Description
Technical Field
[0001] The utility model belongs to the technical field of generators, in particular to a top heat dissipation structure of a generator. Background Technique
[0002] Existing generator sets driven by small internal combustion engines are more and more widely used in people's lives. During the operation of the generator sets, carbon monoxide gas will inevitably be generated. Carbon monoxide is a colorless and odorless poisonous gas. The monitoring of carbon monoxide gas is realized by using a carbon monoxide alarm. When the concentration of carbon monoxide exceeds the alarm limit of the carbon monoxide alarm, the carbon monoxide alarm will cause the internal combustion engine power to shut down and stop running. However, when the carbon monoxide concentration in the external environment of the generator exceeds the standard, there will be a risk of poisoning for the operator. Generally, the traditional generator sets set the carbon monoxide alarm inside the generator set. When the carbon monoxide inside the generator set cannot be discharged in time, the generator will be mis-triggered to stop; Secondly, during the operation of the generator, the power assembly generates heat, and this heat is discharged outward through the internal exhaust system. When the generator stops running, the exhaust system also stops working. At this time, the power assembly is still dissipating heat, and the heat generated by the power assembly flows upward and accumulates at the positioning position inside the generator. Since the carburetor is generally arranged at the top position or near the top position inside the generator, the gasoline in the carburetor vaporizes when the temperature of the carburetor rises, and the restart of the generator requires the gasoline in the carburetor to be in a liquefied state, which affects the secondary start of the generator. Content of the Utility Model
[0003] The purpose of the utility model is to propose a top heat dissipation structure of a generator for the existing technologies with the above problems. The technical problem to be solved by the utility model is: how to solve the problems of mis-triggered shutdown of the generator set and affecting the secondary start of the generator set.
[0004] The purpose of the utility model can be realized by the following technical solutions:
[0005] A top heat dissipation structure of a generator, including a generator housing, an internal combustion engine power assembly is arranged inside the generator housing. It is characterized in that a heat dissipation hole is opened on the side surface of the top of the generator housing, and the heat dissipation hole is communicated with the inside of the generator housing.
[0006] In this structure, after heat dissipation holes are opened on the top of the generator casing, during the operation of the generator, part of the carbon monoxide inside the generator casing is discharged outwardly along with the exhaust system, and part of the carbon monoxide flows upward with the hot air and is discharged outwardly from the heat dissipation holes, thereby reducing the carbon monoxide concentration inside the generator casing when the generator is working, and avoiding the problem of false triggering and shutdown of the generator; secondly, when the generator is shut down, the heat generated by the internal combustion engine powertrain flows upward, so that the heat at the top of the generator casing can be discharged outwardly through the heat dissipation holes, reducing the temperature inside the generator casing, ensuring that the gasoline inside the carburetor is in a liquefied state, and thus ensuring that the generator can be smoothly started a second time; in addition, arranging the heat dissipation holes on the side of the top of the generator casing has a certain waterproof effect, making it difficult for water to enter the interior of the generator casing through the heat dissipation holes.
[0007] In the above-mentioned top heat dissipation structure of a generator, the generator housing includes a top cover, the end of the top cover has a clearance groove, the clearance groove has a mounting shaft penetrating the generator housing, and the inner side of the clearance groove is provided with the heat dissipation hole. Through the arrangement of this structure, the heat dissipation hole is arranged on the inner side of the clearance groove, which is relatively hidden, has a better waterproof effect on the one hand, and does not affect the overall appearance of the generator on the other hand.
[0008] In the above-mentioned top heat dissipation structure of a generator, the mounting shaft clearance groove has a mounting wall for the mounting shaft to pass through, and the heat dissipation hole is opened on the mounting wall, and the heat dissipation hole is located below the mounting shaft. Through the arrangement of this structure, the mounting shaft plays a certain shielding role on the heat dissipation hole, further reducing the probability of rainwater entering the heat dissipation hole and improving the waterproof effect.
[0009] In the above-mentioned top heat dissipation structure of a generator, the generator housing includes a side plate, and the outer surface of the upper end of the side plate is provided with the heat dissipation holes. This structure adopts the method of opening heat dissipation holes at multiple positions of the generator housing, which makes the heat dissipation holes more dispersed and improves the waterproof performance, and also increases the number of heat dissipation holes, which is conducive to improving the heat dissipation effect and the carbon monoxide discharge effect.
[0010] In the above-mentioned top heat dissipation structure of a generator, the upper end of the side plate has a connecting wall for the installation shaft to pass through, and the heat dissipation hole is opened on the connecting wall. This position is relatively hidden, which has a good waterproof effect on the one hand, and does not affect the overall appearance of the generator on the other hand.
