Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and more specifically, to a heat dissipation structure and a compressor for a hybrid vehicle. Background Art

[0002] A hybrid vehicle is a vehicle that uses an internal combustion engine and an electric motor as dual power sources to achieve higher fuel efficiency and lower environmental pollution. In a system where the internal combustion engine and the electric motor work together, the internal combustion engine usually serves as the main power source and provides power during high-speed driving or heavy-load working conditions, while the electric motor plays a role during starting, accelerating or light-load working conditions. At the same time, during braking or decelerating, kinetic energy is converted into electrical energy and stored through an energy recovery system.

[0003] The hybrid system not only optimizes the use of energy, reduces the dependence on fossil fuels, improves fuel economy, but also reduces exhaust emissions. However, since the two power systems of the internal combustion engine and the electric motor require a large amount of space, it will cause the interior space of the vehicle to be tense. Especially in the engine compartment, the space limitation will increase heat accumulation, thereby affecting the efficiency of the heat dissipation system. Both the internal combustion engine and the electric motor generate heat during operation, especially during high-load operation. If the heat accumulation of the two power systems is not effectively managed and dissipated, it may cause component overheating, affecting performance and lifespan. In addition, in order to improve system integration, the specifications of the condenser in the air conditioning system may be sacrificed, further exacerbating the heat management problem.

[0004] In a high-temperature and high-load environment, the compressor needs to bear a greater workload to maintain the vehicle interior temperature, reducing the operating stability of the compressor, and even causing the controller to be overheated and overloaded or to fail. Therefore, a new solution needs to be proposed to solve the problem that the current heat dissipation effect of the compressor controller is poor and the compressor may overheat or even fail in a high-pressure and high-load environment. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a heat dissipation structure and a compressor for a hybrid vehicle, so as to optimize the heat dissipation effect of the compressor controller and reduce the probability of the compressor overheating or even failing in a high-pressure and high-load environment through the structural arrangement.

[0006] The above technical object of the present utility model is achieved through the following technical solutions: a heat dissipation structure, including a controller assembly and an air intake cavity. The controller assembly includes a controller housing, the controller housing is provided with a controller cavity, the air intake cavity is located on the side of the controller housing away from the controller cavity, the outer wall of the controller housing facing the air intake cavity is an installation surface, a heat exchange component is arranged on the installation surface, the heat exchange component is located in the air intake cavity, the heat exchange component includes a first heat exchange part and a second heat exchange part, and the height of the second heat exchange part in the direction perpendicular to the installation surface is lower than the height of the first heat exchange part.

[0007] The present utility model is further provided that: the first heat exchange part has a first heat exchange channel.

[0008] The present utility model is further provided that: a bearing installation part protruding from the installation surface is arranged at the central position of the installation surface, a plurality of first arc parts protruding from the installation surface are arranged on the installation surface, and the first heat exchange channel is formed between adjacent first arc parts, between the first arc part and the bearing installation part, or between the first arc part and the outer wall of the air intake cavity.

[0009] The present utility model is further provided that: the centers of the first arc parts are concentric with the bearing installation part.

[0010] The present utility model is further provided that: the second heat exchange part has a second heat exchange channel.

[0011] The present utility model is further provided that: an installation groove recessed from the installation surface is formed on the installation surface, a second arc part protruding from the bottom of the installation groove is arranged in the installation groove, and the second heat exchange channel is formed between adjacent second arc parts, between the second arc part and the bearing installation part, or between the second arc part and the outer wall of the air intake cavity.

[0012] The present utility model is further provided that: a reinforcing rib is arranged between two adjacent second arc parts, one end of the reinforcing rib is connected to the second arc part, and the other end of the reinforcing rib is connected to the second arc part, the bearing installation part, or the outer wall of the air intake cavity.

[0013] The present utility model is further provided that: the height of the reinforcing rib is lower than the height of the second arc part.

[0014] The present utility model also discloses a compressor for a hybrid vehicle, including the heat dissipation structure described in any one of the above and a compressor housing. The compressor housing is fixedly connected to the controller housing. An air inlet is formed on one side of the second heat exchange part and the air inlet is inclined towards the installation groove, and the air inlet is located on the side of the air intake cavity.

[0015] The present utility model is further configured such that when the compressor is in a working state, the heat-conducting medium entering the air intake chamber flows in from the air intake port and sequentially passes through the second heat exchange part and the first heat exchange part.

[0016] In summary, the present utility model has the following beneficial effects:

[0017] It can optimize the heat dissipation effect of the compressor controller and reduce the probability of overheating or even failure of the compressor in a high-pressure and high-load environment.

[0018] 1. Through the arrangement of the first heat exchange part and the second heat exchange part, the contact area between the heat-conducting medium and the controller bottom plate can be increased, and the heat transfer speed can be accelerated. This not only promotes the rapid external transfer of heat but also enables the heat exchange component to more effectively absorb the heat generated by the controller, thereby improving the overall heat dissipation efficiency.

[0019] 2. Since the height of the second heat exchange part is lower than that of the first heat exchange part and the housing is thinner, the path length of heat transfer is reduced. During the operation of the compressor, the gas enters through the air intake port opened on the side of the air intake chamber. The heat-conducting medium entering the air intake chamber first enters the second heat exchange part and then flows to the first heat exchange part. Such a flow design is conducive to more fully absorbing the heat generated during the operation of the controller, thereby reducing the risk of overheating of the controller.

