Liquid Cold Plate For Electric Locomotive

liquid cold plate is through the structure of compact and relatively thin plate-like, strip metal internal layout of the fluid channel, so that the fluid and liquid cold plate between the convection heat transfer, thereby dissipating the surface of the liquid cold plate high power electronic components of the thermal power consumption. The application advantage of liquid cold plate depends on, unit area can dissipate more quantity of heat, consequently heat sink structure can miniaturize. The liquid cold plate is designed to maintain the low temperature required by the internal components through continuous liquid heat exchange through direct contact with the copper pipe. At the same time, the copper pipe of good welding, excellent sealing performance, so that customers less worry about leakage.The liquid cold plate of medical equipment is not only a heat dissipation device, but also a delicate structural part.

The liquid cold plate made using buried welding technology can effectively avoid the leakage risk of the infusion pipeline, and the liquid flow is large, and the conduction heat resistance is low, and the double-sided device can be installed. Lori can provid you with the thermal design, structural design, pipework assembly design of liquid and liquid cold plate and one-stop supplementary services.

The heat pipe on this  liquid cold plate is used exposed pipe technique. The techniques for  the  liquid cold plate include the exposed pipe technique, half buried pipe techniques, sandwiched pipe technique. Let us introduce what is full buride pipe techique for liquid cold plate , please see the following introduction. 

Exposed-pipe technique: This technique applies to devices to be installed on one side. Copper pipes are pressed to deform into the grooves within an aluminum plate and then a fly-cut is applied to the surface. This allows the quick removal of heat due to the high thermal conductivity of copper pipes. Meanwhile, the lightweight of aluminum can reduce the total weight and keep the cost to a reasonable extent.

Full-buried-pipe technique: The filler is a type of highly conductive epoxy resin which is imported from the US. When the temperature difference between two sides of a device is not critical, the  liquid cold plate can be applied to either just one side or both sides of the device. Since the copper pipe thickness is not affected by any secondary machining and the application safety is ensured due to the protection of the filler, this technique is especially suitable for  liquid cold plate applications which use refrigerant as the cooling medium.

Half-buried techniques: This technique is suitable for the combination of copper plate + copper pipes. It can reduce the liquid cold plate thickness and generate the weight reduction effect.

Sandwiched-tube technique: There are tubes between two plates and this technique is simple with lower cost. The combination could be aluminum base plate + aluminum tubes/copper tubes/SUS tubes.
