Description

Technical Field

[0001] The utility model relates to the field of generator sets, in particular to a protective heat dissipation device for generator sets. Background Art

[0002] Generators generate a lot of heat when working, so it is necessary to use a heat dissipation device to dissipate heat during use to ensure the normal use of the engine. The heat dissipation methods of the generator include external cooling and internal cooling. The internal cooling method is to directly pass the treated cooling water into the hollow wire of the rotor excitation winding or stator winding coil to take away the heat generated by the loss. A heat dissipation device for a generator is disclosed in the Chinese utility model patent with the announcement number CN219458834U. The heat dissipation device is set at one end of the installation frame, and the heat dissipation fan is installed and connected to the rotating motor through a protective net. When in use, the heat inside the heat dissipation water tank is extracted by the heat dissipation fan driven by the rotating motor, thereby achieving enhanced heat dissipation function.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, the water tank is cooled by heat dissipation wind, so that the water after heat exchange is cooled. Since the water tank is large in size and has a large amount of water inside, it is difficult to quickly cool the water inside the water tank by only setting a heat dissipation fan outside the water tank, and the water tank itself has a certain wall thickness, which will affect the temperature of the water entering the generator, resulting in a low heat dissipation effect. For this reason, we designed a protective heat dissipation device for a generator set. Utility Model Content

[0004] In order to solve the technical problem that the heat dissipation effect of the generator is not high, the utility model provides a protective heat dissipation device for a generator set.

[0005] The utility model is implemented by the following technical scheme: a protective heat dissipation device for a generator set, comprising a heat exchange tube 1, the heat exchange tube 1 is suspended and sleeved inside a flow guide outer tube, and the left front end of the heat exchange tube 1 is connected to a heat exchange tube 2, the left front end of the flow guide outer tube is connected to a flow guide tube, the heat exchange tube 2, the flow guide tube and the flow guide outer tube are all provided with a plurality of heat dissipation plates distributed at equal intervals from bottom to top, and the heat dissipation plates are installed inside an outer shell.

[0006] As a further improvement of the above scheme, two air inlets and an air outlet are provided on the front and rear sides of the outer shell, and cooling fans are installed on the two air inlets. Dust-proof nets are installed on the cooling fan and the air outlet. The cooling fan can blow air into the interior of the outer shell to increase the air flow rate, thereby enabling the outer guide tube, the guide tube and the heat exchange tube to dissipate heat quickly.

[0007] As a further improvement of the above scheme, both ends of the guide outer tube are sealed, and a water inlet pipe is welded to the left rear end of the guide outer tube, and a liquid outlet pipe is extended upward from the left rear of the heat exchange tube 1. The water inlet pipe allows cold water to enter the interior of the guide outer tube, and the other end of the water inlet pipe is connected to an external water tank and a water pump, while the liquid outlet pipe is connected to the return pipe of the generator set, which is used to cool the interior of the generator set.

[0008] As a further improvement of the above scheme, the heat exchange tube 2 is formed with a liquid inlet pipe extending upward through the top of the outer shell away from its entry end, and the liquid inlet pipe is used to be connected to the drainage pipe of the generator set, so that the higher temperature water in the generator set can be discharged and cooled, and then returned to the return pipe of the generator set through the liquid outlet pipe for cooling and heat dissipation. The guide tube is formed with a water outlet pipe extending upward through the top of the outer shell away from its entry end, and the water outlet pipe is used to be connected to an external water tank, so that a water circulation is formed, thereby continuously cooling the water flow inside the generator set.

[0009] As a further improvement of the above solution, the flow direction of the liquid inside the heat exchange tube 1 is opposite to the flow direction of the liquid inside the guide outer tube, forming convection and improving the heat exchange effect.

[0010] As a further improvement of the above scheme, the heat exchange tube 1, the heat exchange tube 2, the guide outer tube and the guide tube are all designed with a serpentine structure, and the heat exchange tube 2 and the guide tube are staggered. When the cold air blows on the guide tube and the heat exchange tube, the guide tube and the heat exchange tube alternate in sequence, and the cooling effects of the two are not much different.

[0011] As a further improvement of the above scheme, the outer ring surface of the heat exchange tube 1 is provided with a plurality of support blocks arranged along its bending direction. The heat exchange tube 1 is suspended in the middle of the guide outer tube through the plurality of support blocks. There is some space between the support blocks and the inside of the guide outer tube, which facilitates the flow of water in the gap between the guide outer tube and the heat exchange tube, and also improves the heat exchange effect.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model allows the cooling water used for cooling the inside of the generator set to flow into the heat exchange tube 1 and the heat exchange tube 2, and the heat exchange tube 1 is also sleeved in the guide outer tube, so that the cooling water can be air-cooled and water-cooled at the same time, thereby improving the cooling effect of the cooling water and achieving good heat dissipation effect inside the generator set;

[0014] 2. The flow direction of the cooling water used to cool the generator set is opposite to the flow direction of the cold water used to cool the cooling water, so that the two can convect. The closer to the inside of the generator set, the lower the cooling water temperature, which improves the heat dissipation effect inside the generator set. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 5 A protective heat dissipation device for a generator set in this embodiment includes a heat exchange tube 1 5, which is suspended and sleeved inside an outer guide tube 4, and a heat exchange tube 2 6 is connected to the left front end of the heat exchange tube 1 5, and a guide tube 7 is connected to the left front end of the outer guide tube 4. The heat exchange tube 2 6, the guide tube 7 and the outer guide tube 4 are all provided with a plurality of heat dissipation plates 3 distributed at equal intervals from bottom to top, and the heat dissipation plates 3 are installed inside an outer shell 1.

