Title:
HEAT EXCHANGER FOR A CLOSED COMPARTMENT
Document Type and Number:
WIPO Patent Application WO2002065823
Kind Code:
A8
Abstract:
A heat exchanger (1) for a closed compartment, such as the compartment in a cubicle, comprises a heat exchanger element (16, 17) of heat-conducting metal sheet (18, 19) which forms longitudinal ducts communicating with the ambient air, and transverse ducts (21, 22) communicating with the compartment. A first fan means is mounted in the compartment to feed hot air from the compartment through the transverse ducts (21, 22). A second fan means (30) is separated from the compartment and arranged to feed ambient air through the longitudinal ducts for the purpose of carrying off heat transferred from the hot air in the compartment via the metal sheet (18, 19), to the ambient air and thus cooling the compartment. The heat exchanger element is divided into a first unit (16) arranged in an inlet end of an air duct communicating with the ambient air and the longitudinal ducts, and a second unit (17) arranged in an outlet end of the air duct, and the second fan means (30) is arranged in the air duct between the first and second units (16, 17).
