    摘要： System and method for cooling of an integrated circuit utilizing Micro-Electro Mechanical Systems (MEMS) components. A flexible thin film has an upper flexible substrate, a lower inflexible substrate and flexible seals. One face of the lower substrate is in contact with at least one hot medium and the other face is in contact with a coolant fluid. One face of the upper substrate is in contact with the coolant fluid and the other face is in contact with the surrounding ambient. Two continuous flexible seals are attached to the faces of the upper lower substrates to form at least one closed enclosure comprising a thermally conducting gas. The thermally conducting gas is in direct contact with the lower substrate. The upper substrate deflects continuously and maximally in the direction along the coolant fluid flow direction when the flexible seals deflect when the thermally conducting gas undergoes volumetric thermal expansion.

    摘要： A DL-microchannel cooling device with rotatable separating plate is disclosed. The separating plate is supported via anti-leaking flexible seals. The only allowable motion for that plate is the rotational motion about a pivot rod. The rod is taken to be aligned along the microchannel center line normal to its sides boundaries. The device can be configured as a flexible microheat exchanger and a heated DL-flexible microchannel device. The theory of linear elasticity applied to flexible seals supporting the separating plate is used to relate the moment of the pressure forces on that plate to its rotational angle. The energy equations for both fluids flows are solved numerically and analytically under special conditions. As such, the effectiveness of the flexible microheat exchanger and other performance indicators for flexible microheat exchanger and heated DL-flexible microchannel devices are calculated. The advantages of the proposed device in cooling attributes over the performance of the DL-rigid microchannel device is examined.

    摘要： An assembly of microcantilever-based sensors with enhanced deflections. A deflection profile of an ε-assembly can be compared with that of a rectangular microcantilever and a modified triangular microcantilever. Various force-loading conditions can also be considered. A theorem of linear elasticity for thin beams is utilized to obtain the deflections. The obtained defections can be validated against an accurate numerical solution utilizing a finite element method with a maximum deviation of less than 10 percent. The ε-assembly produces larger deflections than the rectangular microcantilever under the same base surface stress and same extension length. Also, the ε-microcantilever assembly produces a larger deflection than a modified triangular microcantilever. The deflection enhancement increases as the ε-assembly's free length decreases for various types of force loading conditions. The ε-microcantilever can be utilized in microsensing applications to provide a favorable high detection capability with a reduced susceptibility to external noises.

    摘要： Devices for the control of flow rate and thermal conditions using two-layered thin films separated by flexible complex seals. The plates of an upper thin film are separated by a sealing assembly. The sealing assembly is composed of an elastic soft seal separating closed voids of stagnant fluid and in contact with the upper plate of the device as it is the heated plate. The lower and the upper plates of the lower thin film can be separated by an elastic soft seal. The lower and upper thin films are named as main and secondary layers, respectively. Both the upper plate of the secondary layer and the lower plate of the main layer are fixed while the intermediate plate and is free to move in the vertical direction. When the pressure or the working temperature in the secondary layer increases, the secondary layer expands causing the main layer thickness to shrink. This reduces the main layer flow rate and temperature gradients within the main layer.
