Abstract

A filter cooling construction includes a mass of filtration material held in a filter body and a cooling member extending in the mass of filtration material. A manifold communicates with the cooling member for channeling a cooling fluid to the cooling member. In another embodiment, a heat transfer construction is provided so that a temperature control fluid can flow to the heat transfer member thereby selectively heating and cooling the mass of filtration material. Once use for such constructions is in air filters.

Claims (32)

1 . A filter cooling construction comprising:

mass of filtration material held in a filter body;

a cooling member extending in said mass of filtration material; and, a manifold communicating with said cooling member for channeling a cooling fluid to said cooling member.

2 . The construction of claim 1 wherein said cooling member comprises a fin.

3 . The construction of claim 2 wherein said fin is oriented approximately transverse to a direction of a fluid to be treated as it flows through said mass of filtration material.

4 . The construction of claim 2 wherein said fin comprises a plurality of channels through which the cooling fluid flows.

5 . The construction of claim 1 wherein said filter body has an annular shape including an outer wall and an inner wall, said mass of filtration material being disposed therebetween.

6 . The construction of claim 5 wherein a plurality of fin-like cooling members are disposed in a spaced manner in said filter body, said manifold communicating with each of said cooling members.

7 . The construction of claim 1 further comprising a pump communicating with said manifold for pressurizing the cooling fluid.

8 . The construction of claim 7 further comprising a control module in communication with said manifold and said pump for controlling an operation of said pump.

9 . The construction of claim 8 further comprising a heat condenser and at least one fluid line which communicates said manifold and said pump with said heat condenser.

10 . The construction of claim 1 wherein said cooling member comprises a plurality of channels through which the cooling fluid flows.

11 . A heat transfer construction for an air filter comprising:

a mass of filtration material held in a filter housing;

a heat transfer member extending in said mass of filtration material; and

a manifold communicating with said heat transfer member for channeling a temperature control fluid to said heat transfer member, thereby selectively heating and cooling said mass of filtration material.

12 . The construction of claim 11 wherein said heat transfer member comprises a fin.

13 . The construction of claim 11 wherein said heat transfer member is oriented approximately transverse to a direction of airflow through said mass of filtration material.

14 . The construction of claim 11 wherein said heat transfer member comprises a plurality of channels through which the temperature control fluid flows.

15 . A heat transfer system for an air filter, comprising:

a filter body including a wall and a filtration material held within said wall;

a heat transfer member extending in said filtration material, said heat transfer member comprising at least one channel through which a temperature control fluid flows; and

a manifold communicating with said heat transfer member at least one channel for directing the temperature control fluid toward and away from the heat transfer member.

16 . The system of claim 15 wherein said heat transfer member is relatively wide and relatively thin in order to minimize a resistance to airflow through said filter body while increasing a heat transfer area with said filtration material.

17 . The system of claim 15 wherein said heat transfer member is oriented approximately transverse to a direction of airflow through said filtration material in order to minimize a resistance to airflow.

18 . The system of claim 15 further comprising:

a pump communicating with said manifold for pressurizing the temperature control fluid; and,

a control module in communication with said manifold and said pump for controlling an operation of said pump.

19 . The system of claim 18 further comprising:

a heat condenser; and

at least one fluid line which communicates said manifold, said heat condenser and said pump.

20 . The system of claim 15 wherein a plurality of heat transfer members extends in said filtration material in a manner spaced from each other, said plurality of heat transfer members being so oriented in relation to a direction of airflow through said filter so as to minimize a resistance to airflow.
