Description

Technical Field

[0001] This utility model relates to the field of generator set circulating cooling technology, and in particular to a dual-circulation mechanism for generator sets. Background Technology

[0002] A generator set is a common type of mobile power generation device, such as a common diesel generator set. This type of set generally has an external rectangular casing with an internal air-cooled heat dissipation structure.

[0003] The existing technology includes a Chinese patent with publication number CN219492398U, which discloses an air-cooled and water-cooled dual-cycle diesel generator set. It uses a dual-cycle air-cooling structure and a water-cooling structure to cool the generator set. However, the effective contact area between the water pipe and the generator set is too small, resulting in low dual-cycle efficiency. Therefore, in order to better realize the cooling function of the dual-cycle structure for the generator set, promote technological progress in the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the dual-cycle mechanism in the existing technology. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an apparatus to solve one or more problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dual-cycle mechanism for a generator set includes a housing. A top plate is fixedly connected to the top of the housing. A coolant tank and a pump body are fixedly connected to the top of the top plate. A first connecting pipe is sealed and inserted into one side of the coolant tank, and the other end of the first connecting pipe is connected to the inlet end of the pump body. A second connecting pipe is sealed and inserted into the outlet end of the pump body. A support plate is fixedly connected between the inner walls of both sides of the housing. Two support seats are fixedly connected to the top of the support plate. A cooling pipe passes between the two support seats. One end of the cooling pipe is sealed and inserted into the other end of the second connecting pipe. A third connecting pipe is sleeved on the other end of the cooling pipe. The other end of the third connecting pipe is sealed and inserted into the top of the coolant tank. Multiple ventilation openings are provided at one end of the housing. An exhaust fan is fixedly connected to the bottom of the support plate, and an intake fan is fixedly connected to the top of the support plate.

[0006] Furthermore, the bottom fixed connecting block of the housing has a base, and the bottom fixed connecting block of the base has multiple casters.

[0007] Furthermore, a dustproof net is fixed to the inner wall of one end of the housing, and the dustproof net is located inside the vent.

[0008] Furthermore, the outer wall of one end of the housing has a fixed connecting block with multiple rain covers, which are located outside the vent.

[0009] Furthermore, the top plate has a connecting cylinder as its top fixed connecting block, and a top cover is rotatably connected to the top of the connecting cylinder.

[0010] Furthermore, a fixing cylinder is snapped into one end of the coolant tank, and a semiconductor cooling chip and a conductive plate are snapped into the fixing cylinder, with the heat-absorbing end of the semiconductor cooling chip in contact with the conductive plate.

[0011] Furthermore, the top fixed connecting block of the top plate has a cooling fan, which is located on one side of the heating end of the semiconductor cooling chip.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. By pumping the coolant from the coolant tank into the first connecting pipe and then into the cooling pipe through the second connecting pipe, the cooling pipe, located inside the housing, can exchange heat with the air inside the housing, reducing the overall temperature inside the housing. At the same time, it can also cool the passing gas, and then use the cooled gas to dissipate heat from the generator set. This combines water cooling and air cooling to cool the generator set, improving the cooling effect and avoiding the insufficient contact surface of the generator set in the existing water cooling method.

[0013] 2. By pumping the coolant from the coolant tank into the first connecting pipe, and then through the second connecting pipe into the cooling pipe to cool the passing gas, the heated coolant returns to the coolant tank through the third connecting pipe, thus achieving recycling and saving resources.

[0014] 3. The temperature of the coolant in the coolant tank is absorbed by the heat-absorbing end of the semiconductor refrigeration chip, thereby cooling the coolant for subsequent use. Attached Figure Description

