In the initial stage of starting, the heat dissipation piece does not work, at the moment, heat generated by the diesel generator can rapidly increase the temperature of cooling liquid in the circulation box to the optimal working temperature, and therefore the situation that power output is delayed after the unit is started due to the fact that the temperature of the cooling liquid rises slowly in the initial stage of starting is avoided; when the temperature of the cooling liquid reaches the optimal working temperature, the heat dissipation piece maintains the temperature of the cooling liquid, and performance reduction and service life shortening of the diesel generator caused by over-high temperature of the cooling liquid are avoided.

Description

Technical Field

[0001] This utility model relates to a heat dissipation mechanism, specifically a heat dissipation mechanism for a high-voltage diesel generator set. Background Technology

[0002] High-voltage diesel generator sets are independent power generation devices that use diesel or heavy oil as fuel and have voltage levels ranging from 6kV to 11kV. High-voltage diesel generators have large unit capacity and high heat load, thus requiring high heat dissipation; the heat dissipation mechanism directly affects the unit's thermal efficiency, component lifespan, load capacity, and overall stability.

[0003] Common cooling mechanisms include circulation structures and heat dissipation structures. Typically, the circulation structure is connected to the water system of the diesel generator. When the heat dissipation mechanism is activated, it drives the coolant to circulate in the water system through the circulation structure, thereby generating heat and cooling the coolant through the heat dissipation mechanism. This allows the diesel generator to be cooled and dissipated for a long time.

[0004] During the initial startup phase, the temperatures of various components of the diesel generator are relatively low (not yet at their optimal operating temperature). As the diesel generator operates for longer periods, the coolant temperature also increases. Typically, the circulation and cooling mechanisms in the heat dissipation system operate synchronously, and the generator's operation simultaneously drives the cooling system to ensure stable heat dissipation. Consequently, due to the cooling effect of the system, it takes a long time for the coolant and various components of the diesel generator to reach their optimal operating temperature. This results in a delay in power output after startup (the generator needs to wait for the water temperature to rise to the normal range before it can operate at full load) and a significant increase in fuel consumption.

[0005] The purpose of this invention is to provide a heat dissipation mechanism for a high-voltage diesel generator set to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] It also includes a ball seat; the ball seat is fixedly installed on the circulation box; a first pipeline and a second pipeline are fixedly installed on the ball seat;

[0009] The ball seat is rotatably and sealed with a ball tube, and a channel is opened in the ball tube, one end of which is connected to the first pipeline;

[0010] The first outlet pipe is connected to the first pipeline;

[0011] A liquid pump, wherein the inlet of the liquid pump is rotatably connected to the other end of the channel, and its outlet is connected to both ends of the diesel generator water circuit system, respectively, along with the inlet pipe.

[0012] A heat dissipation component includes a heat dissipation pipe, the two ends of which are respectively connected to the second liquid outlet pipe and the second pipe;

[0013] It also includes a switching component, the action of which can drive the X-ray tube to rotate, thereby disconnecting the channel from the first pipeline and connecting it to the second pipeline.

[0014] The heat dissipation mechanism of the high-voltage diesel generator set as described above includes a motor and a heat dissipation bracket fixedly installed on the circulation box. A fan is rotatably installed on the heat dissipation bracket, and the working shaft of the fan is connected to the output end of the motor via a belt.

[0015] The heat dissipation mechanism of the high-voltage diesel generator set as described above: multiple sets of fins are fixedly installed on the heat dissipation bracket; and the heat dissipation bracket is in contact with the heat dissipation pipes.

[0016] The cooling mechanism of the high-voltage diesel generator set as described above: the switching component includes a rotating shaft rotatably mounted on the circulation box, the rotating shaft being connected to the output end of the motor via a belt; a centrifugal disc is fixedly mounted on the rotating shaft, multiple sets of centrifugal blocks are slidably fitted on the centrifugal disc, and the multiple sets of centrifugal blocks are equidistantly arranged along the circumference of the centrifugal disc, and a telescopic sleeve is fixedly mounted on the centrifugal block; a sliding sleeve is sleeved on the rotating shaft, and a telescopic column that slidably fits into the telescopic sleeve is fixedly mounted on the sliding sleeve.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: In the initial stage of startup, the heat dissipation components do not work. At this time, the heat generated by the diesel generator can quickly raise the temperature of the coolant in the circulation tank to the optimal operating temperature, thereby avoiding the delay in power output after the unit starts due to the slow rise in coolant temperature in the initial stage of startup, and the significant increase in fuel consumption rate. When the coolant temperature reaches the optimal operating temperature, the heat dissipation components activate to maintain the coolant temperature, preventing the coolant temperature from being too high, which would disrupt the thermal balance between the diesel engine and the generator, leading to a decline in component performance, a shortened lifespan, or even serious failures.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0041] Please see Figures 1-6 As an embodiment of the present utility model, the heat dissipation mechanism of the high-pressure diesel generator set includes a circulation box 1, on which an inlet pipe 101, a first outlet pipe 102, and a second outlet pipe 103 are fixedly installed;

