2017-12-30 Ukraine: New Heat Pipes Designs with Constant and Variable Conductions Properties


New Heat Pipes Designs with Constant and Variable Conductions Properties

Description of the project offered: 
Heat Pipes Laboratory of National Technical University of Ukraine KPI is seeking partners to co-develop or application a new heat pipes designs with constantan and variable conductions properties for space and ground technologies. Laboratory is seeking a range of academic and industrial partners, including a consortium, to co-develop and pilot such equipment. 

Description of the project
Contemporary aerospace and ground equipments are characterized by a continuous growth of power consumption and increase of their lifetime. New space satellites designs, from telecommunication satellite to microsatellite, include thermal stabilization systems which are based on heat pipes (HPs). The HPs are devices of very high thermal conductance and have successful experience of space craft and ground equipment applications. 

However, the evolution of electronic devices opens new problems with ensuring their thermal modes. Such problems are caused by the need of the reliable passive thermal control system for a narrow range of equipments operation (for example, for navigation devices, optical devices and chemical batteries). Moreover new electronics devices characterized by high dissipated heat flux. 

In this aspect, the constant conduction (CCHP) and the variable conduction heat pipe (VCHP) is a prime example of these problem solutions. So, recently, VCHPs emerge as solutions for thermal control problems on space crafts. The widest application of VCHPs and a major use of basic heat pipe units are in the removal of heat from electronic components and other heat-generating devices on satellites. The VCHP offers temperature control within narrow limits, in addition to the simple heat transport function performed by basic heat pipes. As well the VCHP has a unique feature that sets it apart from other types of heat pipe. This is its ability to maintain a device mounted at the evaporator at a near constant temperature, independent of the amount of power being generated by the device.

However, the growth of VCHPs application for space technologies requires the improvement of their reliability, the simplification of their design, the increase of their efficiency at decrease of weight and overall parameters. In this direction along with conventional VCHPs constant conduction heat pipes (CCHPs) could be used. In this case, CCHP technology provides the VCHPs by physical properties of heat carrier and special combination of capillary-porous structure characteristics. Ground tests and the first results of a space mission showed the perspective of such solutions.

Direction will focus on developing technologies for production VCHP and CCHP. Moreover, creation and piloting full scale energy efficient equipments based on VCHP and CCHP. As well, project will include an approaches and ways for implementation technical documents and standards. As a results, this technology will be implemented on European and world markets.
The works in direction new designs of VCHP and CCHP will run for 2-3 years. They need in participation of 3…5 organizations.
