    Abstract: A thermoelectric module that has a thermoelectric element, an axial flow fan, and a heat sink and that is installed at a rear wall of the storage chamber to cool the storage chamber. The heat sink has a base configured to come in surface contact with the thermoelectric element, fins protruding from the base toward the axial flow fan and spaced apart from each other, and heat pipes having base passing portions passing through the base and fin passing portions passing through the fins and configured to transfer heat from the base to the fins. Each of the fins includes a first part arranged opposite to the hub and a second part disposed at one of both sides of the first part to face the vanes and protruding further from the base toward the axial flow fan than the first part.

    Abstract: A refrigerating cycle apparatus and a method of operating the same are provided. For a refrigerating cycle having a plurality of compressors connected in series for multi-stage compression, an inner space of each compressor and a pipe of the refrigerating cycle may be connected via an oil collection pipe, and oil may be discharged into the refrigerating cycle by pressure reversal during a pressure balancing operation, so as to allow the discharged oil to be collected into a high-stage compressor or a low-stage compressor. Accordingly, an amount of oil may be uniformly maintained in each of the plurality of compressors to prevent losses due to friction and/or increases in power consumption due to a lack of oil in one or more of the compressors. The structure of a device and pipes for performing oil balancing between the compressors may be simplified to enhance efficiency of the compressors.

    Abstract translation: 提供了一种制冷循环装置及其操作方法。 对于具有串联连接多级压缩的多台压缩机的制冷循环，每个压缩机的内部空间和制冷循环的管道可以经由采油管连接，并且可以通过以下方式将油排出到制冷循环中： 在压力平衡操作期间的压力反转，以便将排放的油收集到高级压缩机或低级压缩机中。 因此，可以在多个压缩机的每一个中均匀地保持一定量的油，以防止由于一个或多个压缩机中的油不足而导致的摩擦损失和/或功率消耗增加。 可以简化用于在压缩机之间执行油平衡的装置和管道的结构，以提高压缩机的效率。

    Abstract: A cold air supply device is applied to an entrance refrigerator. The cold air supply device includes a thermoelectric element forming a heat absorbing surface and a heat generating surface, a cold sink in contact with the heat absorbing surface, a heat absorption fan disposed above the cold sink, a heat sink in contact with the heat generating surface, a heat dissipation fan disposed below the heat sink, and an insulation material disposed between the cold sink and the heat sink to block heat transfer. The cold sink includes a sink body, and a plurality of heat exchange fins arranged on the upper surface of the sink body. Absorption pads are provided on both side edges of the sink body to absorb condensed water generated on the surface of the cold sink.
