Thermal dissipation system of an electric vehicle
First Claim
1. A thermal dissipation system suitable for placement within a channel defined by a vehicle that draws ambient air through the channel during operation of the vehicle, the thermal dissipation system comprising:
- a heat exchanger configured to provide cooling and heating for a cabin air conditioning system;
a first heat sink and a second heat sink arranged forward of and laterally shifted to opposing sides of the heat exchanger, each of the heat sinks configured to be in thermal contact with an operational heat emitting component of the vehicle; and
a plurality of air deflectors configured to alter a flow of the ambient air through the thermal dissipation system by transitioning between two or more configurations,wherein the plurality of air deflectors comprises a first air deflector positioned in front of the heat exchanger and spanning the gap between the first and second heat sinks,wherein in a first configuration the air deflectors are arranged to direct all the ambient air passing through the thermal dissipation system through one of the first and second heat sinks and then subsequently rejoin the ambient air after flowing through the heat exchanger and in a second configuration the air deflectors are arranged to allow a portion of the ambient air to flow directly to the heat exchanger by passing through a gap between the first heat sink and the second heat sink.

Abstract
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 and a second heat sink, which are respectively arranged at the two sides of the front part of the heat exchanger; a number of rotatable and adjustable air deflectors for changing the flow direction of the air 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.

10. An electric vehicle, comprising:
-
a vehicle chassis defining an air inlet; an air conditioning system configured to govern a temperature within the electric vehicle; a motor; a battery pack configured to provide energy to the motor; and a thermal dissipation system positioned proximate the air inlet and configured to receive air entering the air inlet, the thermal dissipation system comprising; a heat exchanger in thermal contact with the air conditioning system, a first and a second heat sink in thermal contact with the motor and the battery pack respectively, the first and second heat sinks being positioned forward of and on opposing sides of the heat exchanger, a plurality of air deflectors configured to switch between open and closed configurations, and a controller configured to direct configuration changes of the plurality of air deflectors, wherein when the thermal dissipation system is operating in a heating state the controller directs the plurality of air deflectors to divide the air received through the air inlet so that a first portion of the air passes through the first heat sink and a second portion of the air passes through the second heat sink and then the first and second portions of the air are subsequently recombined to pass through the heat exchanger. - View Dependent Claims (11, 12, 13, 14)
