Abstract
Description
Technical Field
[0001] This application relates to the field of diesel generator sets, specifically to a silent containerized diesel generator set with good water cooling performance. Background Technology
[0002] Modern containerized diesel generator sets typically employ a design where an open-type diesel generator set is installed inside a container.
[0003] Chinese patent document CN219139196U discloses a containerized diesel generator set, including a container body. Inside the container body is a base, and the diesel generator set body is mounted on the surface of the base. The diesel generator set body is located inside the container body. A high-efficiency heat dissipation mechanism is located at the top of the container body, consisting of a drive assembly and a cooling fan. Maintenance mechanisms are located at both ends of the base, consisting of a moving channel and a guide assembly. A fuel level observation mechanism is located inside the container body, consisting of an observation component, a float, and a guide column. This invention not only improves the convenience of diesel generator set maintenance and heat dissipation during use, but also prevents insufficient diesel fuel during operation.
[0004] The aforementioned patent relies solely on cooling fans for heat dissipation, resulting in poor overall heat dissipation. This can easily lead to the generator set overheating inside the container, reducing its operating power, or even causing it to shut down. Utility Model Content
[0005] In order to overcome the problem of poor heat dissipation in existing containerized diesel generator sets, this application provides a silent containerized diesel generator set with good water cooling performance.
[0006] This application adopts the following technical solution: a silent containerized diesel generator set with good water cooling heat dissipation effect, including a container and a generator set body and a cooling fan installed inside the container. The side wall of the container is provided with louvers, and the cooling fan blows hot air toward the louvers. The container is also provided with a water cooling mechanism, which includes a box body. A heat conduction rod is inserted through the box body. One end of the heat conduction rod is located on one side of the box body and in contact with the generator set body, and the other end of the heat conduction rod is located on the other side of the box body.
[0007] Cooling water is stored in the lower inner part of the box, and a nozzle is provided inside the box for spraying cooling water toward the portion of the heat-conducting rod located inside the box.
[0008] Optionally, the louvers, cooling fan, and generator set body are arranged at intervals along the same straight line, and the housing is located on the outside of the generator set body.
[0009] Optionally, a plurality of perforations are symmetrically provided on a pair of side walls of the housing, and the plurality of perforations are used to install the heat-conducting rod. The heat-conducting rod is also fitted with two sealing rings, one of which is connected to one side of the inner wall of the housing, and the other of which is connected to the other side of the inner wall of the housing.
[0010] Optionally, the housing is provided with a mesh-like partition, a plurality of heat-conducting rods are located above the partition, the cooling water is stored below the partition, and the nozzle is installed on the top of the partition and points towards the heat-conducting rods;
[0011] The side wall of the enclosure is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver low-temperature cooling water into the enclosure, and the outlet pipe is used to deliver heated cooling water out of the enclosure.
[0012] Optionally, the end of the heat-conducting rod away from the generator set body is provided with a slot.
[0013] Optionally, the length of the heat-conducting rod is greater than the thickness of the housing.
[0014] Compared with the prior art, this application, while setting up a cooling fan for air cooling, can absorb the heat of the generator set body through direct contact between the heat conduction rod and the generator set body, and then transfer the heat by spraying cooling water through the heat conduction rod, thus playing the role of water cooling and greatly improving the heat dissipation effect.

[0020] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] like Figures 1-4 As shown, a quiet containerized diesel generator set with good water-cooling heat dissipation includes a container 1, a generator set body 2 and a cooling fan 3 disposed inside the container 1. Louvers 10 are provided on the side wall of the container 1, and the cooling fan 3 blows hot air towards the louvers 10. A water-cooling mechanism 4 is also provided inside the container 1. The water-cooling mechanism 4 includes a housing 41, and a heat-conducting rod 42 passes through the housing 41. One end of the heat-conducting rod 42 is located on one side of the housing 41 and contacts the generator set body 2, while the other end is located on the other side of the housing 41. Cooling water is stored in the lower inner part of the housing 41, and a nozzle 43 is provided inside the housing 41 for spraying cooling water towards the portion of the heat-conducting rod 42 located inside the housing 41.
[0022] The cooling fan 3 can provide air cooling for the generator set body 2. At the same time, the heat-conducting rod 42 is in direct contact with the generator set body 2 and can absorb the heat generated by the generator set body 2. The heat-conducting rod 42 can be made of a material with good thermal conductivity. In this way, the heat absorbed by the heat-conducting rod 42 can be quickly transferred inside the heat-conducting rod 42. At this time, the nozzle 43 will spray the part of the heat-conducting rod 42 inside the housing 41 with cool water at a lower temperature to cool down the heat-conducting rod 42, thereby achieving heat transfer and realizing water cooling effect, which greatly improves the overall heat dissipation effect.
[0023] The louvers 10, cooling fan 3, and generator body 2 are arranged at intervals along the same straight line, making the airflow more linear and thus improving the air cooling effect. The housing 41 is located on the outside of the generator body 2, thus ensuring that the housing 41 does not affect the airflow, so that air cooling and water cooling complement each other.
[0024] The housing 41 has a plurality of symmetrical perforations 411 on its two side walls. These perforations 411 are used to install the heat-conducting rod 42. Two sealing rings 421 are fitted onto the heat-conducting rod 42. One sealing ring 421 is connected to one side of the inner wall of the housing 41, and the other sealing ring 421 is connected to the other side of the inner wall of the housing 41. The sealing rings 421 ensure that cooling water does not leak out through the gap between the heat-conducting rod 42 and the perforations 411. Simultaneously, the friction between the sealing rings 421 and the heat-conducting rod 42 helps to limit the movement of the heat-conducting rod 42, thus ensuring that the heat-conducting rod 42 can reliably fit against the generator body 2, thereby guaranteeing the reliable heat conduction effect of the heat-conducting rod 42.
[0025] The housing 41 contains a mesh-like partition 412. Several heat-conducting rods 42 are located above the partition 412, and cooling water is stored below it. A nozzle 43 is mounted on top of the partition 412 and points towards the heat-conducting rods 42. This ensures reliable nozzle installation and filters the returning cooling water. Furthermore, a water pump can be installed inside the housing 41, kept submerged in cooling water. The pump is connected to the nozzle 43 via a water pipe, ensuring continuous and abundant water spraying from the nozzle 43 to the heat-conducting rods 42. The side wall of the housing 41 also has an inlet pipe 413 and an outlet pipe 414. The inlet pipe 413 supplies low-temperature cooling water into the housing 41, while the outlet pipe 414 supplies warmer cooling water to the outside of the housing 41. This ensures the cooling water inside the housing 41 remains at a low temperature, thus guaranteeing reliable water cooling performance.
[0026] The heat-conducting rod 42 has a slot 422 at the end furthest from the generator set body 2. When pushing the heat-conducting rod 42, an extension rod or other auxiliary tool can be inserted into the slot 422 to reduce the difficulty of pushing the heat-conducting rod 42. Moreover, the slot 422 increases the overall surface area of the heat-conducting rod 42, thereby improving the efficiency of heat radiation from the heat-conducting rod 42 and further improving the heat dissipation effect. At the same time, depending on the shape of the generator set body 2, the heat-conducting rod 42 at different positions needs to be pushed a different distance, thereby ensuring that the heat-conducting rod 42 is reliably fitted to the generator set body 2.
[0027] The length of the heat-conducting rod 42 is greater than the thickness of the housing 41. This ensures that after the heat-conducting rod 42 comes into contact with the generator body 2, the end of the heat-conducting rod 42 that is away from the generator body 2 is still located outside the housing 41, which facilitates the repositioning of the heat-conducting rod 42.
[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
