A tubular structure including an outer tube an inner tube arranged within the outer tube and at least one chamber formed between the outer tube and the inner tube. The tubular structure additionally includes at least one self-healing material arranged in the chamber, wherein the self-healing material is configured to solidify and/or expand upon contact with a reacting material.

A self-healing metal structure is provided for transferring heat between an electronics component and a substrate. The self-healing metal structure includes a base metal structural component. A phase change material is provided adjacent at least a portion of the base metal structural component. A protective component at least partially encapsulates the phase change material. Upon the presence of a spatial defect in the base metal structural component, the phase change material reacts with the base structural component to form an intermetallic compound to at least partially occupy the spatial defect. The phase change material at least partially encapsulated with the protective component may be disposed within the base metal structural component as a plurality of separate capsules incorporated therein, or the phase change material at least partially surrounds the base metal structural component.

An endplate of a battery module is configured with holes through which an inlet and outlet for a cooling tube are arranged. Cooling interfaces between the inlet and outlet and a cooling manifold are arranged outside of a battery module compartment that houses the battery module. In a first embodiment, sealing components separate from the cooling tube are arranged inside the inlet and outlet holes, with each sealing component defining multiple sealing areas (e.g., ring-shaped sealing areas) for sealing a respective hole. In a second embodiment, the cooling tube includes integrated sealing components (e.g., threaded sections of the cooling tube) inside the inlet and outlet holes, with each integrated sealing component defining a single sealing area (e.g., a ring-shaped sealing area) for sealing a respective hole.

A heat exchanger includes a drain assembly having a housing and a drain plug. The drain plug is movably disposed within the housing to extend along the same direction as a drain passage formed in the housing. The drain plug is movable along that same direction to selectively open or close the drain passage. Accordingly, the heat exchanger may be drained with a controllable directional flow.

A shrinking device and a liquid cooling system are provided. The shrinking device includes a housing, and a shrinking bag at least partially inserted into the housing. The shrinking bag is in communication with the outside atmosphere through a vent hole. The shrinking device according to the present invention can solve the liquid leakage problem caused by excessive pressure inside the system.

A heat exchanger is disclosed. The heat exchanger includes a heat exchange member that includes a first extruded member having a first end and a second end. The first extruded member forms a plurality of fluid passages that are in fluid communication with the first end of the first extruded member and the second end of the first extruded member. At least one of the fluid passages is an inlet fluid passage and at least one of the fluid passages is an outlet fluid passage. A plug is fixedly coupled to the second end of the first extruded member. The plug forms a plug fluid passage that fluidically interconnects the inlet fluid passage at the second end of the first extruded member with the outlet fluid passage at the second end of the first extruded member.