[0025] Two air inlets and an air outlet 11 are provided on the front and rear sides of the outer shell 1, and cooling fans 2 are installed on the two air inlets. Dust-proof nets are installed on the cooling fan 2 and the air outlet 11. The cooling fan 2 can blow air into the inner part of the outer shell 1 to increase the air flow rate, thereby enabling the guide outer tube 4, the guide tube 7 and the heat exchange tube 2 6 to dissipate heat quickly.

[0026] Both ends of the guide outer tube 4 are sealed, and the heat exchange tube 5 is placed at the openings above the two ends of the guide outer tube 4 for sealing, and a water inlet pipe 41 is welded to the left rear end of the guide outer tube 4, and a liquid outlet pipe 51 is extended upward from the left rear of the heat exchange tube 5. The water inlet pipe 41 allows cold water to enter the inside of the guide outer tube 4, and the other end of the water inlet pipe 41 is connected to an external water tank and a water pump, and the liquid outlet pipe 51 is connected to the return pipe of the generator set, which is used to cool the inside of the generator set.

[0027] The heat exchange tube 2 6 is formed with a liquid inlet pipe 61 extending upward through the top of the outer shell 1 away from its entry end. The liquid inlet pipe 61 is used to connect with the drainage pipe of the generator set, so that the higher temperature water in the generator set can be discharged and cooled, and then returned to the return pipe of the generator set through the liquid outlet pipe 51 for cooling and heat dissipation. The guide tube 7 is formed with a water outlet pipe 71 extending upward through the top of the outer shell 1 away from its entry end. The water outlet pipe 71 is used to connect with an external water tank to form a water circulation, so as to continuously cool the water flow inside the generator set.

[0028] The liquid flow direction inside the heat exchange tube 5 is opposite to the liquid flow direction inside the guide outer tube 4, forming convection and improving the heat exchange effect.

[0029] The heat exchange tube 1 5, the heat exchange tube 2 6, the guide outer tube 4 and the guide tube 7 are all designed in a serpentine structure, and the heat exchange tube 2 6 and the guide tube 7 are staggered. When the cold air blows on the guide tube 7 and the heat exchange tube, the guide tube 7 and the heat exchange tube alternate in sequence, and the cooling effects of the two are not much different.

[0030] The outer ring surface of the heat exchange tube 5 is provided with a plurality of support blocks arranged along its bending direction. The heat exchange tube 5 is suspended in the middle of the guide outer tube 4 through the plurality of support blocks. There is also some space between the support blocks and the guide outer tube 4, which facilitates the flow of water in the gap between the guide outer tube 4 and the heat exchange tube, and also improves the heat exchange effect.

[0031] The implementation principle of a protective heat dissipation device for a generator set in the embodiment of the present application is as follows: the cooling water inside the generator set will enter the heat exchange tube 2 6 through the liquid inlet pipe 61 after exchanging heat with the generator set, and the cooling water entering the heat exchange tube 2 6 will flow along the heat exchange tube 2 6, and will be initially cooled by the heat dissipation fan 2 while flowing in the heat exchange tube 2 6, and then will enter the heat exchange tube 1 5 and flow along the heat exchange tube 1 5, and the cold water inside an external water tank will enter the guide outer tube 4 through the water inlet pipe 41 and flow along the guide outer tube 4, which will perform secondary cooling on the cooling water in the heat exchange tube 1 5, and because the liquid flow direction inside the heat exchange tube 1 5 is opposite to the liquid flow direction inside the guide outer tube 4, they can form convection, thereby improving the heat exchange effect, and the heat dissipation fan 2 can also cool the cooling inside the guide outer tube 4 and the guide tube 7, thereby improving the subsequent cooling effect on the cooling water, so that the heat dissipation effect inside the generator set is good;

[0032] By flowing the cooling water used for cooling the inside of the generator set into the heat exchange tube 1 5 and the heat exchange tube 2 6, and the heat exchange tube 1 5 is also sleeved in the guide outer tube 4, the cooling water can be air-cooled and water-cooled at the same time, thereby improving the cooling effect of the cooling water and achieving good heat dissipation effect inside the generator set;

[0033] The flow direction of the cooling water used to cool the generator set is opposite to the flow direction of the cold water used to cool the cooling water, so that the two can convect and the cooling water temperature is lower the closer to the inside of the generator set, thereby improving the heat dissipation effect inside the generator set.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
