Engine coolant thermostat housing
A casted thermostatic housing for an engine coolant system. The housing has a plurality of exterior heat dissipating projections. An interior post for contacting a thermostatic element is circular and preferably tapered. The housing is casted metal and is preferably aluminum.
1. A casted metallic thermostatic housing for an internal-combustion engine coolant system, the thermostatic housing comprising:
a unitary body having:
a first body portion that has an open interior surrounded by a flange, configured for mounting the first body portion to an existing engine, and dependent thermostatic element holders;
a second dome shaped body portion that overlies the first body portion and defines an interior cavity over the open interior of the first body portion, the second dome shaped body portion has a conically tapered dependent post of a predetermined length that tapers toward the first body portion along the predetermined length; and,
a third body portion that is in fluid communication with the second dome shaped body portion and defines a coolant transport conduit wherein the dependent post has a free end and the free end has a recess that receives a stem associated with a thermostatic element.
2. The thermostatic housing of claim 1 , wherein the housing has a plurality of heat dissipating projections.
3. The thermostatic housing of claim 2 , wherein the plurality of heat dissipating projections are distributed about an external surface of the housing.
4. The thermostatic housing of claim 1 , wherein the thermostatic housing is casted aluminum.
5. A unitary casted metallic housing for assembling a thermostat to an internal combustion engine, the unitary casted metallic housing comprising:
a first body portion configured for supporting a thermostatic element, a second dome shaped body portion configured for mounting the first body portion on an engine, and a third body portion that is in fluid communication with the second body portion and defines a conduit for transporting coolant to a radiator,
wherein the second dome shaped body portion of the housing includes a plurality of external heat dissipating projections and an internal dependent post with a circular cross-section and a recess for receiving a portion of a thermostatic element.
6. A thermostatic housing for an internal-combustion engine coolant system, the thermostatic housing comprising:
a first body portion that has an open interior surrounded by a flange configured for mounting the first body portion to an existing engine;
a second dome shaped body portion that overlies the first body portion and supports an integral post that extends toward the first body portion and includes a free end having a recess for receiving a portion of a thermostatic element; and,
a third body portion that is in fluid communication with the second dome shaped body portion and defines a coolant transport conduit wherein the dependent post has a free end and the free end has a recess that receives a stem associated with a thermostatic element.
