Abstract

A heat dissipation device for a vehicle battery includes a box for receiving therein at least a vehicle battery; an upper lid disposed above the box and separated from the box by a waterproof plastic sheet; a microspray heat dissipation pipe disposed on a side of the box and having at least a microspray nozzle in communication with an inside of the box; and at least a non-return exhaust duct disposed on an opposing side of the box and in communication with the inside of the box.

First claim

What is claimed is:

1 . A heat dissipation device for a vehicle battery, comprising:
a box for receiving therein at least a vehicle battery; an upper lid disposed above the box and separated from the box by a waterproof plastic sheet; a microspray heat dissipation pipe disposed on a side of the box and having at least a microspray nozzle in communication with an inside of the box; and at least a non-return exhaust duct disposed on an opposing side of the box and in communication with the inside of the box.

2 . The heat dissipation device for a vehicle battery according to claim 1 , wherein the microspray heat dissipation pipe comprises:
a condensation pipe having the at least a microspray nozzle in communication with the inside of the box and having an end in communication with a cool air generation source; a temperature-controlled throttle valve disposed between the condensation pipe and the cool air generation source; and an enclosing case for enclosing the condensation pipe.

3 . The heat dissipation device for a vehicle battery according to claim 2 , wherein the cool air generation source is an air conditioning system of a vehicle.

4 . The heat dissipation device for a vehicle battery according to claim 2 , wherein the cool air generation source is a standalone air conditioning unit.

5 . The heat dissipation device for a vehicle battery according to claim 2 , further comprising a dehumidifying unit disposed between the temperature-controlled throttle valve and the cool air generation source.

6 . The heat dissipation device for a vehicle battery according to claim 5 , wherein the dehumidifying unit takes in moisture with activated carbon.

7 . The heat dissipation device for a vehicle battery according to claim 1 , wherein the non-return exhaust duct comprises:
an exhaust pipe having an end in communication with the inside of the box and another end provided with a non-return exhaust vent; and an exhaust fan disposed in the exhaust pipe and positioned proximate to the non-return exhaust vent.

8 . The heat dissipation device for a vehicle battery according to claim 1 , wherein a hanging-fixing element is disposed on an outer wall surface of the box.

9 . The heat dissipation device for a vehicle battery according to claim 8 , wherein the hanging-fixing element is a ring bolt.

10 . The heat dissipation device for a vehicle battery according to claim 1 , wherein a waterproof, dustproof protective element is disposed between the box and the microspray heat dissipation pipe and between the box and the non-return exhaust duct.