[0020] 3. The addition of the reinforcing rib not only increases the structural strength of the heat exchange component but also compensates for the strength loss caused by the concave of the second heat exchange part, preventing possible damage to the housing under the airflow impact of the intake pressure. It also increases the residence time of the heat-conducting medium and expands the heat dissipation area, further promoting the improvement of the heat dissipation efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown, the hybrid vehicle compressor includes a heat dissipation structure and a compressor housing. The compressor housing is fixedly connected to the controller housing 21, and the connection methods include but are not limited to screwing, clamping, etc. A compression chamber is formed in the compressor housing, and components such as a motor and a scroll disk can be arranged in the compression chamber. The heat dissipation structure includes a controller assembly and an air intake chamber 1. The controller assembly includes a controller housing 21. The controller housing 21 can also act as the end cover of the motor in the compressor, making the compressor with the controller housing 21 of the present utility model have a higher integration degree. The controller housing 21 is provided with a controller cavity 22. The air intake chamber 1 is located on the side of the controller housing 21 away from the controller cavity 22. A control component is arranged in the controller cavity 22. The control component includes controller electronic components for controlling the actions of various components of the compressor. By providing the controller cavity 22, the control component and other components can be separately spaced apart, facilitating sealing treatment and dust and water prevention.

[0027] As Figures 1-3As shown, the outer wall of the controller housing 21 facing the intake chamber 1 is the mounting surface, and an aluminum heat exchange component is provided on the mounting surface. By directly providing the heat exchange component on the controller housing 21, the need for an additional heat dissipation device is reduced, thus saving space, making the entire compressor more compact, simplifying the assembly steps, and improving production efficiency. The heat exchange component includes a first heat exchange portion and a second heat exchange portion. The height of the second heat exchange portion in the direction perpendicular to the mounting surface is lower than the height of the first heat exchange portion. The first heat exchange portion has a first heat exchange channel 5. A bearing mounting portion 4 protruding from the mounting surface is provided at the center position of the mounting surface. A number of first arc portions 3 protruding from the mounting surface are provided on the mounting surface. The center of the first arc portion 3 is concentric with the bearing mounting portion 4. The first heat exchange channel 5 is formed between adjacent first arc portions 3, between the first arc portion 3 and the bearing mounting portion 4, or between the first arc portion 3 and the outer wall of the intake chamber 1. The second heat exchange portion has a second heat exchange channel 8. An installation groove 6 recessed into the mounting surface is provided on the mounting surface. A second arc portion 7 protruding from the bottom of the installation groove 6 is provided in the installation groove 6. The second heat exchange channel 8 is formed between adjacent second arc portions 7, between the second arc portion 7 and the bearing mounting portion 4, or between the second arc portion 7 and the outer wall of the intake chamber 1. A reinforcing rib 9 is provided between two adjacent second arc portions 7. One end of the reinforcing rib 9 is connected to the second arc portion 7, and the other end of the reinforcing rib 9 is connected to the second arc portion 7, the bearing mounting portion 4, or the outer wall of the intake chamber 1. The height of the reinforcing rib 9 is lower than the height of the second arc portion 7. The reinforcing rib 9 extends substantially along the radial direction of the second arc portion 7. By adding the reinforcing rib 9, not only the overall structural strength of the heat exchange component is enhanced, compensating for the strength loss caused by the depression of the second heat exchange portion and preventing the housing from being damaged under the impact of the intake pressure, but also the residence time of the heat conduction medium and the heat dissipation area are increased, further enhancing the heat dissipation performance. The improved heat dissipation effect can prevent the control component from overheating, ensure the stable operation of the compressor, and extend the service life.

[0028] As Figures 2-3 shown, when the compressor is in the working state, the heat conduction medium entering the intake chamber 1 flows in from the intake port and flows through the second heat exchange portion and the first heat exchange portion in sequence. The heat exchange component and the intake port can be configured into other suitable height relationships according to the actual situation. An intake port is provided on one side of the second heat exchange portion and the intake port is inclined towards the installation groove 6. The intake port is located on the side of the intake chamber 1 and is inclined towards the installation groove 6, which is beneficial to guiding the cold air directly to the second heat exchange portion and further improving the cooling effect.

[0029] As Figures 1-3As shown, the heat dissipation structure for the hybrid vehicle compressor maximizes the contact area with the controller base plate through the configuration of the first heat exchange part and the second heat exchange part, thereby accelerating the heat transfer and dissipation, effectively preventing the overheating problem of the controller under high-load working conditions. Secondly, the low-position design and thin-wall structure of the second heat exchange part shorten the heat transfer path, optimize the air flow route, enable the heat-conducting medium to more effectively absorb and carry away the generated heat. The good heat dissipation effect can reduce energy loss, improve the overall energy efficiency of the compressor, contribute to reducing the energy consumption of the hybrid vehicle, not only improve the operating efficiency and system stability of the compressor, but also reduce the maintenance cost and failure rate caused by overheating. This heat dissipation structure provides an efficient, reliable and economical heat dissipation path for the hybrid vehicle compressor, ensuring the stability and safety of the vehicle during operation, and at the same time facilitating the stable operation and maintenance of the compressor.
