Ventilation Module for Ventilation Seat

A ventilation module for a ventilation seat for a vehicle, the module comprising:

• a thermoelectric air-conditioning part having a thermoelectric unit performing heat absorption and heat generation by using a Peltier effect when electric power is applied, a cooling unit provided at a first side of the thermoelectric unit, and a heat dissipation unit provided at a second side of the thermoelectric unit;
• a cool air duct, the cooling unit being located in the cool air duct, wherein the module is configured so that air that is supplied from a blower is cooled by the thermoelectric air-conditioning part, passes through a cooling fin of the cooling unit, and is discharged to an interior of the vehicle through a seat cushion;
• and
• a heat dissipation path, the heat dissipation unit being located in the heat dissipation path, wherein the module is configured so that air that is supplied from the blower is heated by the thermoelectric air-conditioning part, passes through a heat dissipating fin of the heat dissipation unit, and is discharged through the heat dissipation path;
• wherein the heat dissipating fin combined with the heat dissipation unit of the thermoelectric air-conditioning part is provided by being stacked in one or more layers, so that air introduced to the heat dissipation unit can pass through one layer and then pass through a remaining layer;
• and
• wherein by increasing a resistance to airflow in the heat dissipation unit more than that in the cooling unit, an amount of airflow flowing to the cooling unit is increased more than that flowing to the heat dissipation unit.