[0042] It also includes a ball seat 3; the ball seat 3 is fixedly installed on the circulation box 1; a first pipe 301 and a second pipe 302 are fixedly installed on the ball seat 3;

[0043] The ball seat 3 is rotatably and sealed with a ball tube 4, and a channel 401 is opened in the ball tube 4. One end of the channel 401 is connected to the first pipeline 301.

[0044] The first outlet pipe 102 is connected to the first pipeline 301;

[0045] The liquid pump 5 has its inlet rotatably connected to the other end of the channel 401, and its outlet is connected to both ends of the diesel generator water circuit system via the inlet pipe 101.

[0046] The heat dissipation component includes a heat dissipation pipe 2, the two ends of which are respectively connected to the second liquid outlet pipe 103 and the second pipe 302;

[0047] It also includes a switching component, which can rotate the X-ray tube 4 to disconnect the conduction state between the channel 401 and the first pipeline 301, and make it conduction between the channel 401 and the second pipeline 302.

[0048] In this embodiment, the circulation tank 1 is filled with coolant for cooling the diesel generator set.

[0049] In the initial state, one end of the first pipe 301 is connected to the channel 401, and at this time the channel 401 and the second pipe 302 are in a blocked state.

[0050] In the initial stage of diesel generator startup, the liquid pump 5 will operate, thereby drawing coolant from the circulation tank 1 through the first outlet pipe 102, and through the first pipe 301 to the channel 401, and then from the channel 401 to the inlet of the liquid pump 5, and then from the outlet into the water system of the diesel generator. The coolant flows in the water system, carrying away the heat generated by the generator operation; finally, the coolant will flow back into the circulation tank 1 through the inlet pipe 101, and the temperature of the coolant in the circulation tank 1 will increase as the working time increases.

[0051] In the initial stage of startup, the heat dissipation components are not working. At this time, the heat generated by the diesel generator can quickly raise the temperature of the coolant in the circulation tank 1 to the optimal operating temperature. This avoids the delay in power output after the unit starts due to the slow rise in coolant temperature in the initial stage of startup, and also avoids a significant increase in fuel consumption.

[0052] When the coolant temperature reaches the optimal operating temperature, the heat dissipation components activate to maintain the coolant temperature and prevent the coolant temperature from becoming too high, which could disrupt the thermal balance between the diesel engine and the generator, leading to decreased component performance, shortened lifespan, or even serious malfunctions.

[0053] When the switching component operates, it drives the ball tube 4 to rotate, thereby disconnecting the channel 401 from the first pipe 301 and connecting the channel 401 to the second pipe 302. At this time, the liquid pump 5 works, and the coolant flows from the second outlet pipe 103 into the heat dissipation pipe 2 and then into the second pipe 302. After that, it flows from the channel 401 to the inlet and from the outlet to the diesel generator water system, and finally flows back to the circulation tank 1 through the inlet pipe 101.

[0054] When the coolant flows in the heat dissipation pipe 2, some of its heat is dissipated, thereby maintaining the temperature of the coolant entering the water circuit system at the optimal operating temperature.

[0055] As a further embodiment of this utility model, the heat dissipation component also includes a motor 6 and a heat dissipation bracket 7 fixedly installed on the circulation box 1. A fan 8 is rotatably installed on the heat dissipation bracket 7, and the working shaft of the fan 8 is connected to the output end of the motor 6 by a belt.

[0056] As a further embodiment of this utility model, multiple sets of fins 701 are fixedly installed on the heat dissipation bracket 7; and the heat dissipation bracket 7 is in contact with the heat dissipation pipe 2.

[0057] In this embodiment, the heat sink bracket 7 is in contact with the heat sink pipe 2, so some of the heat from the coolant in the heat sink pipe 2 will be transferred to the heat sink bracket 7; the fins 701 can increase the transfer efficiency; when the motor 6 is working, it will drive the fan 8 to rotate through the belt, thereby increasing the air flow rate on the surface of the heat sink bracket 7, thereby improving the heat dissipation efficiency; the fins 701 can increase the contact area between the heat sink bracket 7 and the air.

[0058] When the coolant temperature reaches the optimal operating temperature, the heat dissipation components activate to maintain the coolant temperature and prevent the coolant temperature from becoming too high, which could disrupt the thermal balance between the diesel engine and the generator, leading to decreased component performance, shortened lifespan, or even serious malfunctions.

