Abstract

Disclosed is a turbo blower with an impeller unit-cooling fan for a fuel cell and, more particularly, a turbo blower with an impeller unit-cooling fan for a fuel cell, the turbo blower improving efficiency and durability of an impeller unit by preventing an increase in temperature by cooling the impeller unit, which generates high-pressure air, using a cooling structure that uses both of an air cooling type and a water cooling type.

Claims

1. A turbo blower (1) with an impeller unit-cooling fan for a fuel cell for solving problems with a turbo blower for a fuel cell that are generated by high-temperature heat by maximizing cooling effect of the turbo blower for a fuel cell and improving efficiency and durability, by cooling the second air suction compartment (120) using both of air cooling and water cooling by positioning and coupling the impeller unit (120) producing compressed air in the blower casing unit (100) divided into a first air suction compartment (110) and the second air suction compartment (120), the turbo blower (1) comprising:

a blower casing unit (100) that guides flow and discharge of suctioned air; and

an impeller unit (200) that is disposed in the blower casing unit (100), suctions air, and generates and flow of the air,

wherein the blower casing unit (100) that prevents an increase in temperature of the impeller unit (200) by guiding air suctioned inside to a specific path includes;

a first air suction compartment (110) into which air suctioned by an impeller (230) flows;

a second air suction compartment (120) into which air suctioned by the impeller unit-cooling fan (240) flows;

a first air suction duct (130) that allows air to be suctioned into the first air suction compartment (110) by the impeller (230);

a first air discharge duct (140) that allows the air suctioned through the first air suction duct (130) to be compressed and discharged to a fuel cell stack by the impeller unit (200);

a second air suction duct (150) that allows air to be suctioned into the second air suction compartment (120) by the impeller unit-cooling fan (240);

a second air discharge duct (160) that allows the air, which has been suctioned through the second air suction duct (150) and has cooled the impeller unit (200), to be discharged;

a cooling air path (170) formed by the second air suction duct (150) and the second air discharge duct (160); and

an impeller unit-water cooler (180) formed adjacent to the impeller unit (200) disposed in the second air suction compartment (120) and having a cooling water inflow circulation groove (181) cooling the impeller unit (200) using the flow of cooling water supplied from the outside,

so efficiency and durability of the turbo blower for a fuel cell are maximized through a cooling method simultaneously using both of air cooling and water cooling by reducing an increase in temperature of the impeller unit (200) by cooling a portion of the impeller unit (200) rotating at high speed in the second air suction compartment (120) using the flow of air guided to a specific path,

wherein the impeller unit (200) allowing air to be suctioned into the first air suction compartment (110) and the second air suction compartment (120) includes;

a stator (210);

a rotor (220);

an impeller (230); and

the impeller unit-cooling fan (240) spaced in the opposite direction apart from an impeller (230) coupled to an end of a rotor (220), coupled to the other end of the rotor (220), disposed in the second air suction compartment (120), and suctioning air into the second air suction compartment (120), and

an increase in temperature of the impeller unit (200) that is rotated at high speed is reduced, and efficiency and durability are maximized.
