Title

Analysis Of Thermal Response Of A Portable Blood Cooling Device

Abstract

This paper presents the three-dimensional (3D) modeling and simulation of heat transfer within a portable blood cooling system with respect to space and time. The cooling system under study includes a. cooler box with two cooling cylinders and eight blood bags. The cooler has the shape of a rectangular box with walls made of thermal-insulation material. The cooling cylinders protrude into the inner space through the bottom of the cooler box. Eight blood bags are arranged around these two cooling cylinders. The cooling cylinders use desiccant absorbing agents in combination with evaporative processes under vacuum pressure to achieve the cooling effect. Transient thermal response of the system is simulated by employing a computational approach. The computational domain includes the air inside the cooler box and the blood inside the blood bags. Heat from the surroundings penetrating the system through the insulation walls of the cooler box is included in the model. It is assumed that initially the blood is at the uniform ambient temperature. Once the cooling cylinders are activated, they draw heat from the air and the blood inside the cooler box. A lumped-parameter model is used to model the heat drawn by the cooling cylinder. The resulting solution of temperature distribution within the blood bags and the air in the cooler box is presented in the form of graphical visualization. Representative temperatures within the blood bags are presented as functions of time during a period of 12 hours. The computational model and results will be useful for the development and optimization of the design of portable cooling devices for the transportation of blood and similar biological tissues such as an organ for transplant.
