Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted integrated transformer technology, specifically a heat dissipation new energy vehicle-mounted integrated transformer. Background Technology

[0002] An integrated vehicle transformer is a vehicle power device that integrates the core functions of a transformer with auxiliary circuits for protection and control. Its core function is to accurately convert the voltage of the vehicle power supply (such as a 12V / 24V low-voltage battery) into the specific voltage required by the vehicle electronic equipment (such as navigation, radar, and in-vehicle entertainment systems). At the same time, through integrated design, it can reduce size and weight, adapt to the limited space inside the car, and improve environmental resistance such as vibration resistance and high temperature resistance, ensuring stable power supply to the vehicle circuit under complex driving conditions.

[0003] The existing Chinese patent publication number CN220422214U, entitled "A Heat-Dissipating Integrated Transformer for New Energy Vehicles," explicitly states in its abstract that "This utility model relates to the technical field of heat-dissipating integrated transformers for new energy vehicles, and discloses a heat-dissipating integrated transformer for new energy vehicles, comprising a main body, a core body, and an auxiliary body. The core body is located inside the main body, and the auxiliary body is located at the outer end of the core body. The main body includes a transformer body, a first socket, and a USB port. The first socket is fixedly installed at the outer end of the transformer body, and the USB port is fixedly installed at the right end of the first socket. The main body also includes a power button, a switch button, a second socket, a base, and a handle. This heat-dissipating integrated transformer for new energy vehicles, by adding a base to the main body, can prevent the transformer from contacting the ground. Simultaneously, the base can increase stability and support, distribute weight, reduce the impact of ground moisture on the transformer, and extend the transformer's service life, effectively improving the practicality and convenience of the heat-dissipating integrated transformer for new energy vehicles."

[0004] However, in this technology, the existing transformers rely solely on internal heat sinks for heat dissipation. However, the transformer casing is relatively enclosed and cannot achieve good heat dissipation. With long-term use, internal heat is prone to accumulate, which may affect the working stability of the transformer and even shorten the service life of core components. It is difficult to meet the continuous and efficient heat dissipation requirements in vehicle scenarios. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation integrated transformer for new energy vehicles, in order to solve the problem mentioned in the background art of failing to achieve good heat dissipation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A heat dissipation integrated transformer for new energy vehicles includes a transformer body, a transformer shell on the transformer body, and a heat dissipation component on the top of the transformer shell. The heat dissipation assembly includes a slide groove, a sliding plate is slidably disposed inside the slide groove, an air inlet is disposed at the front bottom of the slide groove, and a fan is disposed inside the transformer housing.

[0007] In a preferred embodiment of this utility model, air outlet slots are provided on the lower sides of both sides of the transformer housing, and the air outlet slots penetrate the inner and outer sides of the transformer housing.

[0008] In a preferred embodiment of this utility model, a first dustproof net is provided inside the air outlet slot, and a second dustproof net is provided inside the air inlet.

[0009] In a preferred embodiment of this utility model, the air inlet penetrates the top of the transformer housing, and a baffle is provided behind the top of the slide groove.

[0010] In a preferred embodiment of this utility model, a first motor is provided at the bottom of the air inlet, and the bottom output end of the first motor is connected to a fan.

[0011] In a preferred embodiment of this utility model, a second motor is provided at the bottom rear of the air inlet, and a gear is provided on the output end of the second motor.

[0012] In a preferred embodiment of this utility model, a rack is provided at the bottom of the sliding plate, and the gear meshes with the rack.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: This utility model features a sliding plate that covers the air inlet when the fan is not in use and moves backward to open the air inlet when in use. Combined with a second dust filter, it effectively blocks dust from the vehicle environment. Simultaneously, the active airflow from the fan and the exhaust duct create an airflow channel, solving the problem of poor heat dissipation in existing transformers that rely solely on internal radiators and have enclosed casings. The active cooling structure significantly improves heat dissipation efficiency, effectively preventing internal heat buildup, ensuring the transformer's operational stability, extending the lifespan of core components, and meeting the continuous and efficient heat dissipation requirements of vehicle environments. Furthermore, the sliding plate design further reduces dust accumulation on the dust filter, lowering the frequency of cleaning. The overall structure does not alter the original transformer's core structure, offering strong compatibility and adaptability to the complex vehicle environment.

[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses a heat dissipation integrated transformer for new energy vehicles, including a transformer body 1. The transformer body 1 directly adopts the transformer in the background technology patent. The transformer body 1 includes a transformer shell 11, which is the protective shell of the transformer. It can be made of ABS engineering plastic, which has good impact resistance and high temperature resistance and is suitable for the complex environment of the vehicle. This patent installs corresponding structures on the sides and top of the transformer in the background technology patent where no structure is set, without affecting the original structure of the transformer.

