## Abstract

A heat exchange module having a heat transfer fluid channel and a heat transfer plate in heat transfer relation with fluid in the channel. The reference side of a thermoelectric cooler (TEC) is in thermal contact with the plate. A heat transfer tile is in thermal contact with a user side of the TEC. The module is configured to be operatively positionable with the tile in heat transfer relation with skin of a patient.

## Claims

### Claim 1

A method of producing a soft good, wherein said soft good comprises an HEM, and wherein said soft good is produced to conform to a user's body type, said method comprising:
cutting a soft good to fit a certain design specification, wherein said design specification relates to a human body part;
welding an inner and outer layer of an air bladder;
welding an air tube to the air bladder;
joining the air bladder to an outer layer of a soft good, wherein said outer layer is related to said design specification;
joining an inner fabric of a soft good to said outer layer, wherein said inner layer is related to said design specification;
joining a zipper to the soft good; and
edge binding said soft good, wherein said edge binding encloses an HEM within said soft good.

### Claim 2 (depends on 1)

The method of claim 1, wherein said design specification is selected from a group consisting of a back, a knee, a shoulder, an ankle.
