We dedicated to this project, be responsible for the whole process, Participate in customer's preliminary design cooperation, research, evaluation, development, verification ,production--- To achieve worry free cooling for customers and pave the way for the reliability of their products.

 

Case

ITX BOX COOLING SOLUTION

Rated products

DC blower fans + computer cooler

Customer industry

ITX Computer

Customer demand

The customer wants to develop an ITX computer with a CPU power of 65W,let us make the parts of cooling solution

Customer intention

Relieve the heat generated by the entire CPU, ensuring the safety and stability of his product

Solution

We recommend using a combination of heat pipes+fins(computer cooler), and blower cooling fans to dissipate heat according to customer requirements

Project Plan/Process

Product thermal simulation, optimization and modification, Mold development, Sample testing, Mass production

Project results

Solved the problem of high CPU temperature caused by high MOS temperature through segmented heat dissipation,get high evaluate from customer and get their series products cooling project.

 

Through thermal simulation to check if the first choose products works perfectly.

From thermal simulation we found out Overall high risk:the core risk is that the cooling module cannot handle the current heating power. Insufficient air volume in the system poses a risk of SOC temperature. So the current cooling module is unable to solve the core heat generation rate of 70W.

 

 

Based on the result of thermal simulation we suggested some modification advise

 

  1. Adjust the gap between the small blower fans and the cooler fins, and seal the gap with acetic acid adhesive tape
  2. Add thermal conductive silicone pad between copper tube and MOS
  3. Increase the speed of the blower and increase the air volume
  4. The opening rate of the air outlet increase to 70%....etc

Final test records is perfect after adjustment,and final installation photo;
