Inductor cooling systems and methods
Inductor cooling systems and methods are disclosed. A vehicle inductor cooling system, may include an inductor assembly, a flange extending around a periphery of the inductor assembly, an inductor cover having a sealing surface forming a seal with the flange, a cavity defined by the inductor cover and the inductor assembly, and a first opening defined in the inductor cover configured to provide coolant to the cavity. The flange may include a first recess defined therein that communicates with the first opening and is configured to receive coolant through the first opening and provide it to the cavity. A portion of the cover including the first opening may be configured to form a seal with a coolant inlet of a vehicle transmission case such that coolant is configured to flow through the coolant inlet, through the first opening, into the first recess, and into the cavity.
1. A vehicle inductor cooling system, comprising:
an inductor assembly;
a flange extending continuously around a mid-portion of the inductor assembly and including a first recess;
an inductor cover having a sealing surface forming a seal with the flange;
a cavity defined by the inductor cover and the inductor assembly; and
a first opening defined in the inductor cover in fluid communication with the first recess to provide coolant to the cavity.
2. The system of claim 1 , wherein a portion of the cover including the first opening is configured to form a seal with a coolant inlet of a vehicle transmission case such that coolant is configured to flow through the coolant inlet, through the first opening, into the first recess, and into the cavity.
3. The system of claim 1 , further comprising a second opening defined in the inductor cover configured to allow coolant to exit the cavity.
4. The system of claim 3 , wherein the flange includes a second recess defined therein that communicates with the second opening and is configured to receive coolant from the cavity and provide the coolant to the second opening.
5. The system of claim 4 , wherein a portion of the cover including the second opening is configured to form a seal with a coolant outlet of a vehicle transmission case such that coolant is configured to flow from the cavity, into the second recess, through the second opening, and into the coolant outlet.
6. The system of claim 1 , wherein the inductor assembly includes a core and a conductive coil wrapped around the core and a bottom portion of the coil extends into the cavity and is configured to be directly contacted by the coolant.
7. A vehicle, comprising:
a transmission case including a coolant inlet;
an inductor assembly;
a flange extending continuously around a mid-portion of the inductor assembly and including a first recess;
an inductor cover having a sealing surface forming a seal with the flange;
a cavity defined by the inductor cover and the inductor assembly; and
a first opening defined in the inductor cover in fluid communication with the first recess to provide coolant to the cavity from the coolant inlet.
8. The vehicle of claim 7 , wherein a portion of the cover including the first opening forms a seal with the coolant inlet such that coolant is configured to flow through the coolant inlet, through the first opening, into the first recess, and into the cavity.
9. The vehicle of claim 7 , further comprising a second opening defined in the inductor cover configured to allow coolant to exit the cavity, wherein the flange includes a second recess defined therein that communicates with the second opening and is configured to receive coolant from the cavity and provide the coolant to the second opening.
10. The vehicle of claim 9 , wherein a portion of the cover including the second opening forms a seal with a coolant outlet of the transmission case such that coolant is configured to flow from the cavity, into the second recess, through the second opening, and into the coolant outlet.
11. The vehicle of claim 7 , wherein the inductor assembly includes a core and a conductive coil wrapped around the core and a bottom portion of the coil extends into the cavity and is configured to be directly contacted by the coolant.
12. The vehicle of claim 7 , further comprising a first fastener portion connected to the flange that defines a first aperture configured to receive a fastener;
the transmission case including a second fastener portion defining a second aperture configured to receive a fastener; and
a fastener extending through the first and second apertures and securing the flange to the transmission case.
13. The vehicle of claim 12 , wherein the second fastener portion of the transmission case is integrally formed with the coolant inlet.
14. The vehicle of claim 12 , wherein the transmission case further comprises a coolant outlet and the second fastener portion of the transmission case is integrally formed with the coolant outlet.
15. A method, comprising:
introducing coolant into a cavity defined by a cover sealed around a flange extending continuously about a mid-portion of an inductor assembly;
directly contacting a coil of the inductor assembly with the coolant to remove heat therefrom; and
removing the coolant from the cavity,
wherein the coolant is introduced into the cavity through a coolant inlet integrally formed in a vehicle transmission case, an opening defined in the cover, and a recess defined in the flange, respectively.
16. The method of claim 15 , wherein during an operating state of the inductor assembly, coolant is continuously introduced into and removed from the cavity to continuously cool only a bottom portion of the coil of the inductor assembly to remove heat therefrom.
