Description

Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a heat dissipation structure of a generator set. Background Art

[0002] Generator sets generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it may cause equipment overheating, damage, or even safety accidents. Therefore, heat dissipation of generator sets is one of the important measures to ensure the normal operation of equipment. The main principle of heat dissipation of generator sets is to dissipate the generated heat into the surrounding environment through the heat dissipation system.

[0003] At present, some cooling systems generally adopt liquid cooling, connecting the radiator and the engine, circulating the coolant in the engine and the radiator through a liquid pump, and then cooling the radiator through a fan. However, this cooling process is indeed accompanied by the problem of heat waste, causing unnecessary losses. Existing engines are generally ignited by spark plugs, and the spark plugs need to be connected to batteries. The current method of charging batteries is to connect the batteries to generators for charging. Some methods require the batteries to be removed for charging. Both of the above methods will cause energy waste and are cumbersome to operate. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] This embodiment relates to a heat dissipation structure of a generator set 3, the overall structure of which is as follows: Figure 1 As shown, it includes a base 1, a backflow box 4, a heat dissipation component 6, and fan blades 8.

[0034] Among them, the engine 2 and the generator 3 are fixedly arranged on the base 1, the driving shaft of the engine 2 is fixedly connected to the generator 3, the backflow box 4 is connected to the engine 2, the base 1 is fixedly arranged with a vertical plate 5, the backflow box 4 is fixedly arranged on the vertical plate 5, the heat dissipation component 6 is fixedly arranged on the backflow box 4, the heat dissipation component 6 is fixedly arranged on the backflow box 4 through a locking member 7, the backflow box 4 is fixedly arranged on the vertical plate 5 through a locking member 7, the fan blade 8 is located on the side of the heat dissipation component 6 away from the engine 2, and the fan blade 8 is driven by the driving shaft of the engine 2.

[0035] It is worth mentioning that the engine 2 can select a diesel engine 2, and the generator 3 is driven to rotate by the driving shaft of the engine 2 to complete the power generation. This method is a common generator 3 group in the prior art and will not be repeated here. The guide box is used to store coolant. The liquid pump on the engine 2 drives the coolant to flow inside the engine 2 and the backflow box 4. The backflow box 4 is installed on the vertical plate 5 to ensure that the backflow box 4 is installed vertically, which is convenient for the fan blades 8 to cool the backflow box 4. The heat dissipation component 6 is attached to the backflow box 4, and the fan blades 8 can further dissipate the heat of the backflow box 4. In addition, the heat dissipation component 6 is electrically connected to the battery of the engine 2 to ensure that the heat dissipation component 6 can charge the battery. The fan blades 8 are driven by the driving shaft of the engine 2. Such an arrangement can reduce the use of a driving member alone to drive the fan blades 8. The heat dissipation component 6 and the backflow box 4 can be fixed to the vertical plate 5 by a locking member 7. Such an arrangement can facilitate disassembly and assembly, and facilitate the inspection and maintenance of the heat dissipation component 6.

[0036] Based on the above overall introduction, an exemplary structure of the heat dissipation structure of the generator 3 group of this embodiment is as follows: Figure 2 and Figure 3 As shown, the engine 2 is provided with an inlet pipe 9 and an outlet pipe 10 for circulating the coolant, and the inlet pipe 9 and the outlet pipe 10 are respectively connected to the backflow box 4. An opening 11 is provided on the vertical plate 5, and the heat dissipation component 6 passes through the opening 11. It should be noted that the inlet pipe 9 and the outlet pipe 10 are respectively connected to the upper and lower sides of the backflow bin, and such a setting can ensure that the coolant circulates in the backflow box 4, so that the heat dissipation component 6 dissipates heat from the backflow box 4. The setting of the opening 11 can ensure that the heat dissipation component 6 passes through, which is convenient for the fan blades 8 to dissipate heat from the heat dissipation component 6. In addition, it is convenient for the locking member 7 to fix the heat dissipation component 6 and the backflow box 4 on the vertical plate 5.

[0037] As a preferred embodiment, Figure 5As shown, in this embodiment, the heat dissipation assembly 6 includes a power generation sheet 601 attached to the side of the backflow box 4, and a heat sink 602 attached to the power generation sheet 601, and the power generation sheet 601 is electrically connected to the battery. A groove 603 is provided on the backflow box 4, and the power generation sheet 601 and the heat sink 602 are stacked and arranged in the groove 603.

[0038] It should be noted that the power generation sheet 601 is a temperature difference power generation sheet 601. The temperature difference power generation sheet 601 generates electricity by using the temperature difference effect. Therefore, the power generation sheet 601 is installed in the backflow box 4. When the coolant flows into the backflow box 4 from the liquid inlet, the coolant is in a high temperature state. Therefore, it can be ensured that one end of the power generation sheet 601 is a heat source, and the other end of the power generation sheet 601 is exposed to the air and cooperates with the heat sink 602 to ensure that the other end of the power generation sheet 601 is a cold source. Therefore, the power generation sheet 601 generates a temperature difference to generate electricity. In order to facilitate the installation of the power generation sheet 601 and the stability after installation, a groove 603 is opened on the backflow box 4, and the power generation sheet 601 and the heat sink 602 are placed in the groove 603, and then fixed by the locking member 7 to ensure that the power generation sheet 601 and the heat sink 602 can be fixed on the backflow box 4, and the high-temperature coolant can be cooled after being heated by the power generation sheet 601 to generate electricity, and then discharged through the liquid outlet.

