A system includes a matrix material to remove heat from an object. The matrix material includes a plurality of vascular structures. Each of the vascular structures are filled with a fluid. At least one transducer generates field-induced forces into the fluid within the vascular structures of the matrix material. At least one controller pulses the transducer to generate the field-induced forces into the fluid within the vascular structures. The field-induced forces generate fluid flow within the vascular structures to remove the heat from the object.

A heat exchanger includes a plurality of principal heat exchange sections and auxiliary heat exchange sections. Each of the auxiliary heat exchange sections is in series connection to a corresponding one of the principal heat exchange sections. Tube number ratios of the principal heat exchange sections are obtained by dividing the number of the flat tubes constituting each of the principal heat exchange sections by the number of the flat tubes constituting a corresponding one of the auxiliary heat exchange sections. Of the principal heat exchange sections, the first principal heat exchange section, which is the lowermost one, has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section is accelerated during defrosting, thereby shortening the time required for defrosting.

A cooling device includes: a heat receiver configured to transfer heat from a heat generation body to a refrigerant, a heat radiator that is connected to the heat receiver via a heat radiation path, and a return path that connects the heat radiator and the heat receiver with each other, in which the refrigerant is to circulate in order of the heat receiver, the heat radiation path, the heat radiator, and the return path and cause a gas-liquid two-phase change and cool the heat generation body, and in which the heat receiver includes a heat receiving plate which is in contact with the heat generation body and is configured to absorb the heat, and a heat receiving cover which covers a surface of the heat receiving plate and defines a heat receiving space.

Capillary trap-vapor pumps, systems, methods of heat management, and the like, are disclosed.

An assembly for liquid cooling is provided herein. The assembly 8 includes a thermal member, a support member, and a gasket. The thermal member includes an array of cooling pins formed of a thermally conductive material to extend from the thermal member. The support member includes an inlet channel and an outlet channel. The inlet channel to provide a fluid to the array of cooling pins. The outlet channel to receive the fluid from the array of cooling pins. The gasket between the thermal member and the support member to form a cooling channel with a fluid tight seal therebetween.

A heat exchanger (1) for tempering of an object (7), in particular of an electric energy reservoir (8), has two components (2, 3), which are interconnected and delimit at least in part a flow compartment (17) for the flow of a tempering fluid. Furthermore, at least one of the components (2, 3) is produced from a composite fiber plastic. Improved handling and/or a more compact design is obtained in that at least one of the components (2, 3) has a depression (9) in which a functional element can be at least partially accommodated.

A canister system having a cylindrical housing and a modular electronic rack system disposed within the cylindrical housing. The modular electronic rack system includes a thermal contact member that is in at least selective physical contact with an interior surface of the cylindrical housing to permit conductive heat transfer there through. An input/output device extends along at least a portion of the modular electronic rack system and includes a power input and a signal output electrically coupled thereto. A plurality of electronic slots disposed at a position generally along the modular electronic rack system is provided.

In one aspect, a device with dynamic optical properties comprises a fluid transfer component comprising a polymer film with one or more layers; an active region of the fluid transfer component comprising a plurality of fluid channels defined by one or more interior surfaces within the polymeric film. In one embodiment, each fluid channel comprises at least 1 row of fluid channels in a thickness direction of the polymeric film. Each fluid channel comprises a first fluid with a first optical property and the active region has a first optical state, and when the a flow source generates fluid flow for a second fluid with a second optical property different from the first optical property to flow through the fluid channels in the active region, the optical state of the active region changes from a first optical state to a second optical state different from the first optical state.
