摘要:
Provided is an air-conditioning device (10) for a vehicle, including: a cooling device (16) configured to cool air passing through a duct (12); a heater core (18), which is arranged in the duct on a downstream side of airflow with respect to the cooling device, and is configured to use an engine coolant as a heat source to heat the air; a water valve (22) provided in a coolant circulation system (26) on an upstream side of the heater core; and a control device configured to control those components, in which the control device is configured to decrease an opening amount of the water valve in a predetermined cooling mode. The control device is configured to, when the opening amount of the water valve is decreased, decrease a rotational speed of a compressor (50) of the cooling device, and increase a target evaporator temperature of an evaporator of the cooling device, thereby decreasing cooling performance of the cooling device.

An air conditioning device for vehicle includes a first water-refrigerant heat exchanger, a second water-refrigerant heat exchanger, a first bypass passage, and a second bypass passage. The first bypass passage branches at a point of a coolant passage from a cooling portion of a heating component in the vehicle to the second water-refrigerant heat exchanger, and the first bypass passage is capable of being communicated with the coolant passage at an upstream side of the first water-refrigerant heat exchanger. The second bypass passage branches at a point of the coolant passage from a heater core to the first water-refrigerant heat exchanger, and the second bypass passage is capable of being communicated with the coolant passage at a downstream side of the first water-refrigerant heat exchanger. A part of the first bypass passage which includes a downstream end and a part of the second bypass passage which includes an upstream end are shared.

Electric vehicle thermal management systems and electric vehicles using the thermal management system, are disclosed. A passenger cabin is heated by the heat dissipated from a battery and /or a motor. A cooling circuit in the management system fluidly connects the battery 101, the motor 102 and a first radiator 104 in series. The first radiator 104 provides a heat source to the passenger cabin by means of the heat dissipated from the battery 101 and/or the electric motor 102. Under certain conditions, the electric motor is selectively separated from the cooling circuit, so that when the passenger cabin needs to be heated, the thermal management system can provide heat to the passenger cabin without affecting the heat dissipation of the battery 101.
摘要:
A vehicle air conditioning device has an air-conditioning unit (2 or 3) including a temperature regulation unit (3) having an evaporator (1) and a blower unit (2) including a blower (5). The blower unit (2) is offset to a side of the temperature regulation unit (3). A deflection guide (7) to deflect a flow of air is provided upstream of the evaporator in a flow of air flowing into an inflow plane (1a) of the evaporator from the blower. The deflection guide has a plate-like defection portion (71) inclined with respect to the inflow plane, and a support portion (72) supporting the deflection portion by extending from the blower unit. A gap (G1) is provided between the support portion and the evaporator. Air that has collided with the deflection portion is changed in flow direction to head for the blower side of the inflow plane. Air thus flows more to the blower side of the inflow plane. Consequently, a vehicle air conditioning device having a duct structure to flow air between the blower and the evaporator is provided, which duct structure has low fluid resistance and is relatively easy to manufacture because no complex structure is involved.

The present disclosure relates to a thermal dissipation system of an electric vehicle that includes: a heat exchanger arranged at the front part of the electric vehicle for providing heating or cooling to an air conditioning system of the electric vehicle; a first heat sink (220) and a second heat sink (230), which are respectively arranged at the two sides of the front part of the heat exchanger (210); a number of rotatable and adjustable air deflectors (121, 131) for changing the flow direction of the air (250) flowing through the heat dissipation system. Temperature sensors are included within the thermal dissipation system for sensing the working temperatures and the environmental temperatures of a battery pack and a motor of the electric vehicle. Opening and closing states of the air deflectors are adjusted in accordance with data provided by the temperature sensors.
