Abstract: The double-tube heat exchanger has an outer tube and an inner tube inserted into the outer tube, is provided with an inside channel within the inner tube and an outside channel between the inner tube and the outer tube, and is configured to exchange heat between the fluid flowing in the inside channel and the fluid flowing in the outside channel. The inner tube has an uneven portion having unevenness on the outer peripheral surface. A large-diameter sealing portion is interposed between one axial end of the outer tube and the inner tube. A small-diameter sealing portion, which has a smaller diameter than the large-diameter sealing portion, is interposed between the other axial end of the outer tube and the inner tube. The outside channel and the uneven portion are arranged using the difference in axial position and diameter between the large-diameter sealing portion and the small-diameter sealing portion.

Each heat exchange assembly includes a fin plate and at least one heat exchange tube. The heat exchange assembly includes a main heat exchange area. The heat exchange tube is connected with the fin plate. The heat exchange tube at least partially protrudes from at least one side of the fin plate. In addition, in the main heat exchange area corresponding to two adjacent heat exchange assemblies, at least two adjacent heat exchange tubes are staggered along an array direction of the heat exchange assemblies. The two heat exchange tubes respectively belong to the two adjacent heat exchange assemblies. The present disclosure is beneficial to improve the performance of the heat exchanger.

Abstract: A heat exchanger includes a first collecting pipe, a number of heat exchange tubes and a partition plate. The heat exchange tubes are inserted into the first collecting pipe. By means of the partition plate, a first inner cavity of the first collecting pipe is divided into a first sub-cavity and a second sub-cavity. One end of each heat exchange tube is in communication with the first sub-cavity. In the process of a refrigerant entering the first collecting pipe, the refrigerant flows into the second sub-cavity firstly, and forms a severe turbulence effect after interacting with the heat exchange tubes inserted into the second sub-cavity. Then, the refrigerant flows into the first sub-cavity through holes provided in the partition plate, and then flows into the heat exchange tubes. As a result, the uniformity of the two-phase refrigerant distribution can be relatively improved.

Abstract: Heat transfer between a fluid-bearing flexible tube and a heat-conducting surface is improved by fixing a flexible heat-conducting sheath to the flexible tube and by compressive fixing that distorts the tube and deforms the sheath and/or the surface. The tube can be made of cross-linked polythene (PEX). The sheath can be spirally wound high-purity aluminum wire. The sheath enables efficient heat transfer between the outer surface of the tube and the heat-conducting surface. Applications include radiant heating and cooling. Tube layout can be customized and variable tube spacing is possible, for example by using a castellated layer to support the tube.

Abstract: An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes. The spring portion includes two arms. One of the two arms has one thin portion defining one recess dented in one direction in a thickness direction. The other of the two arms has the other thin portion defining the other recess dented in the other direction in the thickness direction. The one thin portion and the other thin portion are resiliently movable in a width direction within a clearance formed by the recesses, while overlapping one another in the thickness direction.

Abstract: An evaporator assembly for an ice-making apparatus having a vertical, substantially flat freeze surface, a refrigerant circuit, and a freeze template. The freeze template is thermally coupled between the freeze surface and the refrigerant circuit, and is formed of a plurality of regions arranged in a plane and interconnected by strips having a smaller dimension in the plane than the regions. Interface locations between the freeze template and the freeze surface define where on the freeze surface ice is to be formed. During a freeze cycle, expanded refrigerant is passed through the refrigerant circuit, and water is run over the freeze surface. During a harvest cycle, compressed refrigerant is passed through the refrigerant circuit, wherein heat transfers from the refrigerant circuit to the freeze surface until the freeze surface is warmed to a temperature sufficient to allow ice formed on the freeze surface to fall from the freeze surface by a force of gravity.