[0020] A heat dissipation assembly is provided on the top of the transformer housing 11. The heat dissipation assembly includes a slide 2, which is located on the top of the transformer housing 11. A sliding plate 3 is slidably disposed inside the slide 2. The sliding plate 3 is made of ABS engineering plastic, which is the same material as the transformer housing 11. It has good structural strength and wear resistance, and can fit tightly against the inner wall of the slide 2. When the fan 24 is not in use, it can completely cover the air inlet 21, preventing dust from directly contacting the dustproof net.

[0021] An air inlet 21 is provided at the front bottom of the slide 2, and the air inlet 21 penetrates the top of the transformer housing 11. A second dustproof net 22 is installed inside the air inlet 21. The second dustproof net 22 is made of stainless steel wire with a mesh size of 80 mesh, which can effectively block dust and lint in the vehicle environment from entering the equipment and has good air permeability without affecting the air intake efficiency. A baffle 31 is provided at the rear top of the slide 2. The baffle 31 is an integral structure with the transformer housing 11 and is also made of ABS engineering plastic. It plays a limiting role to prevent the sliding plate 3 from moving too far backward and dislodging from the slide 2 when the fan 24 is used, and also has a blocking effect.

[0022] A fan 24 is installed inside the transformer housing 11. The fan 24 is a DC brushless fan, model 4010, which features low power consumption and high air speed, and is suitable for the power supply requirements of vehicle power supply. It can quickly promote internal air circulation. A first motor 23 is installed at the bottom of the air inlet 21. The first motor 23 is a micro DC motor, model 30BYJ46. The first motor 23 is fixed to the mounting base at the bottom of the air inlet 21 by bolts. The bottom output end of the first motor 23 is fixedly connected to the fan 24 by a coupling to ensure stable power transmission and drive the fan 24 to rotate at high speed.

[0023] A second motor 33 is located at the bottom rear of the air inlet 21. The second motor 33 is also a micro DC motor, model 28BYJ48. The second motor 33 is fixed to the mounting bracket inside the transformer housing 11 by screws. A gear 34 is fixedly installed on the output end of the second motor 33. The gear 34 is made of engineering plastic and has the characteristics of being lightweight and wear-resistant. A rack 32 is located at the bottom of the sliding plate 3. The rack 32 is fixedly connected to the sliding plate 3 by adhesive. The rack 32 and the gear 34 mesh with each other. The rotation of the gear 34 drives the rack 32 to move, thereby realizing that the sliding plate 3 moves backward inside the slide groove 2 when the fan 24 is in use and returns to its original position when not in use.

[0024] Air outlet slots 12 are provided on both sides of the lower part of the transformer shell 11. The air outlet slots 12 penetrate the inner and outer sides of the transformer shell 11. A first dustproof net 13 is installed inside the air outlet slot 12. The first dustproof net 13 and the second dustproof net 22 are made of the same material and have the same mesh size. They are used to block dust. At the same time, the airflow generated by the operation of the fan 24 will flow from the inside of the transformer shell 11 to the air outlet slot 12. During the process, positive wind pressure can be formed on the inner side of the first dustproof net 13, reducing the external dust adhering to the outer side of the dustproof net, and even blowing away the slightly accumulated dust, reducing the risk of dustproof net blockage. A controller is also provided on one side of the bottom rear of the air inlet 21. The controller is a single-chip microcontroller, model STM32F103. The controller is electrically connected to the first motor 23 and the second motor 33 through wires to control the start, stop and speed adjustment of the first motor 23 and the second motor 33. The controller is also electrically connected to the power supply circuit of the transformer body 1 to obtain working power.

[0025] The working principle of this utility model is as follows: The controller receives the working status signal of the transformer body 1. When the transformer body 1 needs to start the fan 24 for heat dissipation, the controller first starts the second motor 33. The second motor 33 drives the gear 34 to rotate. The gear 34 meshes with the rack 32 to drive the sliding plate 3 to move backward in the slide groove 2 until it stops contacting the baffle 31, fully opening the air inlet 21. Then the controller starts the first motor 23. The first motor 23 drives the fan 24 to rotate, drawing external cold air into the transformer shell 11 through the air inlet 21. The cold air flows through the heat-generating components of the transformer body 1, carrying away the heat, and then is discharged through the air outlet slots 12 on both sides of the transformer shell 11, forming a complete heat dissipation airflow channel. When the transformer body 1 does not need to use the fan 24, the controller first controls the first motor 23 to stop running, and then controls the second motor 33 to rotate in the opposite direction, driving the sliding plate 3 to reset forward in the slide groove 2, completely covering the air inlet 21 and preventing dust from directly contacting the second dustproof net 22.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
