A method for manufacturing an evaporator for ice-making includes: a preparation step for preparing a plate member, a finger member, and a capillary tube, the plate member being provided with a through hole and formed as a developed view of a tube; an insertion step for inserting the finger member into the through hole so that the finger member at least partially passes through the through hole; a connection step for fixedly connecting the finger member to the plate member; an insert placement step for placing at least a part of the capillary tube on the plate member; and an evaporation tube formation step for forming an evaporation tube, which is provided with a refrigerant flow path through which a refrigerant flows, by bending the plate member into a tube shape and connecting end portions.

In one general aspect, a converging split-flow microchannel evaporator is disclosed. It includes a conductive contact surface to mate to a surface to be cooled, with a core mounted in thermal connection with the conductive surface that defines at least one layer of microchannels. Within the core, one inlet restriction restricts the flow into each microchannel in a first group of the microchannels, and another restricts the flow into each microchannel in a second group. A centrally located fluid outlet receives the flows from opposite ends of the microchannels in the two groups. A check valve can be provided to help ensure ready startup without reverse flow.

An ice maker evaporator assembly having an evaporator pan with a back wall and left, right, top and bottom sidewalls extending from the back wall, and a freeze plate located within the evaporator pan. Refrigerant tubing is thermally coupled to the back wall of the evaporator pan opposite the left, right, top and bottom sidewalls. A first layer of insulation is formed on the refrigerant tubing. An evaporator housing having a housing back wall and housing left, right, top and bottom sidewalls extending from the housing back wall is attached to the evaporator pan and covers refrigerant tubing. A second layer of insulation is formed on top of the first layer of insulation.

The purpose of the present invention is to provide an air guide-integrated evaporation cooler which allows a plurality of barrier plates, heat exchangers, and air guides for forming a dry channel and a wet channel to be integrally manufactured by a simple process, and a method of manufacturing the same. The air guide-integrated evaporation cooler for implementing the purpose includes a plurality of barrier plates; and gap units including a plurality of bars positioned between the plurality of barrier plates, disposed to be spaced apart from each other at a center portion thereof, and configured to form heat exchangers, and guides disposed at edges of the plurality of barrier plates and configured to determine a direction of a fluid flow.

An evaporator includes a cool storage material container. The cool storage material container contains a cool storage material and is disposed in a second part of the spaces. The cool storage material container includes a container main body portion joined to the refrigerant flow tubes. The outward projecting portion extends from an upper end of the leeward edge or windward edge of the container main body portion. The outward projecting portion has an expansion portion projecting from the container main body portion and projecting thickness of the expansion portion is greater than a thickness of the container main body portion. The expansion portion is located outward of the fins. At least one of left and right side walls of the expansion portion is so constructed to deform when an internal pressure in the cool storage material container increases beyond a predetermined pressure.

A refrigeration cycle apparatus including a refrigerant circuit including a compressor, an indoor heat exchanger, an expansion device, an outdoor heat exchanger, an outside air temperature sensor, and a controller configured to perform a hot gas defrosting operation and a reverse-defrosting operation based on a temperature obtained by the outside air temperature sensor. In the hot gas defrosting operation, hot gas discharged from the compressor without passing through the indoor heat exchanger is supplied to the outdoor heat exchanger. In the reverse-defrosting operation, refrigerant passing through the indoor heat exchanger is supplied from the compressor to the outdoor heat exchanger. The controller has at least a mixed defrosting operation mode in which the hot gas defrosting operation and the reverse-defrosting operation are performed in sequence. The controller is configured to start the mixed defrosting operation mode when the temperature obtained by the outside air temperature sensor satisfies a preset condition.

A refrigerator may include a cabinet defining a low-temperature storage space and a machine chamber in which a compressor and a condenser are disposed; and an evaporator disposed in rear of the storage space, wherein air flows upwards along the evaporator and thus cools down to lower a temperature of the storage space. The evaporator may include a cooling pipe in and along which refrigerant flows; and a plurality of cooling fins surrounding an outer face of the cooling pipe. The cooling pipe may be constructed so that the refrigerant flows downward along and in the cooling pipe.
