Abstract

A heat exchange system includes a housing, a cover, and a sealing mechanism. The housing includes an outer side, an inner side opposite the outer side, a supply channel on the inner side, an exit channel on the inner side, and a plurality of fins on the inner side. The plurality of fins define a plurality of transverse channels. Each transverse provides fluid communication between the supply channel and the exit channel. The cover covers the inner side of the housing. The sealing mechanism compresses the cover and the housing such that a seal is formed between the cover and the housing.

First claim

What is claimed is:

1 . A heat exchange system, comprising:
a housing including:
an outer side;
an inner side opposite the outer side;
a supply channel on the inner side and defined by a first wall extending from the inner side, the supply channel extending in a longitudinal direction of the housing;
an exit channel on the inner side and defined by a second wall extending from the inner side; and
a plurality of fins extending from the inner side, the plurality of fins defining a plurality of transverse channels, each transverse channel of the plurality of transverse channels providing fluid communication between the supply channel and the exit channel;
a cover covering the inner side of the housing; and a sealing mechanism including a plate and a plurality of fasteners configured to compress the cover and the housing such that a seal is formed between the cover and the housing, wherein a plate has the same shape as the cover, wherein the plurality of fasteners pass through the housing, the plate, and the cover, and wherein the cover comprises a supply path having a first portion extending in the longitudinal direction and a second portion extending at an angle relative to the longitudinal direction and toward the supply channel.

2 . The heat exchange system of claim 1 ,
wherein the housing includes a first end and a second end opposite the first end, wherein the plurality of fins includes a first fin adjacent a second fin, and a third fin adjacent the second fin, wherein the first fin and the second fin are closer to the first end than the third fin, and wherein a distance between the first fin and the second fin is smaller than a distance between the second fin and the third fin.

3 . The heat exchange system of claim 2 ,
wherein the distance between the first fin and the second fin defines a first transverse channel of the plurality of transverse channels, and wherein the distance between the second fin and the third fin defines a second transverse channel of the plurality of transverse channels.

4 . The heat exchange system of claim 3 , wherein the second transverse channel is wider than the first transverse channel.

5 . The heat exchange system of claim 1 ,
wherein the plurality of fins includes a first section of fins and a second section of fins, wherein a distance between adjacent fins of the first section of fins is different from a distance between adjacent fins of the second section of fins.

6 . The heat exchange system of claim 5 ,
wherein the distance between adjacent fins of the first section of fins is smaller than the distance between adjacent fins of the second section of fins.

7 . The heat exchange system of claim 6 ,
wherein the housing includes a first end and a second end opposite the first end, and wherein the first section of fins is closer to the first end of the housing than the second section of fins.

8 . The heat exchange system of claim 5 ,
where the plurality of fins includes a third section of fins, wherein a distance between adjacent fins of the third section of fins is different from the distance between adjacent fins of the first section of fins, and wherein a distance between adjacent fins of the third section of fins is different from the distance between adjacent fins of the second section of fins.

9 . The heat exchange system of claim 8 , wherein the second section of fins is between the first section of fins and the third section of fins.

10 . The heat exchange system of claim 9 ,
wherein the distance between adjacent fins of the first section of fins is smaller than the distance between adjacent fins of the second section of fins, and wherein the distance between adjacent fins of the second section of fins is smaller than the distance between adjacent fins of the third section of fins.

11 . The heat exchange system of claim 1 ,
wherein the supply path opens into the supply channel at a first end of the housing.

12 . The heat exchange system of claim 11 ,
wherein the exit channel extends in the longitudinal direction of the housing, wherein the cover comprises an exit path having a first portion extending in the longitudinal direction and a second portion extending at an angle relative to the longitudinal direction and toward the exit channel, and wherein the exit channel opens into the exit path at the first end of the housing.

13 . The heat exchange system of claim 1 ,
wherein the plurality of fasteners compresses the plate against the cover and compresses the cover against the housing.

14 . The heat exchange system of claim 13 , wherein the sealing mechanism comprises a gasket between the cover and the housing.

15 . The heat exchange system of claim 13 , wherein the plurality of fasteners are disposed along the perimeter of the plate and pass through the cover and the housing.

16 . The heat exchange system of claim 1 , wherein the supply channel, the exit channel, and the plurality of fins are coated with a parylene.

17 . The heat exchange system of claim 1 , wherein the cover is made of a material selected from the group consisting of polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), high-density polyethylene (HDPE), polyether ether ketone (PEEK), or combinations thereof.

18 . The heat exchange system of claim 1 , wherein the plurality of fins extend seamlessly from the inner side of the housing.

19 . The heat exchange system of claim 1 ,
wherein each fin of the plurality of fins has an end at the inner side, wherein the first wall has an end at the inner side and the second wall has an end at the inner side, and wherein the end of each fin is coplanar with the end of the first wall, and wherein the end of each fin is coplanar with the end of the second wall.

20 . The heat exchange system of claim 19 ,
wherein each fin has an opposite end opposite to the end of each fin at the inner side, wherein the first wall has an opposite end opposite to the end of the first wall at the inner side, wherein the second wall has an opposite end opposite to the end of the second wall at the inner side, and wherein the opposite end of each fin is coplanar with the opposite end of the first wall and coplanar with the opposite end of the second wall.

21 . The heat exchange system of claim 1 ,
wherein each fin of the plurality of fins has a length extending from the supply channel to the exit channel along the inner side, a height extending away from the inner side and perpendicular to the length, and a width extending along the inner side and perpendicular to the height and to the length, wherein the first wall has an interior surface facing the width of each fin at the supply channel, and wherein the second wall has an interior surface facing the width of each fin at the exit channel.

22 . A method of cleaning a heat exchange system, the heat exchange system including:
a housing including:
an outer side;
an inner side opposite the outer side;
a supply channel on the inner side and defined by a first wall extending from the inner side, the supply channel extending in a longitudinal direction of the housing;
