Blower motor flange diverter
View Patent ↗A blower motor assembly for use in a heating, ventilation and air-conditioning system of a vehicle and a method of diverting water are disclosed. The blower motor assembly may include a motor housing, configured to surround internal components of the blower motor assembly, and including a cooling channel/air intake opening. The blower motor assembly may also include a motor support flange extending radially outward from the motor housing and having an upward facing surface, and at least one water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape to divert water off of the flange.
1. A blower motor assembly for use in a heating, ventilation and air-conditioning system of a vehicle comprising:
a motor housing, configured to surround internal components of the blower motor assembly, and including a cooling-channel-and-air-intake opening;
a motor support flange extending radially outward from the motor housing and having an upwardly extending inverter flange contacting the motor housing and an upward facing surface extending radially outward from the inner vertical flange; and
a first water diversion vane extending upward from the upward facing surface and extending radially outward from the inner vertical flange in an arcuate shape, the first water diversion vane being adjacent to the cooling-channel-and-air-intake opening.
2. The blower motor assembly of claim 1 including a second water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape, the second water diversion vane being circumferentially spaced from the first water diversion vane.
3. The blower motor assembly of claim 2 including a third water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape, the third water diversion vane being circumferentially spaced from the first and second water diversion vanes.
4. The blower motor assembly of claim 3 including a fourth water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape, the fourth water diversion vane being circumferentially spaced from the first, second and third water diversion vanes.
5. The blower motor assembly of claim 1 wherein the first water diversion vane has a height above the upward facing surface of two millimeters.
6. The blower motor assembly of claim 1 wherein the first water diversion vane includes an opening surround portion extending around a radially inner portion of the cooling-channel-and-air-intake opening.
7. A heating, ventilation and air-conditioning system for use in a vehicle comprising:
a module housing having an air inlet opening configured to accept air flow from outside of the vehicle; and
a fan assembly including a blower motor assembly and a blower operatively engaging the blower motor assembly, the fan assembly located below the air inlet opening;
wherein the blower motor assembly includes a motor housing, a motor support flange extending radially outward from the motor housing and having an upward extending inner vertical flange contacting the motor housing and an upward facing surface extending radially outward from the inner vertical flange, and a first water diversion vane extending upward from the upward facing surface and extending radially outward from the inner vertical flange in an arcuate shape that curves in a direction of rotation of the blower as the first water diversion vane extends radially outward.
8. The heating, ventilation and air-conditioning system of claim 7 wherein the motor housing includes a cooling-channel-and-air-intake opening, the first water diversion vane being adjacent to and extending around a portion of the intake cooling-channel-and-air-intake opening.
9. The heating, ventilation and air-conditioning system of claim 8 wherein the first water diversion vane includes an opening surround portion extending around a radially inner portion of the cooling-channel-and-air-intake opening.
10. The heating, ventilation and air-conditioning system of claim 7 including a second water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape that curves in a direction of rotation of the blower as the second water diversion vane extends radially outward, the second water diversion vane being circumferentially spaced from the first water diversion vane.
11. The heating, ventilation and air-conditioning system of claim 10 including a third water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape that curves in a direction of rotation of the blower as the third water diversion vane extends radially outward, the third water diversion vane being circumferentially spaced from the first and second water diversion vanes.
12. The heating, ventilation and air-conditioning system of claim 11 including a fourth water diversion vane extending upward from the upward facing surface and extending radially outward in an arcuate shape that curves in a direction of rotation of the blower as the fourth water diversion vane extends radially outward, the fourth water diversion vane being circumferentially spaced from the first, second and third water diversion vanes.
13. The heating, ventilation and air-conditioning system of claim 7 wherein the first water diversion vane has a height above the upward facing surface of two millimeters.
