Tool-less apparatus and methods are provided for sealing flow of cooling air from the outlet of a cooling fan blower to the inlet of a heat exchanger within a chassis enclosure of an information handling system. The disclosed apparatus and methods may be implemented in a tool-less manner by employing tool-less chassis mounting features that mate with tool-less cooling fan mounting features to mechanically align and secure an air outlet of a cooling fan blower in sealing relationship with an air inlet of a heat exchanger within a chassis enclosure of an information handling system by properly aligning the axes of a cooling fan in relation to the inlet of the heat exchanger so that in on embodiment no gap exists between the cooling air outlet of the cooling fan and the cooing air inlet of the heat exchanger.

A transfer tube for a thermal transfer device can include at least one wall having an inner surface and an outer surface, where the inner surface forms a cavity, where the at least one wall further has a first end and a second end. The first end can be configured to couple to a terminus of a heat exchanger of the thermal transfer device. The second end can be configured to couple to a collector box of the thermal transfer device. At least a portion of the at least one wall can be disposed in a vestibule of the thermal transfer device. The cavity can be configured to simultaneously receive a first fluid that flows from the first end to the second end and a second fluid that flows from the second end to the first end.

Heat exchanger comprising at least a first plate (11) and at least a second plate (12) overlapping and reciprocally joined to each other in correspondence with respective coupling surfaces (13). Between the coupling surfaces (13), at least one passage channel (14) for a heat-carrying fluid is made, by deforming at least one of the two plates (11, 12).

A thermal management module for a thermal management system is disclosed. The thermal management module includes a first heat exchanger for flowing through by a refrigerant and by a working medium fluidically separately with respect to the refrigerant. A second heat exchanger is provided including at least a first fluid path and at least a second fluid path, separate from the first fluid path, respectively for flowing through by the refrigerant. A connecting arrangement is arranged between the first heat exchanger and the second heat exchanger. The connecting arrangement connects the first heat exchanger and the second heat exchanger to one another mechanically and fluidically, so that the refrigerant can flow between the first heat exchanger and the second heat exchanger.

A thermal bridge includes an upper bridge assembly including upper plates arranged in an upper plate stack and a lower bridge assembly including lower plates arranged in a lower plate stack. The thermal bridge includes upper spring elements extending from upper plates having upper mating interfaces engaging lower plates to bias the upper plates in a first biasing direction generally away from the lower bridge assembly. The thermal bridge includes lower spring elements extending from lower plates having lower mating interfaces engaging upper plates to bias the lower plates in a second biasing direction generally away from the upper bridge assembly. A bridge frame having connecting elements extends through the upper plates and the lower plates to hold the upper plates in the upper plate stack and to hold the lower plates in the lower plate stack.
