Custom Cold Plate Design

liquid cooled cold plates offer superior cooling for high power electronic devices, and can be purchased as standard cold plates or can be custom designed. One custom cold plate is needed when there are some special shape or interface requirements or an extreme performance requirement. An extreme performance requirement occurs when the specified standard cold plate performance cannot be uniformly applied across the entire cold plate or the cost of a compliant cold plate would be too high. A thermal map, or the distribution of heat loads, may have one or some areas with high heat loads. If there are cold plate surface temperature uniformity requirements, special shape or interface deign requirements, or cost limitations that a standard cold plate design can not meet these requirement, then a custom cold plate is the liquid cool solutions. Understanding cold plate manufacturing technologies, thermal specifications, and the steps involved in the cold plate design process will help us to provide the design custom cold plate design so it provides the best value possible.

To obtain the best custom liquid cold plate design, Lori needs the participation of the design engineers at the beginning of the process. Although each custom cold plate is different, the fundamentals of the design are the same. We use advanced thermal analysis software to simulate your thermal loads, and then Our teams create a custom cold plate design that meets or exceeds your requirements, and is cost-effective and reliable.

Cold Plate Types and Technologies

Cold plate Performance requirements generally dictate choice of cold plate technology and design, and cold plate technology will affect cold plate cost. Generally speaking, the cost of cold plate will increase with improving performance. Cold plate main types include pressure pipe cold plate (also called hi-contact cold plate), gun-drilled cold plate, channeled cold plate, brazed cold plate, etc. The channel of cold plates can be cnc machined, extrusion, friction welding channel,

And the cold plate machining channel according to the different ways of welding is divided into vacuum brazing, friction stir welding and other processes. The fins in the channel can also be divided into many types according to the process, such as profile, skived fin, welding, and so on.

Pressure pipe cold plate

Pressure pipe cold plate have copper or stainless steel pipes pressed into a channeled aluminum extrusion, which include the hi-contact liquid cold plate. Custom pipe cold plates can be designed in virtually any shape or size and the fluid path can be custom designed for optimal thermal performance. Custom machined, extrusion, friction welding channels, coatings, drilling, and tapping may be incorporated as well.

Gun-drilled cold plate

Gun-drilled cold plate is fabricated by drilling a hole through an aluminum plate, and, when applicable, inserting and expanding copper or stainless steel pipe. The results in dual-sided cold plate that can be drilled or tapped. One additional benefit of gun-drilled cold plate is that they can have tighter tolerances than pressed pipe cold plate, specifically for the flatness requirements.

Channeled Cold Plate

Channeled cold plate is extrusion with multi-channels, machined channels, friction welding channels or other methods of forming channels. The extrusion can provide only straight channels, but machining, friction welding, and other new metal cutting methods can provide a much more efficient shape. Channeled cold plate can be manufactured in any length, and assembled in a ladder configuration or integrated into a base cold plate for large area cooling. The channeled Cold Plate can also be conversion coated or anodized for added protection. Several patterns for the different ranges of required impedance, pressure drop, and the flow have been developed.

Brazed Cold Plate

Brazed Cold Plate consist of two plates metallurgically bonded together with internal fin. it can be vacuum brazed with a variety of fin densities and shapes (plain, louvered, lanced-offset, etc.). This internal fin, such as the fins within the braze cold plate, adds the heat transfer surface and increases turbulence to the flow. Brazed cold plate generally have the most flexibility with their design. Brazed cold plate material Options: AL6061, AL6063, C101, C102, C110, C145.

Brazed cold plate Internal Fin Structure: Machined, Folded Fin, Stamped Fin.

Defining the Heat Map

Cold plates have several possible thermal solutions, the first step in custom cold plate design is to define the thermal map in detail. To create a heat map, our engineer needs the dimensions, locations, and heat loads of the components to be cooled. Maximum allowable cold plate surface temperature; Coolant composition, flow rate and inlet temperature; and the available the pressure drop are need as well. In addition, the heat flux (including heat diffusion, if necessary) for each component must be calculated.

Reducing Cold Plate Manufacturing Cost

In Generally, the more flexible the design is, the easier the cold plate will be to engineer and the more savings you'll realize. By working closely with the printed circuit board designer or electrical engineer, Our thermal engineer can provide input on the spacing and positioning of components to ensure they are designed with the electrical engineer as well as thermal requirements in mind. The may significantly simplify the liquid cold plate design and reduce cost. ( For more information on the cost of cold plate, please click on "Cold Plate Manufacturing Cost ".)

Water cold plate customization process is as follows

1. Understand liquid cold plate processing requirements

Accept the customer's task, Lori R & D design team will fully communicate with the customer. Detailed understanding of product heating chip specifications, heat dissipation power, working environment and other detailed data, and combined with customer needs to give the most cost-effective water cold plate solution.

2. Design and simulation of liquid cold plate.

Lori’s R & D team according to customer needs to design water cold plate. And with the customer to determine the water cold plate details. The engineer simulates the structural design of the product (mainly cold head), determines the material, surface treatment and manufacturing process of the water cold plate through thermal simulation, ensures the water cold plate installation, maintenance, versatility and environmental protection requirements, and formulates the corresponding inspection standards.

3. Provide water cold plate prototype, production test.

After the design of water cold plate is passed, make prototype production, general plan and enter test link. Keep close communication with the customer during the test process, and adjust and modify according to the actual situation until meeting the customer's requirements

4. Water cold plate installation, acceptance.

After the test is passed, it will be delivered to the customer and installed and tested by our customer, and accepted by our customer.

5. After sale service of water cold plate
