APPARATUS AND METHOD FOR PREVENTING A RELAY FROM FREEZING
In at least one embodiment, an apparatus including a relay is provided. The relay includes a coil, a terminal, and a thermal conductive material. The coil generates heat in response to a current. The terminal includes a first contact positioned thereon. The coil and the terminal define a cavity there between. The thermal conductive material is positioned in the cavity and is in thermal communication with the coil and the first contact to transfer heat from the coil to the first contact.
1 . An apparatus comprising:
a relay including:
a coil that generates heat in response to a current;
a terminal including a first contact positioned thereon, wherein the coil and the terminal define a cavity there between; and
a thermal conductive material being positioned in the cavity and being in thermal communication with the coil and the first contact to transfer the heat from the coil to the contact.
2 . The apparatus of claim 1 wherein the relay is configured to be positioned in a vehicle.
3 . The apparatus of claim 1 wherein the relay further includes a housing to receive the coil, at least a portion of the terminal, the first contact, and the thermal conductive material.
4 . The apparatus of claim 1 wherein the thermal conductive material directly contacts the coil.
5 . The apparatus of claim 4 wherein the thermal conductive material directly contacts the terminal to transfer the heat from the coil to the first contact.
6 . The apparatus of claim 1 wherein the thermal conductive material comprises one of a grease based material and a polymer including fillers of one of ceramic and graphite particles.
7 . An apparatus comprising:
a relay including:
a coil that generates heat in response to a current;
a first terminal including a first contact positioned thereon, wherein the coil and the first terminal define a cavity there between;
a second terminal includes a second contact positioned thereon, and
a thermal conductive material being positioned in the cavity and being in thermal communication with the coil and at least one of the first contact and the second contact to transfer the heat from the coil to the at least one of the first contact and the second contact and to prevent water from condensing on the least one of the first contact and the second contact.
8 . The apparatus of claim 7 wherein the relay is configured to be positioned in a vehicle.
9 . The apparatus of claim 7 wherein relay further includes a housing to receive the coil, at least a portion of the first terminal, the first contact, and the thermal conductive material.
10 . The apparatus of claim 7 wherein the thermal conductive material directly contacts the coil.
11 . The apparatus of claim 10 wherein the thermal conductive material directly contacts the first terminal to transfer the heat from the coil to the first contact.
12 . The apparatus of claim 7 wherein the thermal conductive material comprises one of a grease based material and a polymer including fillers of one of ceramic and graphite particles.
13 . A method for comprising:
activating a coil in a relay to generate heat from the coil;
thermally conducting the heat from the coil with a thermal conductive material;
transferring the heat from the thermal conductive material to a first terminal; and
transferring the heat from the first terminal to a first contact.
14 . The method of claim 13 further comprising positioning the relay in a vehicle.
15 . The method of claim 13 further comprising receiving, at a housing of the relay, at least a portion of the first terminal, the first contact and the thermal conductive material.
16 . The method of claim 13 further comprising directly contacting the thermal conductive material with the coil prior to thermally conducting the heat from the coil with the thermal conductive material.
17 . The method of claim 16 further comprising directly contacting the thermal conductive material to the first terminal prior to transferring the heat from the thermal conductive material to the first terminal.