[0011] In the above-mentioned top heat dissipation structure of a generator, the heat dissipation hole comprises a groove formed by being sunken inward, and a through hole is opened at the top of the groove. The heat dissipation hole of this structure has a good waterproof effect, and rainwater is not easy to enter the interior of the generator housing through the heat dissipation hole.
[0012] Compared with the prior art, the top heat dissipation structure of the generator of the present utility model has the following advantages: A part of the carbon monoxide in the generator housing of this structure flows upward with the hot air and is discharged outward through the heat dissipation holes, thereby reducing the concentration of carbon monoxide inside the generator housing during operation and avoiding the problem of mis-triggered shutdown of the generator; Secondly, after the generator stops running, the heat generated by the internal combustion engine power assembly flows upward, enabling the heat at the top inside the generator housing to be discharged outward through the heat dissipation holes, reducing the temperature inside the generator housing, ensuring that the gasoline inside the carburetor is in a liquefied state, and thus ensuring that the generator can be successfully restarted for the second time; In addition, setting the heat dissipation holes on the side of the top of the generator housing has a certain waterproof effect, making it difficult for water to enter the inside of the generator housing through the heat dissipation holes.

[0019] The following are specific embodiments of the present utility model in combination with the accompanying drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.
[0020] As Figures 1 to 5As shown in the figure, the top heat dissipation structure of the generator includes a generator housing 1. An internal combustion engine power assembly is arranged inside the generator housing 1. A heat dissipation hole 2 is formed on the side of the top of the generator housing 1, and the heat dissipation hole 2 communicates with the inside of the generator housing 1. In this structure, after the heat dissipation hole 2 is formed on the top of the generator housing 1, during the operation of the generator, part of the carbon monoxide inside the generator housing 1 is discharged outward along with the exhaust system, and another part of the carbon monoxide flows upward along with the hot air and is discharged outward from the heat dissipation hole 2, thereby reducing the concentration of carbon monoxide inside the generator housing 1 during the operation of the generator and avoiding the problem of mis-triggered shutdown of the generator; secondly, after the generator stops, the heat generated by the internal combustion engine power assembly flows upward, so that the heat at the top inside the generator housing 1 can be discharged outward through the heat dissipation hole 2, reducing the temperature inside the generator housing 1 and ensuring that the gasoline inside the carburetor is in a liquefied state, thereby ensuring that the generator can be successfully restarted for the second time; in addition, arranging the heat dissipation hole 2 on the side of the top of the generator housing 1 has a certain waterproof effect, making it difficult for water to enter the inside of the generator housing 1 through the heat dissipation hole 2.
[0021] As Figure 1 and Figure 2 shown, the generator housing 1 includes a top cover 3. The end of the top cover 3 has a relief groove 30. An installation shaft 4 passing through the generator housing 1 is arranged in the relief groove 30, and the heat dissipation hole 2 is formed on the inner side surface of the relief groove 30. In this embodiment, the relief groove 30 has an installation wall 31 for the installation shaft 4 to pass through. The heat dissipation hole 2 is formed on the installation wall 31, and the heat dissipation hole 2 is located below the installation shaft 4. The installation shaft 4 plays a certain role in blocking the heat dissipation hole 2, further reducing the probability of rainwater entering the heat dissipation hole 2 and improving the waterproof effect.
[0022] As Figure 1 , Figure 3 and Figure 4 shown, the generator housing 1 includes a side plate 5. The heat dissipation hole 2 is formed on the outer side surface of the upper end of the side plate 5. In this embodiment, the upper end of the side plate 5 has a connection wall 50 for the installation shaft 4 to pass through, and the heat dissipation hole 2 is formed on the connection wall 50. This structure adopts the heat dissipation holes 2 formed at multiple positions on the generator housing 1. On the one hand, the heat dissipation holes 2 are relatively scattered, improving the waterproof performance, and on the other hand, the number of the heat dissipation holes 2 is also increased, which is beneficial to improving the heat dissipation effect and the carbon monoxide discharge effect.
[0023] As Figure 5 shown, the heat dissipation hole 2 includes a groove 20 formed by inward depression. A through hole 21 is formed on the top inside the groove 20. The heat dissipation hole 2 designed in this way has a good waterproof effect, and it is not easy for rainwater to enter the inside of the generator housing 1 through the heat dissipation hole 2. In this embodiment, the heat dissipation hole 2 on the side plate 5 adopts this design. Of course, all the heat dissipation holes 2 can also adopt this design.
[0024] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
