20210156619 | WICK STRUCTURES AND HEAT PIPE NETWORKS - A wick structure for a heat pipe network, the wick structure comprising multiple channels defined by wall portions protruding from a first surface of the wick structure and extending in an axial direction along a length of the wick structure, wherein at least one of the wall portions comprises a tapered termination. | 2021-05-27 |
20210156620 | HEAT DISSIPATING APPARATUS USING PHASE CHANGE HEAT TRANSFER - A heat dissipating apparatus using phase change heat transfer includes a box, a heat conductive block, a working fluid, and a heat transfer device. The box has a first shell plate and a second plate between both of which a chamber is defined. An opening is formed through the first shell plate. The heat conductive block is disposed corresponding to the opening; a portion of the heat conductive block is formed inside the chamber and the other portion of the heat conductive block is exposed out of the first shell plate. The working fluid is disposed in the chamber and in contact with the heat conductive block. The heat transfer device has an evaporator section installed inside the chamber to absorb the heat generated by the working fluid after phase change. Thus, the heat dissipating efficiency of the whole apparatus can be enhanced. | 2021-05-27 |
20210156621 | HEAT STORAGE TANK OPTIMISED USING CALCIUM CARBONATE PARTICLES - Provided is a heat storage tank including at least one chemically inert solid heat storage material containing at least calcium carbonate particles, in which the calcium carbonate particles have a size distribution with a diameter d50 of from 0.5 mm to 200 mm. | 2021-05-27 |
20210156622 | MICROCHANNEL FLAT TUBE AND MICROCHANNEL HEAT EXCHANGER - The present application discloses a microchannel flat tube and a microchannel heat exchanger. The microchannel flat tube includes a flat tube body and a row of channels. The row of channels is arranged in the flat tube body along a width direction. The row of channels extends through the flat tube body along a length direction. A cross-section of each channel includes a first width in the width direction and a first height in a thickness direction. The row of channels at least includes a first channel, a second channel and a third channel along the width direction. The first widths of the first channel, the second channel and the third channel are decreased at a fixed ratio, thereby facilitating the control of the thickness of the microchannel flat tube and improving the heat exchange efficiency of the third channel. | 2021-05-27 |
