Description

Technical Field

[0001] This utility model relates to the field of frequency converter technology, specifically to a high-sealing frequency converter heat dissipation structure. Background Technology

[0002] Inverters are widely used power electronic devices that play a crucial role in many fields such as industrial production, transportation, and smart homes. They generate a significant amount of heat during operation; if this heat is not dissipated effectively and promptly, the internal components will overheat, affecting the inverter's performance, reliability, and lifespan. In certain specialized applications, such as humid, dusty, or corrosive environments, the inverter's sealing performance is extremely critical to prevent external moisture, dust, and corrosive substances from entering and damaging the circuit components. However, conventional heat dissipation structures often struggle to achieve both high sealing performance and effective heat dissipation, thus limiting the inverter's stable operation in complex and harsh environments.

[0003] Existing inverter cooling methods, such as relying solely on the casing for heat dissipation, have low efficiency and cannot meet the cooling requirements of high-power inverters. While air cooling can improve efficiency, it suffers from inadequate sealing, making it vulnerable to harsh environmental factors. Some structures attempting to balance sealing and heat dissipation suffer from poorly designed heat dissipation channels, leading to poor airflow and significantly reduced cooling performance, or complex and costly sealing structures, hindering large-scale application. Therefore, developing an inverter cooling structure that meets both high sealing requirements and efficient heat dissipation performance is of significant practical importance. Utility Model Content

This solves the problems of existing inverter heat dissipation methods, such as relying solely on the casing for heat dissipation, which has low efficiency and cannot meet the heat dissipation requirements of high-power inverters; and while air cooling can improve efficiency, it suffers from insufficient sealing, making it difficult to resist the intrusion of harsh external environmental factors. Some structures attempting to balance sealing and heat dissipation suffer from inadequate heat dissipation channel design, leading to poor airflow and significantly reduced heat dissipation, or complex and costly sealing structures, hindering large-scale application.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing inverter heat dissipation structure, comprising a fan duct, an inverter body disposed at the bottom of the fan duct, the inverter body communicating with the fan duct, a first fan fixedly connected to the inside of the fan duct via a bracket, and three air ducts connected to the top of the fan duct, the end of each air duct away from the fan duct communicating with the inverter body, openings on both the front and back of the inverter body, a support frame fixedly connected to both the front and back of the inverter body, the support frame communicating with the openings, a filter screen disposed inside the support frame, an electric telescopic rod fixedly connected to both the front and back of the inverter body via a bracket, a baffle fixedly connected to the output end of the electric telescopic rod, and several heat dissipation fins fixedly connected to both the front and back of the inverter body.

[0012] 1. This utility model employs a cleverly constructed heat dissipation system that coordinates the operation of core components such as the air duct, air supply pipe, first fan, and heat dissipation fins.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, a high-sealing inverter heat dissipation structure includes a duct 1, an inverter body 2 at the bottom of the duct 1, the inverter body 2 being connected to the duct 1, a first fan being fixedly connected to the inside of the duct 1 via a bracket, and three air ducts 3 being connected to the top of the duct 1. The end of the air duct 3 away from the duct 1 is connected to the inverter body 2. The front and back of the inverter body 2 are provided with openings, and support frames 4 are fixedly connected to the front and back of the inverter body 2, with the support frames 4 being connected to the openings. A filter screen 5 is provided inside the support frames 4. Electric telescopic rods 6 are fixedly connected to the front and back of the inverter body 2 via brackets, and a baffle 7 is fixedly connected to the output end of the electric telescopic rods 6. Heat dissipation fins 13 are fixedly connected to the front and back of the inverter body 2, and the number of heat dissipation fins 13 is several.

[0021] refer to Figure 2 The top and bottom of the left side of the inverter body 2 are fixedly connected to the second fan 8.

[0022] As a technical optimization of this utility model, by setting the second fan 8, the air flow rate on the surface of the air duct 3 can be increased, thereby improving the heat dissipation speed of the airflow in the air duct 3, and thus indirectly dissipating heat from the electrical appliances in the inverter body 2.