[0059] As a further embodiment of this utility model, the switching component includes a rotating shaft 9 rotatably mounted on the circulation box 1, and the rotating shaft 9 is connected to the output end of the motor 6 via a belt; a centrifugal disc 10 is fixedly mounted on the rotating shaft 9, and multiple sets of centrifugal blocks 11 are slidably fitted on the centrifugal disc 10, and the multiple sets of centrifugal blocks 11 are equidistantly arranged along the circumference of the centrifugal disc 10; a telescopic sleeve 1101 is fixedly mounted on the centrifugal block 11; a sliding sleeve 12 is sleeved on the rotating shaft 9, and a telescopic column 1201 that slidably fits into the telescopic sleeve 1101 is fixedly mounted on the sliding sleeve 12.

[0060] In this embodiment, when the motor 6 operates, it drives the rotating shaft 9 to rotate via a belt, thereby driving the centrifugal disc 10 to rotate, which in turn drives multiple sets of centrifugal blocks 11 to rotate synchronously. As the centrifugal blocks 11 rotate, they gradually move away from the rotating shaft 9 under the action of centrifugal force, thus causing the sliding sleeve 12 to gradually move away from the centrifugal disc 10 via the telescopic sleeve 1101 and the telescopic column 1201; during this process, the telescopic column 1201 slides outward within the telescopic sleeve 1101. Since the rotational speed of the motor 6 is constant, the distance traveled by the sliding sleeve 12 is also constant.

[0061] When the sliding sleeve 12 moves, it will drive the ball tube 4 to rotate, thereby causing the channel 401 to disengage from the first pipe 301. When the sliding sleeve 12 moves to the end of its stroke, the channel 401 becomes connected to the second pipe 302, and the coolant will flow in the heat dissipation pipe 2.

[0062] In the initial stage of startup, the heat dissipation components do not work. At this time, the heat generated by the diesel generator can quickly raise the temperature of the coolant in the circulation tank 1 to the optimal operating temperature. This avoids the delay in power output after the unit starts due to the slow rise in coolant temperature in the initial stage of startup, and also avoids a significant increase in fuel consumption. When the coolant temperature reaches the optimal operating temperature, the heat dissipation components activate to maintain the coolant temperature and prevent the coolant temperature from being too high, which would disrupt the thermal balance between the diesel engine and the generator, leading to a decrease in component performance, a shortened lifespan, or even serious failures.

[0063] As a further embodiment of this utility model, the switching component also includes a slip ring 14 rotatably connected to the sliding sleeve 12, and the slip ring 14 is slidably connected to the ball tube 4. A protruding post 1401 is fixedly installed on the slip ring 14; the ball tube 4 is provided with an inclined groove 402 that slidably engages with the protruding post 1401.

[0064] In this embodiment, during the movement of the sliding sleeve 12, the slip ring 14 moves synchronously, thereby causing the protruding column 1401 to slide in the inclined groove 402. Through the compression of the groove wall of the inclined groove 402 by the protruding column 1401, the ball tube 4 can be rotated, thereby causing the channel 401 to rotate, so that the channel 401 is disengaged from the first pipe 301. When the sliding sleeve 12 moves to the end of its stroke, the channel 401 is connected to the second pipe 302, at which time the coolant will flow in the heat dissipation pipe 2. When the coolant temperature reaches the optimal operating temperature, the heat dissipation component is activated to maintain the coolant temperature and avoid the coolant temperature from being too high, which would disrupt the thermal balance between the diesel engine and the generator, leading to a decrease in component performance, a shortened lifespan, or even a serious failure.

[0065] As a further embodiment of this utility model, a spring 13 is wrapped around the rotating shaft 9; the two ends of the spring 13 respectively abut against the sliding sleeve 12 and the circulation box 1.

[0066] In this embodiment, when the motor 6 rotates and drives the rotating shaft 9 to rotate, the sliding sleeve 12 will gradually move away from the centrifugal disc 10 and compress the spring 13.

[0067] When the diesel generator stops working, the motor 6 will also stop operating. At this time, the elastic force of the spring 13 will cause the sliding sleeve 12 to gradually approach the centrifugal disc 10. During this process, the telescopic column 1201 and the telescopic sleeve 1101 will drive the centrifugal block 11 to approach the rotating shaft 9 to reset. The sliding sleeve 12 will also drive the slip ring 14 to slide in the opposite direction, thereby causing the protruding column 1401 to slide in the opposite direction in the inclined groove 402. Through the squeezing action of the protruding column 1401 on the groove wall of the inclined groove 402, the ball tube 4 will rotate, so that the channel 401 is disconnected from the second pipeline 302 and connected to the first pipeline 301, thus facilitating the next start of the diesel generator.

[0068] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
