Technical Field

[0001] This utility model relates to the field of die casting technology, specifically to adding a water-cooling heat dissipation structure to die castings. Background Technology

[0002] Die casting is a casting formed by rapidly injecting molten metal into a precision mold under high pressure and then cooling and solidifying it to form a complex shape. It is currently used in the encapsulation of core components of electronic equipment (such as server modules) or precision mechanical equipment. The die casting body is provided with a module heat absorption zone for temperature control of internal precision components.

[0003] Currently, the heat dissipation method for die-cast parts is usually to set multiple heat dissipation fins on the die-cast part body and use external fans or natural wind to dissipate heat from the die-cast part. However, with the miniaturization of electronic devices, the space for heat dissipation fins on die-cast parts is limited. When the spacing between adjacent heat dissipation fins is too small or too large, it will affect the heat dissipation effect on the die-cast part, thereby affecting the performance of precision components inside the die-cast part. Utility Model Content

By adding a water-cooling heat dissipation structure inside the die casting body, the cooling time of the die casting can be effectively shortened by using a water-cooling circulation method, thereby improving the heat dissipation efficiency of the die casting and solving the problems mentioned in the background art.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a water-cooled heat dissipation structure is added to a die-casting part, including a die-casting part body 1, a heat-absorbing area 6 is provided on the lower surface of the die-casting part body 1, and a water-cooled heat dissipation structure 2 for water-cooled circulation heat dissipation is provided on the die-casting part body 1.

[0024] The water-cooled heat dissipation structure 2 includes a water channel 21 formed on the upper surface of the die-cast body 1 and a cover plate 22 located on the water channel 21. The cover plate 22 is welded to the surface of the water channel 21 by friction welding. The water channel 21 is provided with a flow guiding structure for guiding water cooling and improving the strength of the die-cast body 1. The die-cast body 1 is provided with an inlet 5 and an outlet 3 communicating with the water channel 21. By friction welding the cover plate 22 to the die-cast body 1 on the surface of the water channel 21, no filler material is required, the welding time is short, the heat-affected zone is small, the structural strength is ensured, the bonding force between the cover plate 22 and the die-cast body 1 is effectively improved, the sealing performance between the cover plate 22 and the die-cast body 1 is improved, coolant leakage is prevented, and reliability is improved.

[0025] The water channel 21 includes a first flow channel 211 connected to the liquid inlet 5, an S-shaped flow channel 212 located in the heat absorption zone 6, and a second flow channel 213 connected to the liquid outlet 3. The shape of the cover plate 22 is matched with the shape of the water channel 21, so that the liquid in each flow channel can maintain the same temperature and flow rate, which increases the contact time between the coolant and the die casting, improves the heat exchange efficiency, and the flow channel partitioning makes the coolant evenly distributed, improves the uniformity of heat dissipation to the heat absorption zone 6 by each flow channel, and avoids local overheating.

[0026] The flow guiding mechanism includes a first flow guiding component 7 located in the first flow channel 211 and an S-shaped flow guiding component 8 located in the S-shaped flow channel 212, with a gap between the first flow guiding component 7 and the S-shaped flow guiding component 8. The first flow guiding component 7 and the S-shaped flow guiding component 8 guide the flow of coolant, prevent eddies and dead zones, ensure uniform fluid flow, and improve heat dissipation efficiency.

[0027] The first guide member 7 is composed of multiple straight plates parallel to the liquid flow direction. The multiple straight plates are equidistantly distributed inside the first flow channel 211, and the straight plates are integrally formed with the die-cast body 1. The upper end of the straight plate abuts against the cover plate 22, so that the coolant passes through the flow channel formed by the adjacent straight plates, ensuring that the fluid flows along a predetermined path. At the same time, the abutment between the straight plate and the cover plate 22 can increase the support force on the cover plate 22 and improve the overall strength of the die-cast part.

[0028] The S-shaped guide 8 is composed of multiple parallel S-plates whose shape matches the S-shaped flow channel 212. The lower ends of the multiple S-plates are integrally formed and connected to the bottom of the S-shaped flow channel 212, and the upper ends of the S-plates abut against the cover plate 22. The S-plate structure enhances the flow of coolant in the curved flow channel, reduces pressure loss, increases turbulence, and improves heat exchange efficiency. At the same time, the S-plates can also increase the support force on the cover plate 22, thereby ensuring the strength of the die-cast part itself.

[0029] The inlet 5 and outlet 3 are both located on the same side of the die-cast body 1. Mounting holes 4 are provided on the side wall of the die-cast body 1 located on the outer periphery of the outlet 3 and the inlet 5. The mounting holes 4 are distributed at equal angles on the outer periphery of the outlet 3 and the inlet 5, which facilitates the connection of external coolant supply equipment and coolant recovery equipment to the die-cast body 1 through flanges, thereby improving the ease of installation.

[0030] In use, the external coolant supply equipment is connected to the inlet 5 via a flange, and the coolant recovery equipment is connected to the outlet 3. The coolant recovered by the coolant recovery equipment is then supplied back to the coolant supply equipment, achieving coolant recycling. The coolant enters the first flow channel 211 from the inlet 5, is guided by the straight plate guide, and flows evenly to the S-shaped flow channel 212. The S-plate guide in the S-shaped flow channel 212 creates turbulence in the coolant, enhancing heat exchange with the surface of the die-cast part and effectively removing heat from the heat absorption zone 6. Subsequently, the coolant enters the second flow channel 213 and is finally discharged from the outlet 3. The guide ensures a stable fluid path and reduces pressure loss, while the friction-welded cover plate 22 ensures sealing and prevents leakage. The entire design improves heat dissipation efficiency by optimizing the flow channel shape and guide structure, ensuring stable operation of the die-cast part in a high-temperature environment.

[0031] It should be noted that both the coolant supply equipment and the coolant recovery equipment are commercially available and are not covered by this utility model. Therefore, they are not described in detail here. The coolant supply equipment is connected to a storage tank containing coolant via a pump. The coolant recovery equipment is used to collect, filter, and cool the coolant flowing out of the water channel 21.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
