摘要： A heatsink comprising a heat exchange device having a plurality of heat exchange elements each having a surface boundary with respect to a heat transfer fluid, having successive elements or regions having varying size scales. According to one embodiment, an accumulation of dust or particles on a surface of the heatsink is reduced by a removal mechanism. The mechanism can be thermal pyrolysis, vibration, blowing, etc. In the case of vibration, adverse effects on the system to be cooled may be minimized by an active or passive vibration suppression system.

摘要： Provided is a positive temperature coefficient (PTC) unit for a vehicle heater. The PTC unit according to an exemplary embodiment of the present invention includes: a heat generation part which includes PTC elements; and a heat radiation part which is provided on at least one surface of the heat generation part and includes a heat radiation base material and a heat radiation film provided on at least a portion of an outer surface of the heat radiation base material to improve heat radiation performance. According to the present invention, improved heat radiation performance may be exhibited, and concurrently, heat radiation performance due to excellent durability may be exhibited for a long period of time without a structural change for increasing a specific surface area of a heat radiation part while reducing an air ventilation property, so as to improve heat radiation performance. In addition, since an air ventilation property of the heat radiation part is increased, it is possible to prevent increases in noise and power consumption due to excessive use of peripheral devices such as a fan. Furthermore, since it is possible to prevent overheating of a PTC module and overload of a PTC module control circuit, which are caused by a reduction in the air ventilation property of the heat radiation part, a high-priced and high performance control circuit may not be required, thereby implementing a PTC heater for a vehicle with reduced production costs.

摘要： A cyclone heat-dissipation fin assembly includes a heat pipe and first and second arc-shaped heat-dissipation fin groups fixed thereon. The first and second arc-shaped heat-dissipation fin groups are in snap fit with each other along a vertical direction, and are configured to open in opposite directions. Each fin group includes at least one heat-dissipation fin stackedly arranged. A fan with multiple rotating blades is provided at a side of the heat-dissipation fin groups to generate a swirling airflow to the arc-shaped heat-dissipation fin.

摘要： A brazed plate heat exchanger (10) comprising a stack of heat exchanger plates (12a, 12b) provided with a pattern comprising ridges (R) and grooves (G) to form plate interspaces (13a, 13b) for fluids to exchange heat. The heat exchanger plates are provided with port openings (O1-O4) forming inlet and outlet channels (14) for the first and second fluids, wherein at least one of the first and second heat exchanger plates is arranged with a skirt to form a chamber (17) between the port opening and the plate interspaces. The chamber (17) is open to the channel (14) through a gap between at least a free end portion of the skirt and the adjacent heat exchanger plate, and the gap varies around the circumference of the channel (14) and/or a cross section area of the chamber (17) varies around the circumference of the channel (14).

摘要： Rocket components having internal heat fins are described herein. The disclosed components have internal heat fins that mitigate buckling and uneven force application by adding thermal capacity to the component without adding component stiffness. This reduces a thermal force fight (i.e., tension versus compression between cold and hot areas, respectively), which inhibits the buckling loads on the propellant tank. The internal heats fins also provide for a reduced mass of the propellant tank wall relative to a propellant tank wall without internal heat fins. By reducing the thermal force fight, as discussed above, less material can be used which further allows for thinner welds to be used (i.e., less welding material).

摘要： A gas treatment component comprises a cross-flow heat exchanger and a counter-flow heat exchanger arranged in series with the cross-flow heat exchanger. The cross-flow heat exchanger and the counter-flow heat exchanger each comprise a core comprising a stack of heat exchanger plates, wherein the heat exchanger plates of the cross-flow heat exchanger form first channels for a first gas flow passing the cross-flow heat exchanger and form second channels for a second gas flow passing the cross-flow heat exchanger. A first distance between neighbouring heat exchanger plates forming the first channels is smaller than a second distance between neighbouring heat exchanger pates forming the second channels.

摘要： A battery cooling plate includes at least one planar heat transfer surface that is bounded by four edges. A coolant inlet port and a coolant outlet port are both arranged along a first one of the edges, and a coolant flow path extends through the battery cooling plate adjacent to the at least one planar heat transfer surface between the coolant inlet port and the coolant outlet port. The coolant flow path includes a first portion that extends along the entire length of a second, third, and fourth edge of the at least one planar heat transfer surface. The coolant flow path further includes a second portion that is arranged downstream of the first portion. The second portion of the coolant flow path is separated from the second, third, and fourth edges of the planar heat transfer surface by the first portion of the coolant flow path.
