Abstract

An air conditioner for a vehicle including an air-conditioning case divided into a plurality of air passageways by a separation wall. A heating heat exchanger is disposed inside the air-conditioning case and exchanges heat with air to heat the interior of the vehicle. A perforated member is disposed at a downstream side of the heating heat exchanger and has a plurality of perforated holes through which the air passing the heating heat exchanger passes, and a partition wall is disposed between the heating heat exchanger and the perforated member to divide the air passageway of the air-conditioning case into a plurality of air passageways, wherein the partition wall is formed integrally with the perforated member.

First claim

What is claimed is:

1. An air conditioner for a vehicle, comprising:
an air-conditioning case including an air passageway;
a heating heat exchanger disposed inside the air-conditioning case and configured to exchange heat with air to heat the interior of the vehicle;
a perforated member disposed at a downstream side of the heating heat exchanger relative to an air back-and-forth direction and having a plurality of perforated holes through which the air passing the heating heat exchanger passes; and
at least one partition wall disposed between the heating heat exchanger and the perforated member to divide the air passageway of the air-conditioning case into a plurality of air passageways;
wherein the perforated member is an electric heater, and the at least one partition wall extends through the electric heater in the air flow back-and-forth direction of the electric heater and is slidably connected with the electric heater.

2. The air conditioner according to claim 1 , wherein the at least one partition wall includes a front partition wall formed on a front surface of the electric heater and a rear partition wall formed on a rear surface of the electric heater opposite the front surface.

3. The air conditioner according to claim 2 , wherein the front partition wall on the front surface of the perforated member extends away from the perforated member by a larger distance than the rear partition wall formed on the rear surface of the perforated member.

4. The air conditioner according to claim 1 , wherein the at least one partition wall is arranged higher than a center of the electric heater in a vertical direction, wherein the vertical direction is parallel to the front and rear partition walls.

5. The air conditioner according to claim 4 , wherein the partition wall is arranged at a 2:3 part of the electric heater in the vertical direction, and
wherein an interval between the heating heat exchanger and the perforated member is within a range of 2 mm to 20 mm, and more preferably, the interval between the heating heat exchanger and the perforated member is 10 mm.

6. The air conditioner according to claim 1 , wherein the perforated member is an auxiliary heating heat exchanger or a dummy member.

7. The air conditioner according to claim 1 , wherein the partition walls are detachably combined with the perforated member.

8. The air conditioner according to claim 1 , wherein the perforated member comprises: a first combining groove formed in a side facing the heater core wherein the partition wall is inserted into the first combining groove; and a second combining groove 134 formed in the opposite side wherein the separation wall of the air-conditioning case is inserted into the second combining groove.

9. The air conditioner according to claim 1 , wherein the at least one partition wall is made of a material with a higher degree of heat resistance than that of the air-conditioning case.

10. An air conditioner for a vehicle, comprising:
an air-conditioning case including an air passageway;
a heating heat exchanger disposed inside the air-conditioning case and exchanging heat with air to heat the interior of the vehicle;
an electric heater disposed at a downstream side of the heating heat exchanger and having a plurality of perforated holes through which the air passing the heating heat exchanger passes; and
a front partition wall formed on a front surface of the electric heater and a rear partition wall formed on a rear surface of the electric heater opposite the front surface;
wherein a bridge unit is disposed between fixing portions of the at least one partition wall and the electric heater, wherein the bridge unit includes a first support part having a first component overlying the front partition wall and a second component at a right angle relative to the first component, and a second support part having a first component overlying the rear partition wall and a second component at a right angle relative to the first component; and
a connection part connecting the first support part and the second support part with each other and inserted and joined into a fixing part of the electric heater.

11. The air conditioner according to claim 1 , wherein indoor air and outdoor air are separately introduced into the air passageway of the air-conditioning case, and the air passageway is divided into an upper air passageway and a lower air passageway by a separation wall.

12. The air conditioner according to claim 11 ,
wherein the electric heater includes heat generating units for generating heat by application of electric power and a heat radiating unit exchanging heat with air.

13. The air conditioner according to claim 12 , wherein the heat generating units of the electric heater are arranged to be spaced apart from each other in a vertical direction.

14. The air conditioner according to claim 12 ,
wherein the heat generating units of the electric heater are arranged symmetrically in a vertical direction.

15. The air conditioner according to claim 12 , wherein the heat generating units of the electric heater are formed in odd numbers, and
wherein the heat generating units of the electric heater are arranged much more at a lower part than at an upper part on the basis of the separation wall.

16. The air conditioner according to claim 12 , wherein the electric heater is mounted in such a way that a center of the electric heater is located at the separation wall in a vertical direction.

17. The air conditioner according to claim 12 , wherein a heater core for heating air by a cooling water heat source is included in the air-conditioning case, and the electric heater is integrally combined with the downstream side of the heater core in an air flow direction,
wherein the heater core comprises: a first header tank and a second header tank disposed side by side to be spaced apart from each other;
a cooling water pipe disposed on the first header tank or the second header tank for introducing and discharging cooling water;
a plurality of tubes of which both ends are fixed to the first header tank and the second header tank to form a cooling water passageway;
pins interposed between the tubes; and
a pair of side plates for supporting both sides of an assembly of the tubes and the pins, and
wherein the electric heater includes a terminal unit for applying electric power to the heat generating units, the heat radiating unit is formed in a plate shape to fix the heat generating units, and end portions of the heat generating units and the heat radiating unit are supported by a housing.

18. The air conditioner according to claim 10 , wherein the partition wall is arranged higher than a center of the perforated member in a vertical direction.

19. The air conditioner according to claim 10 , wherein the partition wall is made of a material with a larger amount of heat resistance than that of the air-conditioning case.
