in particular to a heat dissipation device for ship electrical equipment. Background Art

[0002] Ship electrical equipment includes three parts: ship power station equipment, distribution equipment and ship electric traction equipment. The ship power station equipment mainly includes the components of the ship power system, ship generators, main power stations and emergency power stations. The equipment is installed in the distribution cabinet, which contains multiple electrical components. The components will generate heat during operation. At this time, the components in the distribution cabinet need to be cooled to avoid damage.

[0003] Existing power distribution cabinets generally use natural ventilation or forced air cooling for heat dissipation, which has large heat dissipation limitations and cannot dissipate heat in different areas for heating components. Moreover, the heat dissipation effect is poor when only air cooling is used.

[0004] In view of the above problems, the present invention provides a heat dissipation device for marine electrical equipment to solve the above problems. Summary of the Invention

[0022] Sealing grooves are provided at the upper and lower ends of the sealing plate, and when the sealing plate is in a vertical state, the sealing grooves of the plurality of sealing plates are in contact with each other and sealed.

[0023] Furthermore, preferably, the conversion component includes:

[0031] Compared with the prior art, the present invention provides a heat dissipation device for marine electrical equipment, which has the following beneficial effects:

[0032] In the present invention, the heat dissipation component adopts a linear motor to drive a movable fixed frame, combined with multiple equidistant heat dissipation fans and cooling pipes with cooling holes to form dual-mode heat dissipation, improve heat dissipation efficiency, and cooperate with multi-point arranged heat sensors to adjust the heat dissipation intensity in real time for different electrical components. During heat dissipation, when the components in the distribution cabinet are initially started, multiple sealing plates are synchronously unfolded through the conversion component, thereby performing natural ventilation and heat dissipation to save energy. When the heat sensor detects that the temperature inside the distribution cabinet is overheated, multiple sealing plates are closed at this time, and only the sealing plates located above and below are kept open, and dual-mode heat dissipation is performed through the heat dissipation component, so that the cooling gas fills the distribution cabinet for overall heat dissipation. When the heat sensor detects that the temperature of a local component in the distribution cabinet is overheated, the heat dissipation component moves to the overheating position, and opens the sealing plate corresponding to its position, and enables one heat dissipation component to perform air intake operation and the other to perform air exhaust operation, thereby quickly dissipating the heat of the component and avoiding the overheated component affecting the surrounding components.

[0040] Reference Figures 1-6The present invention provides a technical solution: a heat dissipation device for ship electrical equipment, comprising:

[0041] Power distribution cabinet 1, installed on the ship;

[0042] A cover plate 2 is detachably mounted on the power distribution cabinet 1;

[0043] The heat dissipation components 3 are configured as two and symmetrically arranged on the cover plate 2;

[0044] The regulating components 4 are configured as two and symmetrically arranged on both sides of the power distribution cabinet 1;

[0045] The conversion assembly 5 is fixed on a side of the power distribution cabinet 1 away from the cover plate 2;

[0046] The heat sensors are configured in multiple numbers, arranged in the power distribution cabinet 1 , and corresponding to the electrical components in the power distribution cabinet 1 .

[0047] It should be noted that by arranging heat sensors at multiple points, one can be arranged every 0.5m², and the heat dissipation intensity can be adjusted in real time for different electrical components, thereby improving the heat dissipation efficiency of the heat dissipation component 3.

[0048] In this embodiment, the heat dissipation component 3 includes:

[0049] A linear motor 31 is fixed on a side of the cover plate 2 close to the power distribution cabinet 1;

[0050] A fixing frame 32 fixed to the output end of the linear motor 31;

[0051] The heat dissipation fans 33 are configured as a plurality and are equidistantly arranged in the fixing frame 32;

[0052] A cooling frame 34 is fixed in the fixing frame 32;

[0053] The cooling pipe 35 is fixed in the middle of the cooling frame 34 and has a plurality of cooling holes 36 on its side wall. One end of the cooling pipe 35 is connected to an external cooling device through a hose.

[0054] That is to say, the heat dissipation component 3 uses a linear motor 31 to drive the movable fixed frame 32, combined with multiple equidistant heat dissipation fans 34 and a cooling pipe 36 with cooling holes 36, to form a dual-mode heat dissipation of natural wind and cooling gas, thereby improving the heat dissipation efficiency.

[0055] As a preferred embodiment, the fixing frames 32 of the two heat dissipation components 3 are slidably arranged in the power distribution cabinet 1 at one end away from the linear motor 31 , and the two fixing frames 32 are located on both sides inside the power distribution cabinet 1 .

[0056] That is to say, arranging the fixing frames 32 on both sides of the power distribution cabinet 1 can greatly improve the air circulation efficiency inside the power distribution cabinet 1 , thereby preventing heat accumulation in the power distribution cabinet 1 .

