Abstract

This study of the effects of cold chamber parameter on gas flow in thermal transpiration pumps focuses on the installation of a cooling system to the cold chamber design. This is since a greater temperature in the hot chamber and a lower temperature in the cold chamber might result in a temperature gradient, a pressure difference, and gas flow in the Knudsen pump. As the goal of the cooling system is to help the cold chamber in maintaining a cold temperature without severe temperature increases from hot gas temperatures, the cooling system helps the cold chamber to maintain a cold temperature. TEC1-12706 Utilizing the cold side of the Peltier and a water-cooling system at the hot side of the Peltier, a Peltier is utilised in the cooling system to obtain cold temperatures. Zero changes in the hot chamber, the addition of rockwool, and the addition of both rockwool and wiremesh are investigated. The finding is made by analysing the temperature difference between two regions in which the characteristics of different types of hot chambers are analysed with and without a cooling system. The pressure of the example with the highest temperature gradient is observed to determine the existence of pressure flow. Consequently, the thermal transpiration pump can be improved by the implementation of several suggestions to archive a more efficient gas flow.