[0023] refer to Figure 4 A heat-conducting strip 9 is fixedly connected inside the air duct 3. There are several heat-conducting strips 9, which are evenly distributed in a ring inside the air duct 3. The heat-conducting strips 9 are located on the left side of the second fan 8.

[0024] As a technical optimization of this utility model, by setting the heat-conducting strip 9, one end of the heat-conducting strip 9 extends into the interior of the air duct 3 and the other end extends into the exterior of the air duct 3. The heat-conducting strip 9 will not affect the normal air supply of the air duct 3. The heat-conducting strip 9 can increase the heat dissipation area of ​​the air duct 3, thereby further improving the heat dissipation speed of the air inside the air duct 3, and thus indirectly dissipating heat from the electrical appliances inside the inverter body 2.

[0025] refer to Figure 3 The internal threaded connection of the support frame 4 is provided with bolts 12, and there are several bolts 12. The surface of the bolts 12 is coated with anti-rust paint. The surface of the filter screen 5 is provided with a slot, and the bolts 12 are inserted into the slot.

[0026] As a technical optimization of this utility model, by setting the bolt 12 and the slot, the operator can disassemble the bolt 12, so that the bolt 12 is separated from the slot, thereby releasing the restriction on the filter screen 5. Then the operator moves the filter screen 5 to the side away from the inverter body 2, thereby disassembling the filter screen 5, which makes it easier for the operator to clean or replace the filter screen 5. The filter screen 5 includes a frame and a filter screen. The frame is square, and the slot is set on the surface of the frame.

[0027] refer to Figure 3 A sealing gasket 11 is fixedly connected to the surface of the baffle 7, and the sealing gasket 11 is attached to the support frame 4 and the filter screen 5 respectively.

[0028] As a technical optimization of this utility model, by setting the sealing gasket 11, the sealing between the baffle 7 and the filter screen 5 can be increased, thereby improving the sealing effect of the baffle 7 on the filter screen 5.

[0029] refer to Figure 1 A protective frame 10 is fixedly connected to the left side of the inverter body 2. There are several protective frames 10, which are evenly distributed on the left side of the inverter body 2.

[0030] As a technical optimization of this utility model, the protective frame 10 can prevent the air duct 3 or the second fan 8 from being damaged by impact to a certain extent. The top of the inverter body 2 is fixedly connected with a handle for carrying the inverter body 2. The inverter body 2 mentioned above is a common existing technology and is common knowledge known to those in the art. This application will not describe it in detail.

[0031] The working principle and usage process of this utility model are as follows: During use, the electrical appliances inside the inverter body 2 generate heat, which raises the temperature of the gas inside the inverter body 2 and consequently, the temperature of the inverter body 2's outer casing. The heat dissipation fins 13 increase the contact area between the inverter body 2's outer casing and the external air, thus providing the first stage of heat dissipation for the inverter body 2. The operator can activate the first fan to allow the hot air inside the inverter body 2 to enter the air duct 1 and then the air supply pipe 3. Then, the second fan 8 is activated to cool the air in the air supply pipe 3. The cooled air then flows back into the inverter body 2, further cooling the inverter body. The inverter body 2 performs a second stage of heat dissipation. With the above two heat dissipation methods, external air cannot enter the inverter body 2, thereby improving the sealing performance of the inverter body 2. It has a good heat dissipation performance in the humid rainy season. A temperature detector is installed inside the inverter body 2. When the temperature detector detects that the temperature inside the inverter body 2 is too high, the temperature detector controls the electric telescopic rod 6 to retract through the external control component, thereby driving the baffle 7 and the sealing gasket 11 to move upward. At this time, external air can enter the inverter body 2 through the filter screen 5, the support frame 4 and the opening, thereby increasing the air exchange speed inside the inverter body 2, and thus providing heat dissipation protection for the inverter body 2.