[0018] Reference Figures 1-6 A dual-cycle mechanism for a generator set includes a housing 1, a top plate 101 fixed to the top of the housing 1 by bolts, a coolant tank 2 and a pump body 3 fixed to the top of the top plate 101 by bolts, an inlet pipe welded to the top of the coolant tank 2, and a sealing cap threaded to the top end of the inlet pipe. like Figure 2 and Figure 3As shown, a first connecting pipe 7 is sealed and inserted into one side of the coolant tank 2. The other end of the first connecting pipe 7 is connected to the inlet end of the pump body 3. A second connecting pipe 8 is sealed and inserted into the outlet end of the pump body 3. A support plate 4 is fixed between the inner walls of both sides of the housing 1 by bolts. The support plate 4 is a heat-conducting plate structure, such as an aluminum metal plate. Two support seats 5 are fixed to the top of the support plate 4 by bolts. A cooling pipe 6 is inserted between the two support seats 5. One end of the cooling pipe 6 is sealed and inserted into the other end of the second connecting pipe 8. A third connecting pipe 9 is sleeved on the other end of the cooling pipe 6. The other end of the third connecting pipe 9 is sealed and inserted into the top of the coolant tank 2. Under the action of the pump body 3, the coolant in the coolant tank 2 is drawn into the first connecting pipe 7, and then input into the cooling pipe 6 through the second connecting pipe 8. The cooling pipe 6 is located inside the housing 1 and can exchange heat with the air inside the housing 1 to reduce the overall temperature inside the housing 1. At the same time, it also cools the passing gas. The heated coolant returns to the coolant tank 2 through the third connecting pipe 9, thereby realizing the circulation. like Figure 4 and Figure 5 As shown, one end of the housing 1 is provided with multiple ventilation openings 10. The bottom of the support plate 4 is fixed with an exhaust fan 11 by bolts, and the top of the support plate 4 is fixed with an intake fan 12 by bolts. Under the action of the intake fan 12, gas is drawn into the housing 1 from the ventilation openings 10. After the gas is cooled by the cooling pipe 6, it flows to the generator set, thereby cooling the generator set. At the same time, the flow of gas carries away some of the heat of the generator set, and the heat is discharged from the ventilation openings 10 under the action of the exhaust fan 11. A dustproof net 14 is fixed to the inner wall of one end of the housing 1 by bolts. The dustproof net 14 is located inside the ventilation port 10 to prevent dust from entering the housing 1 and thus avoid affecting the heat dissipation and cooling of the generator set. A connecting cylinder 16 is welded to the top of the top plate 101, and a top cover 17 is rotatably connected to the top of the connecting cylinder 16. Multiple rain covers 15 are welded to the outer wall of one end of the housing 1. The rain covers 15 are located outside the vent 10 to prevent rainwater from entering the housing 1. like Figure 6 As shown, a fixed cylinder 18 is snapped onto one end of the coolant tank 2. A semiconductor cooling chip 19 and a conductive plate 20 are fixed inside the fixed cylinder 18. The conductive plate 20 is made of a material with good thermal conductivity, such as oxygen-free copper or aluminum. The heat-absorbing end of the semiconductor cooling chip 19 contacts the conductive plate 20, and the temperature of the coolant is transferred to the conductive plate 20 and finally absorbed by the heat-absorbing end of the semiconductor cooling chip 19, thereby cooling the coolant. A cooling fan 21 is fixed to the top of the top plate 101 by bolts. The cooling fan 21 is located on one side of the heat dissipation end of the semiconductor cooling chip 19. Under the action of the cooling fan 21, the heat is blown away, thereby achieving the effect of heat dissipation and cooling. The bottom of the housing 1 is fixed to the base 13 by bolts. The bottom of the base 13 is fixed with multiple casters by bolts. The casters are equipped with brake wheels to facilitate the movement of the generator set.

[0019] The working principle of this embodiment is as follows: When in use, the generator set is installed on the base 13. First, under the action of the pump body 3, the coolant in the coolant tank 2 is drawn into the first connecting pipe 7, and then input into the cooling pipe 6 through the second connecting pipe 8. At the same time, under the action of the suction fan 12, the gas is drawn into the housing 1 from the vent 10. When the gas passes through the cooling pipe 6, the low temperature in the cooling pipe 6 is transferred to the gas, thereby cooling the gas. Then, the cooled gas passes through the generator set, and the low temperature of the gas is transferred to the generator set, thereby cooling the generator set. At the same time, the flow of gas carries away some of the heat of the generator set. Then, under the action of the exhaust fan 11, the heat is discharged from the vent 10. After being heated, the coolant returns to the coolant tank 2 through the third connecting pipe 9. The heat-absorbing end of the semiconductor refrigeration chip 19 absorbs the temperature of the coolant through the conductive plate 20, thereby cooling the coolant. At the same time, the heat-dissipating end of the semiconductor refrigeration chip 19 dissipates the heat, which is then blown away by the cooling fan 21, thus achieving the effect of heat dissipation and cooling.

[0020] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0021] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
