Device for indirect inter-cooling of supercharged combustion engine for motor car, has primary heat exchanger through which primary coolant flows, where coolant comprises phase change material whose phase is changed at specified temperature

摘要

#CMT# #/CMT# The device has a primary heat exchanger (26) cooling charge air (24) to be supplied to a combustion engine (12). A primary coolant i.e. water glycol mixture, flowing through the primary heat exchanger absorbs heat from the charge air and delivers the heat to a secondary coolant in a secondary heat exchanger (30). The primary coolant is liquid with a phase change material (PCM) whose phase is changed at temperature of the charge air and above the temperature of secondary coolant, and depending on heat supply or phase change enthalpy. #CMT# : #/CMT# The PCM is paraffin or alkane with carbon atoms, and comprises capsules made of polymer. An independent claim is also included for a method for indirect inter-cooling of a supercharged combustion engine. #CMT#USE : #/CMT# Device for indirect inter-cooling of a supercharged combustion engine for a motor car. #CMT#ADVANTAGE : #/CMT# The PCM allows enhancing a heat transfer capability of the coolants circulated through the primary and secondary heat exchangers, thus enhancing heat transfer capability of overall system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a device for indirect inter-cooling of supercharged combustion engine. 12 : Combustion engine 24 : Charge air 26 : Primary heat exchanger 30 : Secondary heat exchanger 34 : Surrounding air.
