Structure for cooling heating element
A structure for cooling a heat element includes a heat element box containing a heat element and forms an air passageway therebetween, an intake duct connecting a passenger compartment and the air passageway, a discharge duct connecting the air passageway and a vehicle exterior, and a wall on a vehicle body. The intake duct has a water reserving portion for accumulating a liquid entering from the passenger compartment. The intake duct has an expansion portion and has a discharge hole of the liquid. The wall is provided to face the discharge hole so that the liquid discharged through the discharge hole moves downward along a surface of the wall.
1. A structure for cooling a heat element comprising:
a heat element box that contains a heat element and forms an air passageway between the heat element box and the heat element;
an intake duct that fluidically connects a passenger compartment and the air passageway with each other in such a way that air in the passenger compartment flows into the air passageway through the intake duct to cool the heat element, the intake duct being provided with a water reserving portion that can accumulate a liquid entering from the passenger compartment, the intake duct having an expansion portion that forms a portion of the water reserving portion, and the expansion portion being provided with a discharge hole of the liquid;
a discharge duct that fluidically connects the air passageway and a vehicle exterior to discharge the air in the heat element box to the vehicle exterior, and
a wall that is provided on a vehicle body to face the discharge hole so that the liquid discharged through the discharge hole moves downward along a surface of the wall.
2. The structure for cooling a heat element according to claim 1 , wherein
the intake duct and the heat element box are disposed in a heat element storage space that is formed between the passage compartment and a luggage compartment, and wherein
the wall defines the heat element storage space from the luggage compartment.
3. The structure according to claim 2 , wherein
a surface of the expansion portion, which is formed with the discharge hole, and the wall are slanted relative to each other in such a way that a clearance is formed between the discharge hole and the wall.
4. The structure according to claim 3 , wherein
the expansion portion has a configuration shaped like one of a U-letter and a V-letter seen from a discharge hole side.
5. The structure according to claim 4 , wherein
the intake duct is provided with a projecting portion that projects downward from a bottom surface of the intake duct to define a bottom surface of the expansion portion from a rest of the bottom surface of the intake duct.
6. The structure according to claim 5 , wherein
the heat element is a battery.
7. The structure according to claim 6 , wherein
a lower edge of the wall and a floor panel of a vehicle body form a space through which the liquid passes to an inner space formed by a spare wheel recess portion of the floor panel.
8. The structure according to claim 1 , wherein
a surface of the expansion portion, which is formed with the discharge hole, and the wall are slanted relative to each other in such a way that a clearance is formed between the discharge hole and the wall.
9. The structure according to claim 8 , wherein
the expansion portion has a configuration shaped like one of a U-letter and a V-letter seen from a discharge hole side.
10. The structure according to claim 9 , wherein
the intake duct is provided with a projecting portion that projects downward from a bottom surface of the intake duct to define a bottom surface of the expansion portion from a rest of the bottom surface of the intake duct.
11. The structure according to claim 10 , wherein
the heat element is a battery.
12. The structure according to claim 11 , wherein
a lower edge of the wall and a floor panel of a vehicle body form a space through which the liquid passes to an inner space formed by a spare wheel recess portion of the floor panel.
13. The structure according to claim 1 , wherein
the expansion portion has a configuration shaped like one of a U-letter and a V-letter seen from a discharge hole side.
14. The structure according to claim 13 , wherein
the intake duct is provided with a projecting portion that projects downward from a bottom surface of the intake duct to define a bottom surface of the expansion portion from a rest of the bottom surface of the intake duct.
15. The structure according to claim 14 , wherein
the heat element is a battery.
16. The structure according to claim 1 , wherein
the intake duct is provided with a projecting portion that projects downward from a bottom surface of the intake duct to define a bottom surface of the expansion portion from a rest of the bottom surface of the intake duct.
17. The structure according to claim 16 , wherein
the heat element is a battery.
18. The structure according to claim 17 , wherein
a lower edge of the wall and a floor panel of a vehicle body form a space through which the liquid passes to an inner space formed by a spare wheel recess portion of the floor panel.
19. The structure according to claim 1 , wherein
the heat element is a battery.
20. The structure according to claim 1 , wherein
a lower edge of the wall and a floor panel of a vehicle body form a space through which the liquid passes to an inner space formed by a spare wheel recess portion of the floor panel.
