Abstract

A thermoelectric dehumidifying apparatus may include a housing provided in a widthwise direction of a vehicle adjacent to a windshield glass of the vehicle and having an inlet and an outlet at an upper end thereof, a thermoelectric module including a thermoelectric element provided between the inlet and the outlet in an interior of the housing and having a surface with which cooling fins make surface-contact and an opposite surface with which heat radiation fins make surface-contact, wherein the thermoelectric element is disposed on a passage of air flowing from the inlet to the outlet such that the air introduced through the inlet passes by the cooling fins and the heat radiation fins at a same time and then is discharged through the outlet, and a fan provided in the interior of the housing, for guiding the air from the inlet to the outlet.

First claim

What is claimed is:

1 . A thermoelectric dehumidifying apparatus comprising:
a housing provided in a widthwise direction of a vehicle adjacent to a windshield glass of the vehicle and having an inlet and an outlet at an upper end thereof; a thermoelectric module including a thermoelectric element provided between the inlet and the outlet in an interior of the housing and having a surface with which cooling fins make surface-contact and an opposite surface with which heat radiation fins make surface-contact, wherein the thermoelectric element is disposed on a passage of air flowing from the inlet to the outlet such that the air introduced through the inlet passes by the cooling fins and the heat radiation fins at a same time and then is discharged through the outlet; and a fan provided in the interior of the housing, for guiding the air from the inlet to the outlet.

2 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the inlet of the housing is formed closer to the windshield glass of the vehicle than the outlet.

3 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the housing has a closed structure such that air circulates through the inlet and the outlet.

4 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the cooling fins and the heat radiation fins of the thermoelectric module extend upwards and downwards.

5 . The thermoelectric dehumidifying apparatus of claim 1 , wherein a water drainage hole is formed at a lower end of the housing.

6 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the thermoelectric module is disposed on a side close to the inlet and the fan is disposed on a side close to the outlet.

7 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the heat radiation fins of the thermoelectric module have an air contact area wider than that of the cooling fins.

8 . The thermoelectric dehumidifying apparatus of claim 1 , wherein a heat transfer mass surface-contacts the opposite surface of the thermoelectric element and a heat transfer pipe is coupled to pass through the heat transfer mass and extends in a widthwise direction of the vehicle in the interior of the housing, and the heat radiation fins are provided at an extending portion of the heat transfer pipe.

9 . The thermoelectric dehumidifying apparatus of claim 1 , wherein a plate-shaped heat transfer plate extending in a widthwise direction of the vehicle to be coupled is provided on the opposite surface of the thermoelectric element, and the heat radiation fins are coupled to the heat transfer plate.

10 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the cooling fins and the heat radiation fins are arranged to coincide with a flow direction of the air.

11 . The thermoelectric dehumidifying apparatus of claim 1 , wherein an insulation partition is provided between the cooling fins and the heat radiation fins in the interior of the housing.

12 . The thermoelectric dehumidifying apparatus of claim 11 , wherein the insulation partition surrounds the cooling fins to spatially separate the cooling fins and the heat radiation fins.

13 . The thermoelectric dehumidifying apparatus of claim 1 , wherein the fan is a cross fan disposed in a widthwise direction of the vehicle.

14 . The thermoelectric dehumidifying apparatus of claim 1 , wherein a front side and an upper side of the housing are opened with respect to the vehicle, a cross fan housing, an upper side and a rear side of which are opened with respect to the vehicle is provided, and the front side of the housing and the rear side of the cross fan housing are coupled to each other to be closed, so that air can circulate through the inlet and the outlet on the upper side of the housing.
