Products / Liquid Cooled Cold Plates / Blister Cold Plates

AavBlister Cold Plates

Liquid Cooled Cold Plate Aavid Thermalloy AavBlister cold plates represent an important innovation in cold plate design. Rather than milling channels inside a base plate and covering them with a flat cover plate, Blister technology stamps the channels into the cover plate eliminating base plate machining and greatly lowering manufacturing costs for higher volume applications. Brazing creates a leak free joint between the base and cover plate. Unlike milled cold plates, the blister channels allow greater flexibility to drill mounting holes in the under side of the heat sink without regard for the location of the liquid channels. The inside of the Blister channel uses offset fin structures to enhance thermal transfer performance

Performance

Performance of a cold plate is dependent on a number of factors including power dissipation of the device cooled, cooling fluid, size of the cold plate along with the fluid and ambient temperatures. Below are two examples to illustrate the performance of Aavid blister cold plate technology. The examples shown use pure water as the cooling fluid. Temperatures are measured in the center of the device.

Example 1:
Single IGBT 162mm x 122mm
Power Dissipation: 2.5kW
Coolant: Water
Inlet water temp: 40° C
Flow Rate: 6 liters per min
Example 2:
Four IGBTs 108mm x 62mm
Power Dissipation: 4kW
Coolant: Water
Inlet water temp: 40° C
Flow Rate: 6 liters per min

310 x 150mm Blister LCP with a
162 x 122mm IGBT - 2.5kW
310 x 150mm Blister LCP with a
4 x 108 x 62mm IGBTs - 4kW
Results (See Graph)
Rth = 14°C/kW
T sink = 75° (measured at the center
of the module)
DP = 0.08 bar (8 kPa) 		Results (See Graph)
Rth = 7° C/kW
T sink = 68° (measured at the center
of the module)
DP = 0.16 bar (16 kPa)
