摘要： An improved indirect heat exchanger is provided which is comprised of a plurality of coil circuits, with each coil circuit comprised of an indirect heat exchange section tube run or plate. Each tube run or plate has at least one change in its geometric shape or may have a progressive change in its geometric shape proceeding from the inlet to the outlet of the circuit. The change in geometric shape along the circuit length allows simultaneously balancing of the external airflow, internal heat transfer coefficients, internal fluid side pressure drop, cross sectional area and heat transfer surface area to optimize heat transfer.

摘要： Electrochemical cell battery system and associated methods of operation are provided based on the incorporation of a thermal suppression construct including a supply of cooling fluid dispensed in intimate contact with the cells disposed within an enveloping sealed enclosure. The electrochemical cells are connected electrically by bus bars to form a battery of cells. The bus bars support cooling by convection methods. The cells are allowed to float mechanically as they are charged and discharged while maintaining intimate thermal contact with the enveloping sealed enclosure through conduction and the bus bars through conduction. The system provides a method of cooling the cells by conduction and convection and that accommodates mechanical changes to both the cells and the enveloping sealed enclosure.

摘要： A heat exchanger includes a flow channel operatively connecting a channel inlet to a channel outlet to channel fluid to flow therethrough. The flow channel is defined at least partially by a shape change material. The shape change material changes the shape of the flow channel based on the temperature of the shape change material. The shape change material can include a shape-memory alloy, for example. The shape-memory alloy can include at least one of a nickel-titanium alloy (NiTi), Cu—Al—(X), Cu—Sn, Cu—Zn—(X), In—Ti, Ni—Al, Fe—Pt, Mn—Cu, or Fe—Mn—Si.

摘要： A heat pipe comprises a tube and protrusions. The tube has an internal surface, an external surface, and a length running from a first end to a second end. The protrusions are on the internal surface. A first cross-section of the protrusions at a first location of the length of the tube is different from a second cross-section of the protrusions at a second location of the length of the tube. The tube and the protrusions are monolithic.

摘要： Materials, components, and methods consistent with the disclosure are directed to the fabrication and use of micro scale channels with a gas, where the micro channel can include a base (110) and a side (120), where the base and the side can be configured to form at least a portion of an inflow opening, and an outflow opening. The micro channel can be configured to accommodate a flow of the gas from the inflow opening to the outflow opening in a first direction substantially perpendicular to a cross section of the micro channel. The side can have a thickness in a range 0.5 μm and 500 μm, where the micro channel with a thickness in a range 0.5 μm and 500 μm is formed, in part, by providing the side on the base.

摘要： A heat dissipating apparatus has a phase change material evaporator, a condenser, a refrigerant output tube, and a refrigerant input tube. The evaporator has a base having an evaporation chamber, a refrigerant inlet and a refrigerant outlet, a reinforcement panel mounted in the evaporation chamber and dividing the evaporation chamber into two spaces, and multiple heat conduction fins separately arranged in the two spaces. An opening area of the refrigerant outlet is larger than an opening area of the refrigerant inlet. The evaporator, the refrigerant output tube, the condenser and the refrigerant input tube form a closed refrigerant circulation loop with a refrigerant filled therein. Gas pressure of a gas-phased refrigerant in the two spaces can be increased. With pressure difference between the refrigerant outlet and the refrigerant inlet, the gas-phased refrigerant can be accelerated to flow toward the refrigerant outlet and flowability of the refrigerant can be increased.

摘要： A heat pump has an evaporator for evaporating water as a working liquid so as to produce a working vapor, the evaporation taking place at an evaporation pressure of less than 20 hPa. The working vapor is compressed to a working pressure of at least 25 hPa by a dynamic-type compressor so as to then be liquefied within a liquefier by direct contact with liquefier water. The heat pump is preferably an open system, wherein water present in the environment in the form of ground water, sea water, river water, lake water or brine is evaporated, and wherein water which has been liquefied again is fed to the evaporator, to the soil or to a water treatment plant.

摘要： A plate-fin condenser includes a plate body defining an interior channel having a fluid inlet, a first interior channel section having a first cross-sectional area in fluid communication with the inlet, a second interior channel section downstream of the first interior channel section, and a fluid outlet in fluid communication with the converging interior channel. The second interior channel section has a second cross-sectional area that is smaller than the first cross-sectional area.

摘要： A condenser having passages of varying geometry for cooling of fluid. The condenser apparatus includes substantially parallel tubes each defining a channel and having an inlet at a first end and an outlet at a second end, the first end having a greater hydraulic diameter than the second end. Inlet and outlet manifolds are provided. The tubes may be oriented substantially vertically with the inlets above the respective outlets. A heat exchanger core comprises the tubes and substantially horizontally oriented fin material connecting the tubes. The tubes may receive a relatively higher temperature vapor or vapor and liquid mixture into the inlets of the tubes, around the tubes coolant flows substantially horizontally to remove heat from the tubes, and relatively cooler saturated liquid is discharged from the outlets. In one embodiment, the tube's channel splits into multiple channels to reduce the hydraulic diameter and increase the surface area ratio.
