Tittle:
Compact closed loop evaporator for effective heat transfer
Summary:
Research team from a distinguished Slovak university has developed unique concept of compact closed loop evaporator for the extraction of heat from various sources, which are in close contact through heat pipes and heat exchanger. The proposed technology is applicable for cooling systems in the field of electronics, metallurgy, ceramics or in data centers. The university is seeking partners through licensing agreement or financial agreement.
Description:
The proposed technology utilizes from its innovative design and production method to achieve higher efficiency, reliability and durability. Construction solution of the compact closed loop evaporator is based on a metal monoblock with the vertically oriented opening. Water or liquid hydrocarbons (e.g. ethanol) can be used as a cooling medium. The system is working without a pump, cooling medium flow is ensured by the thermosiphon effect. This unique concept uses heat pipes and heat exchanger in close contact with the heat source, enabling efficient and reliable heat diversion.

With the increased power of chips being used in computing, there is a need for a more effective method of heat diversion from the active unit. PCs today are using simple fin refrigeration with active air fan cooling. The main weakness of these systems is the need for active cooling or the dependence on the power source. Any possible fan failure leads to overheating of the processor and eventually to its permanent damage. Cooling based on the principle of closed loop evaporator is completely independent of external power source. This advantage is also significant for cooling systems in high-performance electrical engineering and computing. Additionally, there is a possibility to electrically isolate the evaporator from the capacitor, making the manipulation in this field possible without the danger of high voltage. Cooling systems in metallurgy and ceramics industry are focused on heat diversion through contact systems, which also includes the proposed technology. The main advantages in this application present comparable capacities of heat transfer at significant savings in operation and reliability of the system. Many competitive advantages are also presented for application as cooling system for data centers.
The university is looking for industrial partners to cooperate via licensing agreement or financial agreement.


Current and Potential Domain of Application:
· Computer cooling systems
With the increased power of chips being used in computing, there is a need for a more effective method of heat diversion from the active unit.

Any possible fan failure leads to overheating of the processor and eventually to its permanent damage. Cooling based on the principle of closed loop evaporator is completely independent of external power source.
· Cooling systems in high-performance electrical engineering and computing
In addition to the significant advantage of the independency on external power source, there is a possibility to electrically isolate the evaporator from the capacitor, making the manipulation in high-performance electrical engineering possible without the danger of high voltage.
· Cooling devices and systems in metallurgy and ceramics industry
Cooling systems in metallurgy and ceramics industry are focused on heat diversion through contact systems, which also includes the proposed technology. The main advantages in this application present comparable capacities of heat transfer at significant savings in operation and reliability of the system.
· Cooling systems for data centers
This is a rapidly growing field and the primary requirement is to ensure the safety and availability of stored data. With the increasing performance requirements of data centers increases also the required cooling capacity. Most of the data centers are using the method of cooling the air, which is later used for cooling the hardware itself. Independency of the compact closed loop evaporator system on external power source and subsequent reliability and easy maintenance is a significant competitive advantage in this field, which takes reliability as its primary objective.
