摘要:
An automotive heat exchanger (1) has respective flowpath arrays (2,3) for a first fluid medium and a second fluid medium (air). A series of tubes (2) for the first fluid medium are formed of joined mating plates (4,5), the tubes (2) having open ends and a flowpath extending between the open ends, adjacent tubes (2) having spaced external surface portions defining the flowpath array (3) for the air fluid medium. The tubes (2) advantageously have relatively wide open mouth portions (4a) leading to a narrower tube width (h) extending between the open ends.
摘要:
A vehicle thermal management system includes a refrigerant circuit system and heat exchanger(s) for heat exchange between the refrigerant circuit and the engine coolant circuit of the vehicle and/or the engine emission exhaust system. The system provides for enhanced thermal management of vehicle systems.
摘要:
A control arrangement for a vehicle heating ventilation or air conditioning (HVAC) system, the control arrangement comprising an inner control device and an outer control device, the outer control device being rotatable about the inner control device.
摘要:
Air distribution apparatus for a vehicular heating, ventilation, or air conditioning (HVAC)/climate control system, includes a primary distribution arrangement (1) reconfigurable to direct air to alternative outlet zones including two or more of a passenger footwell zone, passenger cabin vents and a vehicle windscreen. Ducting directs air flow to the alternative outlet zones; first and second rotary air distribution devices (4, 5) are adjustable rotationally between alternative configurations to distribute air into the ducting arrangement in alternative outlet configurations; re-configuration of one of the devices is accompanied by complementary re-configuration of the other device and/or air distribution devices are located immediately adjacent a cover panel or facia, the cover panel of facia including a user accessible control to control operation of the air distribution devices.
摘要:
A liquid coolant circuit carries engine coolant and includes a radiator for dissipating heat from the engine coolant. A charge air delivery system delivers charge air from a compressor to motive power production apparatus. A two stage heat exchanger arrangement acts on the charge air, the two stage arrangement comprising a first stage liquid cooled heat exchanger stage and a second stage, gas cooled, heat exchanger stage downstream of the first stage in the charge air system.

摘要:
A condenser (1) primarily for use in an automotive air conditioning system has a first and second heat transfer tube arrangements (4a,4b) in upstream and downstream portions of the condenser of different hydraulic diameters. The hydraulic diameters of the downstream tube arrangement is typically of larger value. The arrangement provides amelioration of reduced flow 'choking' effects, particularly for sub-cooled liquid refrigerant passes.
