Filter inline heater

A filter assembly for filtering aqueous urea solution, the filter assembly comprising:

• a housing defining an interior region and exterior region, the interior region and the exterior region being in fluid communication with a first aperture and a second aperture, wherein the housing includes a first sub-housing and a second sub-housing releasably attached to each other by a fastener;
• a fluid filter received within the housing, the filter separating the housing into
• an upstream region upstream of the filter, the upstream region in fluid communicating with the second aperture, and
• a downstream region downstream of the filter, the downstream region in fluid communicating with the first aperture;
• a heater supported on the second sub-housing and extending into the interior region of the housing, wherein the heater is in thermal communication with at least the upstream region;
• a first hose fitting in fluid communicating with the first aperture;
• a second hose fitting in fluid communicating with the second aperture, wherein the first hose fitting and second hose fitting are supported on the second sub-housing;
• a heat bridge supported on the second sub-housing,
• formed of a conductive material having a thermal conductivity of at least 16 W/(m*K),
• thermally connecting the heater to the first hose fitting, and
• thermally connecting the heater to the second hose fitting;
• and
• a first insulator
• formed of a material having a thermal conductivity of at most 0.25 W/(m*K),
• the first insulator at least partially covering the first hose fitting;
• and
• a second insulator
• formed of a material having a thermal conductivity of at most 0.25 W/(m*K),
• the second insulator at least partially covering the second hose fitting.
