An antenna comprises at least one cold plate serving as main mechanical structure and a set of transmission and reception modules, the modules supplied with electrical power by an electrical power distribution circuit connected to a power source delivering a power supply voltage, the distribution circuit formed by conductive tracks deposited by plasma spraying on the cold plate and crossing the cold plate to reach connection points to the transmission and reception modules.

Compact electronic scanning antenna

This temperature regulation apparatus comprises a heat pump () comprising a main compression circuit () for a refrigerant fluid taking heat from a cold source () and transferring it to a hot source (). The cold source () comprises a first heat exchanger () for exchanging heat between the refrigerant fluid and a liquid coolant thermally coupling the main refrigerant circuit () to a first secondary coolant circuit (). The first secondary circuit () has selective connection means () for selectively connecting it to the upstream and downstream ends (A,B) of a 'heater' branch () of a cooling liquid circuit () of an exothermal part of the vehicle. The exothermal part is preferably a heat engine of the vehicle. The invention is applicable to air conditioning a motor vehicle cabin.

Optimized heat pump apparatus for regulating motor vehicle temperature

According to the method, heat delivered to the cabin (H) comes from a hot source ( ) of a heat pump ( ) comprising a main refrigerant circuit ( ) taking heat from a cold source ( ) to transfer it to the hot source ( ). Heat taken from the cold source ( ) comes from a flow of air recycled from the cabin. The cold source ( ) has a refrigerant/coolant heat exchanger ( ) thermally coupling the main circuit ( ) to a first secondary coolant circuit ( ) capable of being selectively connected to an outside heat exchanger ( ) and to a cold heat exchanger ( ). Air flow circuits have an inlet for admitting air recycled from the cabin, an outlet for delivering air to the outside of the vehicle, first connection means for connecting the recycled air inlet to the upstream end of the cold heat exchanger ( ), and second connection means for connecting the downstream end of said cold heat exchanger ( ) to the outside outlet.

Method and apparatus for regulating the temperature of a motor vehicle cabin

A vehicle heating and cooling system having a first coolant loop selectively connecting an engine cooling system with a heater core or a first coolant/refrigerant heat exchanger, a second coolant loop connecting a second coolant/refrigerant heat exchanger and the heater core to warm a passenger compartment of the vehicle. The system also includes a refrigerant loop that provides for conventional cooling of the passenger compartment of the vehicle, as well as operating as a heat pump, together with the coolant loops, to provide heat to the vehicle passenger compartment.
