A condenser includes a fluid inlet in an upper manifold and a fluid outlet in a lower manifold. The condenser includes multiport tubes provided with a plurality of separate flow channels which are delimited by outer opposite side walls and internal intermediate walls extending between the outer opposite side walls of the tubes. The multiport tubes define a channel space between them. A plurality of cooling plates extend between the upper manifold and the lower manifold. The cooling plates are in thermal contact with the multiport tubes to receive a heat load from fluid in the flow channels. The cooling plates have outer edges which protrude out from the channel space and are directed away from the channel space.

A vacuum system, including a condenser including a first inlet, a first outlet, and a second outlet, a first ejector connected to a motive fluid source, and a second ejector connected to the motive fluid source and the condenser.

A chiller including a heat transfer tube and a method for controlling a chiller to determine a degree of contamination of a heat transfer tube are provided. As a degree of contamination of the heat transfer tube may be determined and a notification provided to a user regarding whether to clean the heat transfer tube, the chiller may be managed efficiently and an operation performance of the chiller may be maintained well.

A refrigerator includes a vacuum insulated cabinet structure having an exterior wrapper with a plurality of exterior walls exposed to ambient conditions. One of the exterior walls includes an outer surface and an inset portion that is inwardly disposed relative to the outer surface of the exterior wall. A skin condenser system is disposed within the inset portion along an outer surface of the inset portion. The skin condenser system includes a coil array defined by a coil disposed in a coil pattern. The skin condenser system further includes a cover assembly covering the coil array and in thermal communication with the coil array to facilitate the dissipation of heat to the ambient surroundings.

A temperature homogenizing container and a refrigerator having same. The container comprises a body and an accommodating space that is enclosed by the body. The body comprises several capillary tube cavities provided therein and allowing flow of a heat exchange medium. A micro-tooth structure is provided on the inner wall of each capillary tube cavity. The heat exchange medium may flow in the capillary tube cavities along an extension direction of the capillary tube cavities. By setting the container body to comprise several capillary tube cavities therein, the temperature homogenizing effect and heat exchange efficiency of the container are improved; by providing the micro-tooth structure, the heat exchange efficiency is further improved; the temperature difference of different areas in the container is reduced, and temperature homogenization in the container is achieved.

A condenser (100), comprising a shell (112), an inlet pipe (120), and an anti-impact plate (204). The shell (112) has an accommodating cavity (202). The inlet pipe (120) is a circular pipe having a gradually increasing inner diameter from the inlet to the outlet. The inlet pipe (120) is arranged to pass through the upper end of the shell (112), the outlet of the inlet pipe (120) being accommodated in the accommodating cavity (202). The anti-impact plate (204) is accommodated in the accommodating cavity (202), and the anti-impact plate (204) is positioned below the outlet of the inlet pipe (120). There is a gap between the anti-impact plate (204) and the outlet through which fluid flowing from the outlet can flow. The condenser (100) can reduce the friction loss and local resistance of the refrigerant gas flowing into the inlet pipe (120), such that the dynamic pressure of the refrigerant gas entering the condenser (100) is partially converted into static pressure, and reduce the static pressure loss of the refrigerant gas entering the cylinder from the inlet, thereby increasing the condensing pressure of the refrigerant gas in the condenser (100) to enhance the heat exchange performance.

A heat exchanger is provided, including a heat exchanger core. The heat exchanger core at least includes a first core part, a second core part and a third core part which are stacked. The first core part, the second core part and the third core part are formed by stacking plates. The third core part is located between the first core part and the second core part. The first core part is in the form of unilateral flow. The second core part is in the form of diagonal flow. The third core part can realize transformation of flow channel forms of the first core part and the second core part, and is stacked with the first core part and the second core part, and thus the heat exchange efficiency is good.

A liquid-cooled condenser of a vehicle cooling system includes a refrigerant inlet and outlet mouths, through which the refrigerant fluid flows, and a liquid inlet mouth and a liquid outlet mouth through which the liquid flows. The liquid-cooled condenser includes upper and lower plate-like end elements, wherein the mouths are on the plate-like end elements. Intermediate plate-like elements in their mutual stacking define a refrigerant region, in which the refrigerant fluid flows, having refrigerant supply sections, in fluidic communication with the refrigerant inlet and outlet mouths. Transverse refrigerant sections, and a liquid region, into which the liquid flows, include liquid supply sections, in fluidic communication with the liquid inlet and outlet mouths. Transverse liquid sections alternate with the transverse refrigerant sections. A tubular element extending into the outlet refrigerant supply section, includes transverse section smaller than a transverse section of the outlet refrigerant supply section, forming a condensation gap.
