A heat exchange module alone or part of a system including a control console. The HEM can include a channel enclosure assembly, a thermoelectric cooler (TEC) assembly and a heat transfer (cover) assembly. The enclosure assembly includes a channel for a heat-transfer liquid. The module can be constructed to provide for flexibility to better conform and fit on rounded and/or angular body parts and to efficiently transfer heat between the adjacent body part and the heat-transfer liquid via the TECs of the TEC assembly.

Heat exchange module, system and method

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.

A heat exchange module alone or part of a system including a control console. The module includes a channel assembly and a heat exchange stack attached thereto, and can be used to directly cool and/or heat tissue or skin. The channel assembly includes a liquid channel. The stack can include a pair of spaced plates with thermoelectric coolers exchangers, heat reflective layers, and a core composite layer which keeps the plates spaced. To provide flexibility of the module to better fit on round body parts the stack can include a thermally-conductive plate construction between the plates which has rotational flexibility axes in the X and/or Y directions between plate portions. Optionally the channel can include windows to which the plate portions are sealed. The heat exchange stack separately or together with the channel assembly can be secured in the thickness direction with mechanical securements such as sewing or tacking to also provide for greater flexibility.

Heat exchange module and system for medical applications

A heat exchanger module (HEM) and system uses a flexible substrate with one or more open channels, to which a substrate cover is bonded, thereby forming closed channels in the flexible substrate. Thermoelectric coolers (TECs) are attached to optional thermally diffusing copper squares atop the substrate cover. An interface cover is attached to the TEC tops, with a compliant thermally conductive material opposite the TECs and ultimately in contact with a patient. A liquid is passed through the closed channels, which act as thermal references for the TECs. Current is supplied by a controller to the TECs to induce TEC cooling or heating relative to the liquid. One or more temperature sensors detect the temperature of the interface cover, which are used as inputs to the control of the TEC supply current. The HEM may be used for heating, cooling, or cycling between heating and cooling for various medical uses.

Thermoelectric temperature controlled cooler for biomedical applications

A method for reinforcing joints between one or more components is presented. Adhesive is applied to joint areas of contact between the components and the components are stitched together at the joint areas to ensure that the joints are mechanically stable enough to withstand stresses such as pressurization and external manipulation.