[0057] As a preferred embodiment, the adjustment component 4 includes:

[0058] The sealing plate 41 is configured in multiple pieces and is rotatably arranged in the power distribution cabinet 1 by a rotating shaft 42;

[0059] A driving gear 43 is fixed to one end of the rotating shaft 42 close to the conversion assembly 5, and a torsion spring is provided between the other end of the rotating shaft 42 and the power distribution cabinet 1;

[0060] The sealing grooves 44 are formed at the upper and lower ends of the sealing plate 41 , and when the sealing plate 41 is in a vertical state, the sealing grooves 44 of the plurality of sealing plates 41 are in contact with each other and sealed.

[0061] When the power distribution cabinet 1 is not in use, that is, when the ship stops sailing, the multiple sealing plates 41 are sealed by torsion springs, thereby preventing dust from entering when the ship is moored.

[0062] As a preferred embodiment, the conversion component 5 includes:

[0063] A conversion chamber 51 is fixed to an end of the power distribution cabinet 1 away from the cover plate 2;

[0064] Two sliding plates 52 are symmetrically slidably disposed in the conversion chamber 51;

[0065] The driving motors are configured as two and are symmetrically fixed in the conversion chamber 51 , and the output ends are fixedly connected to the two sliding plates 52 respectively using connecting blocks 53 ;

[0066] The driving motors 54 are configured as a plurality and fixed on one side of the sliding plate 52 , and the number of the driving motors 54 is the same as that of the sealing plates 41 ;

[0067] The racks 56 are configured in a plurality, each of which is slidably disposed in the sliding plate 52 by a guide column 55 and is connected to the output end of the pushing motor 54 .

[0068] Among them, when the sealing plate 41 needs to be opened, the rack 56 corresponding to the sealing plate 41 to be opened slides by pushing the motor 54, so that the rack 56 engages with the driving gear 43, and then the driving motor drives the sliding plate 52 to slide, so that the sealing plate 41 is opened and closed.

[0069] It should be noted that multiple sealing plates 41 can be opened and closed individually, and the opening and closing angles are adjusted according to the heat distribution inside the distribution cabinet 1 to avoid overcooling of some components. When expanding, the driving gear 43 of the sealing plate 41 at a higher heat position is first engaged with the rack 56. When the sealing plate 41 is expanded to a certain angle, the driving gear 43 of the sealing plate 41 at a lower heat position is engaged with the rack 56, thereby completing the different expansion angles of multiple sealing plates 41.

[0070] As a preferred embodiment, the initial state of the rack 56 is away from the driving gear 43, and at this time the sealing plate 41 is in a vertical sealing state.

[0071] As a preferred embodiment, the opening and closing state of the sealing plate 41 is driven by the conversion component 5, and the sealing plate 41 has three opening and closing states.

[0072] When the temperature inside the power distribution cabinet 1 is low, the sealing plates 41 are in the first state, and the plurality of sealing plates 41 are all in the expanded state. At this time, the heat dissipation component 3 is in the non-working state, and heat is dissipated through natural ventilation, thereby reducing energy consumption.

[0073] When the temperature inside the power distribution cabinet 1 continues to rise, the sealing plate 41 is in the second state. At this time, the two heat dissipation components 3 are located at the top and simultaneously ventilate and dissipate heat into the power distribution cabinet 1. At this time, only the sealing plates 41 located at the top and bottom remain open, so that cooling air enters from the top and is discharged from the bottom, ensuring that the heat inside the power distribution cabinet 1 is discharged while the cooling air is used to dissipate the heat inside the power distribution cabinet 1 as a whole.

[0074] When a local component in the distribution cabinet 1 is overheated, the sealing plate 41 is in the third state. At this time, the heat dissipation component 3 is moved to the overheated component through the linear motor 31, and then the corresponding sealing plate 41 is opened, and one heat dissipation component 3 performs air intake operation and the other performs air exhaust operation, so as to quickly discharge the heat of the component and avoid the overheated component affecting the surrounding components.

[0075] Specifically, first, when the component is running, the regulating component 4 is adjusted to the first state through the conversion component 5, and natural ventilation and heat dissipation are performed. When the heat of the component increases, the regulating component 4 is adjusted to the second state through the conversion component 5, and dual-mode heat dissipation is performed through the heat dissipation component 3. When the local component is overheated, the regulating component 4 is adjusted to the third state through the conversion component 5, and the two heat dissipation components 3 are made to perform air intake and exhaust operations, so that the cooling gas passes through the component for cooling, and the heat on the component is quickly discharged to prevent the overheated component from affecting the surrounding components.

[0076] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
