FIELD: heat exchange.
SUBSTANCE: invention relates to heat exchangers for vehicles. Heat exchange unit includes a storage battery, an electric motor and a transmission system, a heat pump and a heat exchanger. Heat pump is used for air conditioning. Heat pump includes an electric compressor which compresses the coolant. Electric compressor is made with possibility to be actuated with electric energy from accumulator battery. Heat exchanger is configured to exchange heat between the coolant and the lubricating oil lubricating the transmission system.
EFFECT: reduced electric power consumption in electric compressor.
