Extrusion process liquid cold plate
The liquid cooling plate of the extrusion process is used for high-power module batteries or power batteries. The efficiency of the liquid cooled plate is very high, and the cost is low. The length of the liquid cooled plate can be made about 2500mm
What is a die casting heat sink?
The die casting heat sink is an advanced and efficient heat dissipation solution. By using the die casting process, ADC12 can be used as the main raw material to shape a complex and exquisite heat sink structure. The core of this process is to inject molten metal into high-precision molds, rapidly cool and solidify under high pressure, forming a sturdy and integrated product.This type of heat sink has excellent thermal conductivity, effectively transferring the heat generated by the equipment to the surface of the heat sink, thereby achieving rapid heat dissipation.
At the same time, the die-casting process makes the product highly dense and precise, ensuring the stability and durability of the heat sink.Its precision casting not only ensures the quality of the product, but also makes the appearance design of the heat sink more fashionable. The lightweight design not only facilitates the installation process, but also reduces the overall weight of the equipment and improves its portability.Overall, the die casting process heat sink has become an ideal heat dissipation solution in various application scenarios due to its advanced manufacturing technology.
What are characteristics of extrusion liquid cold plate?
1. The material of cold plate is generally 6063 or 6061;
2, The heat sink surface can be sprayed with oil or powder, anodized;
3, Product processing time is relatively low, high production efficiency, low unit price;
4, Generally speaking, the length, width and height of the products are 2500X800X7.5-15mm we can make.
5,Our usual process of making this product is to get the customer’s drawing, we will do the DFM feedback, and then make the sample. After the sample is finally confirmed, we will mass produce;
6,Our general sample production cycle is 3 weeks, the production cycle of mass production is 4 weeks
Extrusion liquid cold plate is used in Laser equipment cooling solutions
The liquid cooling plate of the extrusion process can also be used for heat dissipation of laser modules. Generally, the heat generated by the laser module is very large. Due to the high efficiency of optical communication, each pump source will have a large amount of heat. The liquid cooling plate of the extrusion process can be used for heat conversion. Generally speaking, the section of the liquid cooling plate of this extrusion process can reach a width of about 600mm, and the middle flow channel can be made of 4 channels or 6 channels, This can form series or parallel flow channels for the exchange of liquid and heat. Of course, it is also possible to create microchannel features, as this process can save processing costs. It is a highly efficient heat dissipation method that we often recommend to our customers.
The extrusion liquid cold plate Inlet and outlet making technology .
The inlet and outlet of this liquid cooled plate usually need to be sealed off by welding process to form a closed loop.Friction stir welding process is one of them, which involves placing two aluminum blocks in the two cross-sections of the profile, and then welding the aluminum blocks and the profile together using the FSW process,Of course, the characteristic of this process is that it needs to be placed horizontally and requires a deeper welding depth, such as 10-15mm.
Argon fluorine welding is another process, which usually uses high current to melt the welding rod and leave fish scale like welding points on the cross-section of the profile. This process usually requires an automatic welding machine to complete the welding. Of course, the risk of this process is that sand holes are prone to occur, which poses a risk of leakage. Therefore, the leakage testing stage after welding is very important
How to test and control the quality of the extrusion liquid cold
The Processing and testing of liquid cooled plates.Usually, the external dimensions are processed according to the customer’s drawings, and the marked tolerances must comply with the requirements of the drawings. The unmarked tolerances are generally GB/T-1804-m. For the flow channel of the liquid cooled plate, the customer usually only provides an approximate size, or provides the heat source and position of the heating power, which requires detailed design.Generally speaking, the liquid in the flow channel is 50% distilled water and 50% ethylene glycol. The inlet water temperature of the chiller is generally controlled at around 20-25 degrees, with a flow rate of 8-15 liters per minute and a flow resistance of less than 350mbar. Therefore, the surface temperature of the cold plate tested does not exceed 45 degrees.
After the initial processing and welding of the liquid cooling plate, it is necessary to clean the surface and interior with deionized water with a conductivity of less than 3uS/cm. During testing, maintain the pressure at 1Mpa for 5 minutes without any water leakage.After the test is completed, bake the internal flow channel dry. No water droplets remain inside the channel. To ensure that no debris enters the channel, it is necessary to block the inlet and outlet of the channel with rubber plugs. This way, when shipped to the customer, it can be removed to ensure that the channel is clean and dust-free.
