Модель распределения теплового потока в теплообменнике аппарата искусственного кровообращения

Abstract

The 3D-model of the distribution of the heat flow for device of cardiopulmonary bypass, which allows you to control the blood temperature at the outlet of the heat exchanger for cardiopulmonary bypass are purposed. The geometric shape of the heat exchanger in the MSC Sinda system is a cube that contains a heating medium – water and heated coolant tube – blood. Implementation of the heat flow distribution in the heat exchanger model for cardiopulmonary bypass in the MSC Sinda system gives the temperature distribution at the inlet and outlet of the heat exchanger. In accordance with the physical and computational model for the once-through design of the heat exchanger in the process of warming the blood decreases the amount of heat that is given to water. This result is consistent with the heat balance equation in the absence of counter-movement of coolant – water and blood in a heat exchanger for the device of cardiopulmonary bypass.
