System for cooling a diesel exhaust fluid
A cooling system for cooling diesel exhaust fluid (DEF) for an off-road vehicle is provided. The system includes a DEF tank configured to hold DEF. The system includes a cooling interface configured to interface with the DEF. The system further includes a thermoelectric device disposed exterior to the DEF tank, wherein a first portion of the thermoelectric device is coupled to the cooling interface. The thermoelectric device is configured to draw heat from the cooling interface to cool the DEF. The system still further includes a heat sink coupled to a second portion of the thermoelectric device opposite the first portion. The heat sink is configured to draw heat away from the thermoelectric device.
1. A cooling system for cooling diesel exhaust fluid (DEF) for an off-road vehicle, comprising:
a DEF tank configured to hold DEF;
a fluid circuit external to and coupled to the DEF tank;
a pump disposed along the fluid circuit and configured to pump the DEF to and from the DEF tank along the fluid circuit;
a cooling interface disposed along the fluid circuit, wherein the cooling interface is configured to interface with the DEF;
a thermoelectric device disposed exterior to the DEF tank, wherein a first portion of the thermoelectric device is coupled to the cooling interface, and wherein the thermoelectric device is configured to draw heat from the cooling interface to cool the DEF; and
a heat sink coupled to a second portion of the thermoelectric device opposite the first portion, and wherein the heat sink is configured to draw heat away from the thermoelectric device.
2. The system of claim 1 , wherein the heat sink is configured to be disposed within an air intake duct of the off-road vehicle, and wherein an air flow through the air intake duct is configured to cool the heat sink.
