Description

Technical Field

[0001] This utility model belongs to the field of thermal management technology, and specifically discloses a welded and spliced ​​wide hollow cooling plate. Background Technology

[0002] With the rapid development of technology, the power density of electronic devices, communication facilities, and various industrial equipment is constantly increasing, and heat dissipation has become a key factor restricting their performance and stability. Against this backdrop, cooling plates, as a highly efficient thermal management component, are experiencing a continuous growth in market demand.

[0003] Currently, commonly used liquid cooling plates on the market are mainly made of metals such as stainless steel, aluminum alloy, titanium alloy, and copper. These materials are widely used in traditional cooling plate manufacturing due to their excellent thermal conductivity and mechanical strength. However, most existing cooling plates use processes such as embedded pipes and die-casting-welding to form liquid flow channels to achieve heat dissipation. While these traditional processes can meet basic heat dissipation requirements to some extent, they also have many shortcomings. First, from a structural design perspective, existing cooling plates have relatively simple structures and low space utilization. Within limited installation space, traditional cooling plates often cannot fully utilize the space to increase the heat dissipation area, making it difficult to further improve heat dissipation efficiency. At the same time, these cooling plates are mostly made of metal, making them heavy and lacking lightweight design concepts, which becomes a significant drawback in weight-sensitive applications such as electric vehicles. Second, the heat dissipation effect of existing cooling plates is relatively poor. Their heat dissipation area and flow channel layout are often unreasonable, easily leading to increased thermal resistance and uneven heat dissipation during liquid flow, thus reducing heat dissipation efficiency. When high-power equipment is running, this low heat dissipation efficiency may cause the equipment to overheat, thereby affecting its performance and service life. Furthermore, the manufacturing process of existing cooling plates is relatively complex. Traditional processes such as die casting and welding are not only inefficient but also relatively expensive. Due to the complexity of the process, large-scale production is difficult, making it hard to meet the growing market demand for cooling plates. In addition, existing cooling plates often experience problems such as water leakage during use, which not only affects the normal use of the cooling plates but may also damage equipment. Poor sealing and low strength limit the service life of the cooling plates, and their reliability needs further improvement.

[0004] In summary, existing cooling plates have many shortcomings in terms of structural design, heat dissipation performance, manufacturing process, and quality reliability. To address these issues, this study researches and designs a novel welded and spliced ​​wide-width hollow cooling plate to overcome the deficiencies of existing cooling plates and meet the stringent heat dissipation requirements of modern high-power equipment, which is of significant practical importance.

[0037] This embodiment provides a welded and spliced ​​wide hollow cooling plate, such as... Figure 1 and Figure 2 As shown, it includes a main profile 1, a first plug 2, a second plug 3, an inlet / outlet 4, and a plug core 5, as follows. Figure 3 and Figure 4 The main profile 1 has multiple axially arranged baffles 1-1 inside, and cooling channels 1-2 are formed between adjacent baffles 1-1. A first plug 2 is set at one end of the main profile 1 and is plugged into the main profile 1 through a first sealing structure. A second plug 3 is set at the other end of the main profile 1 and is plugged into the main profile 1 through a second sealing structure. The first sealing structure and the second sealing structure alternately seal the odd-numbered and even-numbered baffles 1-1, so that the coolant forms a meandering path in the channel. The inlet and outlet 4 are set at the end of the cooling channel 1-2 for the input and output of coolant. The insert 5 is set in the second plug 3 for connection with external connectors.

[0038] As a preferred embodiment, specifically, the main profile 1 is an integrally extruded aluminum alloy profile, and the width of the main profile 1 is not less than 600mm. More specifically, the material of the main profile 1 is 6061 aluminum alloy. The 600mm multi-cavity wide cross-section design of the main profile 1 in this embodiment not only meets the functional design requirements of the cooling channels 1-2, but also reduces the number of weld beads through integral extrusion molding, improving the overall strength, aesthetics, and sealing performance of the main profile 1.

More specifically, the width of each first protrusion 2-1 can be different and can be set according to the specific situation of the cooling channel. The first plug-in plug 2 is made of high-performance 6061 aluminum alloy and multiple first protrusions 2-1 are formed by CNC machining, i.e., a stepped sealing structure.

The end of each second protrusion 3-1 abuts against the end of an even-numbered partition 1-1, and the left and right sides of each second protrusion 3-1 abut against the sidewalls of the adjacent partition 1-1. More specifically, the width of each second protrusion 3-1 can be different and can be set according to the specific situation of the cooling channel. The left and right sides of the second protrusion 3-1 located in the middle position do not need to abut against the sidewalls of the adjacent partition 1-1. The second plug 3 is made of high-performance 6061 aluminum alloy and is formed into a sealing structure by CNC machining. The stepped sealing structure can be seamlessly plugged into the main profile 1, improving the overall assembly efficiency and enhancing the overall strength and sealing performance. The middle position of the second plug 3 is machined by CNC machining, and its shape and position are precisely for tight connection with external equipment.

[0041] In a preferred embodiment, the inlet / outlet 4 is equipped with an L-shaped pipe that connects to the cooling channel 1-2 for connecting to an external water nozzle. The inlet / outlet 4 is formed by CNC machining. More specifically, the inlet / outlet 4 is made of high-performance 6061 aluminum alloy and is formed into a stepped circular hole by CNC machining. This facilitates a tight fit and connection with the water nozzle and connects to the hole in the main profile 1. The hole is positioned precisely at the water channel location, serving as a receiving element and allowing for water flow through the inlet and outlet.

[0042] In a preferred embodiment, the second plug 3 has a slot, and the insert 5 is fixed in the slot by plugging. More specifically, the insert 5 is made of high-performance 6061 aluminum alloy and is CNC machined into the second plug 3, mainly for connecting with external connectors, specifically for connecting with an external ground wire. The main profile 1 also has a temperature measuring hole for measuring the internal temperature of the main profile 1.

[0043] In manufacturing this welded and spliced ​​wide hollow cooling plate, the first plug 2 and the second plug 3 are respectively inserted into the main profile 1. They are welded together around the top and bottom circumference using friction stir welding, with a penetration depth of approximately 4mm, ensuring full penetration at the connection points between the main profile 1 and the first and second plugs 2 and 3, guaranteeing the overall sealing and strength of the cooling plate structure. The inlet and outlet ports 4 are inserted into the corresponding slots on the main profile 1 and then sealed and fixed using arc welding, achieving water passage. The insert 5 is inserted into the slot of the second plug 3, achieving a tight connection with external connectors. Finally, temperature measurement holes are opened on both sides of the assembled cooling plate for measuring the internal temperature for control and monitoring. This welded and spliced ​​wide hollow cooling plate is an innovative structure designed specifically for high-performance heat dissipation needs. It is made of 6-series aluminum alloy, combining excellent thermal conductivity with lightweight advantages. The carefully designed flow channel structure inside the cooling plate ensures smooth coolant flow, achieving efficient heat exchange while also possessing excellent corrosion resistance and sealing performance.
