Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat sink technology, and in particular to an inverter heat sink. Background Technology
[0002] Inverters generate significant heat during operation, especially under high load or high-temperature conditions. Heat dissipation has become a critical factor limiting inverter performance improvement and stable operation. Traditional heat sinks typically use a single aluminum plate, which has limited heat dissipation capacity and cannot meet the ever-increasing cooling demands. Redesigning the heat sink to improve its cooling capacity involves not only rearranging the power boards and heat sink but also redesigning the existing mounting holes on the heat sink. This design change process is complex, time-consuming, and costly, making it highly uneconomical for minor performance improvements.
[0003] Furthermore, while a completely new design could be used to significantly improve inverter performance, for cases requiring only minor improvements in heat dissipation and load capacity, the time and cost of a new design far exceed expectations. Therefore, there is an urgent need for a technical solution that can address insufficient heat dissipation while minimizing the impact of design changes and reducing costs. Based on this, an inverter heatsink has been developed that rapidly improves heat dissipation capacity by partially modifying the original heatsink and using low-cost extrusion molds. This satisfies the need for optimized heat dissipation performance at minimal cost without affecting installation and use. Utility Model Content

[0005] Preferably, the heat sink body has openings at both ends, and cover plates are provided at the positions of the two openings, and the cover plates are tightly fixed to the heat sink body.
[0006] Preferably, the top and bottom ends of the first partition are tightly fitted to the inner wall of the heat sink body, and the top and bottom ends of the second partition are tightly fitted to the inner wall of the heat sink body, and the first partition, the second partition and the heat sink body are integrally formed.

[0009] Beneficial Effects: Compared with existing technologies, this invention addresses the shortcomings of traditional solid aluminum heat sinks, such as insufficient heat dissipation capacity and high costs associated with entirely new designs. This patent utilizes a low-cost extrusion mold to partially modify the original heat sink, creating a structure with an internal hollow core and alternating partitions. The coolant flows in a meandering pattern guided by the partitions, significantly increasing the heat exchange area and time compared to traditional heat sinks. This results in a substantial improvement in heat dissipation efficiency at a lower cost, effectively meeting the heat dissipation requirements of inverters under high load and high temperature environments. It also solves the problem of layout adjustments required for redesigning heat sinks with multiple power board mounting holes already present. This patent optimizes heat dissipation performance through partial modification without altering the heat sink's mounting dimensions or affecting the installation and use of the power boards. It avoids the complex processes and high costs associated with a complete redesign of the power boards and heat sinks, while shortening the development cycle. In scenarios requiring small-scale performance improvements, it demonstrates significant time and cost advantages. Attached Figure Description

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0016] Example
[0017] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, an inverter heat sink includes a heat sink body 1, which is disposed at the bottom of an inverter 2. The heat sink body 1 has a hollow internal structure and is provided with multiple partitions 3 and 4, which are alternately distributed. There is a gap between adjacent partitions 3 and 4. One end of the heat sink body 1 is provided with a water inlet 5, and the other end of the heat sink body 1 away from the water inlet 5 is provided with a water outlet 6. The lower end of each partition 3 is provided with a through hole 9, and the upper end of each partition 4 is provided with a through hole 9.
[0018] Both ends of the heat sink body 1 are provided with openings, and cover plates 7 are provided at the positions of the two openings. The cover plates 7 are tightly fixed to the heat sink body 1.
[0019] The top and bottom of the partition 3 are tightly fitted to the inner wall of the heat sink body 1, and the top and bottom of the partition 4 are tightly fitted to the inner wall of the heat sink body 1. The partition 3, partition 4 and the heat sink body 1 are integrally formed.
[0020] The heat sink body 1 is provided with a plurality of mounting holes 8, and the mounting holes 8 are vertically opened on the partition 3.
[0021] The water inlet 5 is connected to the interior of the heat sink body 1, and the water inlet is located at the beginning of the area where partition 3 and partition 4 are alternately distributed. The water outlet 6 is connected to the interior of the heat sink body 1, and the water outlet 6 is located at the end of the area where partition 3 and partition 4 are alternately distributed.
[0022] Working Principle: Coolant is introduced into the heat sink body through the inlet. Due to the alternating distribution of baffles one and two, and the through-holes at the lower end of baffle one and the upper end of baffle two, the coolant flows in a meandering pattern within the gaps between adjacent baffles one and two, gradually flowing from the inlet to the outlet, finally exiting from the outlet, forming a complete circulation path. The heat sink body is located at the bottom of the inverter, and the heat generated during inverter operation is conducted to the heat sink body. When the coolant flows within the heat sink body, its temperature is lower than that of the heat sink body. According to the principle of heat transfer, heat is transferred from the heat sink body to the coolant, thereby lowering the temperature of the heat sink body and achieving the purpose of cooling the inverter.
[0023] In the aforementioned process, this utility model addresses the issues of insufficient heat dissipation capacity and high cost of redesigning traditional solid aluminum heat sinks. This patent utilizes a low-cost extrusion mold to partially modify the original heat sink, creating a structure with an internal hollow core and alternating partitions. The coolant flows in a meandering pattern guided by the partitions, significantly increasing the heat exchange area and time compared to traditional heat sinks. This results in a significant improvement in heat dissipation efficiency at a lower cost, effectively meeting the heat dissipation requirements of inverters under high load and high temperature environments. It also solves the problem of layout adjustments required for redesigning heat sinks with multiple power board mounting holes already present. This patent optimizes heat dissipation performance through partial modification without changing the heat sink's mounting dimensions or affecting the installation and use of the power boards. It avoids the complex processes and high costs of completely redesigning the power boards and heat sinks, while shortening the development cycle. In scenarios requiring small-scale performance improvements, it demonstrates a strong time and cost advantage.
