a cover configured to cover an upper surface of a vehicle controller;
a heat transfer part adjacent to a heating element in the vehicle controller;
a heat pipe disposed in a horizontal direction of the vehicle controller heat dissipation module and including a first portion in contact with the heat transfer part to receive heat from the heat transfer part generated by the heating element;
a heat dissipation fin in contact with a second portion of the heat pipe and configured to emit heat from the heat pipe;
a first fan disposed in a side surface of the vehicle controller and configured to introduce air into the vehicle controller; and
a second fan configured to be disposed in or adjacent to an opening in the cover above the second portion of the heat pipe and heat dissipation fin to discharge air from inside the vehicle controller to an outside of the vehicle controller,
wherein:
the heat transfer part is formed of a high thermal conductivity material and is located between the heating element and the heat pipe to transfer the heat generated by the heating element to the heat pipe; and
the cover includes an outer surface, facing the outside of the vehicle controller, and an inner surface, wherein a protruding portion of the cover, thicker than at least one other portion of the cover, extends from the inner surface of the cover into contact with the first portion of the heat pipe.
2 . The vehicle controller heat dissipation module of claim 1 , wherein:
the heat dissipation fin is disposed to extend from the heat pipe in a vertical direction of the vehicle controller heat dissipation module; and
the heat pipe passes through and is in contact with the heat dissipation fin.