[0039] As a preferred embodiment, Figure 4 As shown, in this embodiment, the locking member 7 includes a clamping ring 701 fixedly arranged on the backflow box 4, and a locking block 702 inserted in the clamping ring 701, the locking block 702 abuts against the vertical plate 5, and the side of the locking block 702 facing away from the vertical plate 5 is set as an inclined surface, and the inclined surface is inserted in the clamping ring 701. A cushion block 703 is arranged between the locking block 702 and the vertical plate 5, and the power generation sheet 601 and the heat sink 602 are arranged between the locking block 702 and the backflow box 4.

[0040] It should be noted that the clamping rings 701 are fixedly installed on the left and right sides of the reverse flow box 4. The locking blocks 702 are inserted into the clamping rings 701. One side of the locking block 702 abuts against the vertical plate 5, and the other side of the locking block 702 abuts against the clamping ring 701. In this way, the reverse flow box 4 can be fixed on the vertical plate 5. The side of the locking block 702 that abuts against the clamping ring 701 is set as an inclined surface. The purpose is to ensure that the greater the insertion into the clamping ring 701, the greater the locking force, ensuring the stability of the reverse flow box 4. The cushion block 703 is fixedly installed on the vertical plate 5, and the vertical plate 5 can also ensure the stability of the reverse flow box 4 fixed on the vertical plate 5. Moreover, the setting of the cushion block 703 can also ensure that the power generation piece 601 and the heat dissipation plate are located between the locking block 702 and the reverse flow box 4, that is, the power generation piece 601 and the heat dissipation fin 602 are clamped therebetween, and the fixing strength is ensured, so as to realize that the locking member 7 fixes the heat dissipation assembly 6 and the reverse flow box 4 on the vertical plate 5 at the same time. In order to prevent the locking block 702 from sliding automatically, a clamping block is provided at the bottom of the locking block 702, and a clamping groove 16 is provided on the cushion block 703. After the locking block 702 is inserted into the clamping ring 701, the clamping block is inserted into the clamping groove 16 to prevent the locking block 702 from sliding automatically.

[0041] Preferably, as Figure 2 and Figure 3 shown, a first pulley 12 is fixedly arranged on the drive shaft of the engine 2 in this embodiment. A transmission shaft 14 is rotatably arranged on the base 1. Second pulleys 13 are respectively arranged at both ends of the transmission shaft 14 and the central axis of the fan blade 8. One of the second pulleys 13 on the first pulley 12 and the transmission shaft 14 is connected by a belt, and the other second pulley 13 on the transmission shaft 14 and the second pulley 13 on the fan blade 8 are connected by a belt.

[0042] Specifically, the first pulley 12 is key-connected to the drive shaft of the engine 2. Since there is a reverse flow box 4 between the drive shaft of the engine 2 and the fan blade 8, it is necessary to add a transmission shaft 14 to drive the fan blade 8, so as to avoid adding a driving part to drive the fan blade 8. The transmission shaft 14 is rotatably connected to the base 1 through a bearing. Two second pulleys 13 are rotatably connected to the transmission shaft 14, and one second pulley 13 is key-connected to the central axis of the fan blade 8. That is, the first pulley 12 on the drive shaft of the engine 2 drives one of the second pulleys 13 on the transmission shaft 14 to rotate, so that the transmission shaft 14 and the other second pulley 13 on the transmission shaft 14 rotate. This second pulley 13 drives the second pulley 13 on the fan blade 8 to rotate, and then the fan blade 8 rotates. The fan blade 8 needs to be installed on the vertical plate 5 through the cross beam 15. The cross beam 15 is in a C shape. In this way, it is ensured that the heat dissipation assembly 6 can be installed in the C-shaped cross beam 15. The central axis of the fan blade 8 is rotationally connected to the cross beam 15 to ensure that the fan blade 8 can rotate, so as to dissipate heat from the heat dissipation fin 602.

[0043] The heat dissipation structure of the generator group 3 in this embodiment ensures that the heat energy of the engine 2 can be converted into electrical energy for charging through the coordinated arrangement of the backflow box 4 and the generator sheet 601, thereby reducing other charging methods and reducing heat waste. The coordinated arrangement of the heat dissipation component 6 and the fan blade 8 ensures that the temperature difference between the cold source and the heat source at both ends of the generator sheet 601 becomes larger, thereby improving the power generation efficiency. The arrangement of the locking member 7 ensures that the generator sheet 601 is easy to disassemble and assemble, thereby facilitating maintenance and improving installation efficiency.

[0044] The above description is only a preferred embodiment of the present invention and is 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.
