The Liquid Cooling Plate Introduction

Water cooling is a method of heat removal

from components in industrial equipment with the help

of cooling plates. These cooling plates are used in

naval applications, heavy electronic industries and

inverters. Generally electronic equipment having

IGBT’s and each IGBT dissipates 791W of power. The

safe limit for industrial equipment, the temperature

should not exceed 900C.The objective of this work is

comparing 3 different profiles of cooling plates to

maintain the equipment in safe temperature condition.

In this study, evaluation of3 different types of cooling

plates through CFD analysis by fixing the diameters of

inlet and outlet portions are kept constant. The design

of cooling plate placed upon 8 IGBT’s and the analysis

of flow by using solid works flow simulation software.

Comparing three different cooling plates i.e. the Form

tube, Machined channel and Deep drilled cold plate

and Optimization is done by considering weight of the

cold plate and better temperature distribution.

1. INTRODUCTION

In heavy electronic equipped industries, high

temperatures are attained in working conditions. The

safe temperature limit for the electronic equipment’s

900C.This raise in temperature will take an adverse

effect on the equipment’s and sometimes fails at these

conditions. This is due to the electronic equipment’s

life time will be reduced. So the equipment maintain

safe temperature condition which is below 900C,

maintain the desired condition liquid cooling is provide

effectively.

Liquid cooling is a convective heat transfer process.

The cooling plates are classified as follows:

1) Formed Tube Cooling Plate (FTCP)

2) Deep Drilled Cooling Plate (DDCP)

3) Machined channel Cooling Plate (MCCP) 4

Form tube liquid cold plates ensure minimum thermal

resistance between the device and the cold plate by

placing the coolant tube in direct contact with the

device base plate. In this design, copper plate is

generally used, although aluminum is sometimes

employed in low power applications. In Deep drilled

cold plate the heat flux and power dissipation increases,

the contact resistance of the plate and the tube wall

become unacceptably high. In this design, deep holes

are drilled in the plane of the substrate plate. In

Machined channel cooling plate the heat flux increase,

it becomes necessary to improve the thermal

performance of the channels. In this design, channels

are machine-cut into the base plate and a cover is

soldered in place to form the flow passages.

In the literature thermal analysis of form tube,

machined channel and Deep drill cold plates at different

working environment has been done4. This shows there

is a lack of study in the behavior of three different cold

plates at same working environment. In this work the

Optimization is achieved by comparing the thermal

characteristics of three types of cold plates at same

working environment and proposed the best method

that can be adopted in different industrial equipment for

safe conditions.
