A heat exchanger system is disclosed by embodiments of the present invention. The heat exchanger system comprises an upper manifold, a middle manifold and a lower manifold arranged successively from top to bottom, wherein a first heat-exchanging tube is arranged between the upper manifold and the middle manifold, and a second heat-exchanging tube is arranged between the middle manifold and the lower manifold. The middle manifold has a first chamber and a second chamber separated from each other. During circulation of refrigerant, the refrigerant in the upper manifold flows through the first heat-exchanging tube down to the first chamber, and flows via a first communicating part into the chamber of the lower manifold, and subsequently the refrigerant flows through the second heat-exchanging tube up into the second chamber and then returns via a second communicating part to the upper manifold.

Disclosed herein is an apparatus for cooling a battery including: a cooling channel disposed to exchange heat with a battery module by cooling water and provided with an inlet into and an outlet through which the cooling water is introduced and discharged; branch channels formed in the cooling channel to be branched in parallel with a longitudinal direction of the cooling channel to make the cooling water introduced through the inlet flow toward the outlet while the cooling water passes through the branch channels; and a plurality of flow guides disposed between the inlet and the branch channels at a predetermined interval along a direction in which the branch channels are branched and guiding the flow of cooling water introduced through the inlet to allow the cooling water to be uniformly introduced into the respective branch channels.

A heat exchanger for cooling product gas generated from biomass includes a cylindrical main body, a rod-shaped component, a gas inlet and a gas outlet. The cylindrical main body has a circumferential cladding. An annular flow channel is formed in the cylindrical main body around the rod-shaped component, which extends axially in the main body. The gas inlet and gas outlet are disposed towards opposite ends of the main body. The gas inlet is tubular and enters the annular flow channel tangentially to the circumferential cladding and perpendicularly to the axial direction of the cylindrical main body. The velocity of the cooling product gas is maintained by making the cross-sectional area of the gas outlet smaller than that of the gas inlet. A helical shaped guide plate is disposed in the annular flow channel and has an outer circumferential edge that seals against an inner surface of the circumferential cladding.

A heat exchanger including a shell forming a generally cylindrical housing, a plurality of dividers within the shell extending along the length of the shell, wherein the dividers separate the shell into sections and each section forms a shell pass. The heat exchanger can further include a plurality of tube passes, wherein at least one tube pass is contained within each of the shell passes, and each tube pass comprises a plurality of tubes extending along the length of the shell, a shell inlet passage configured to receive a first fluid into a first shell pass and a shell outlet passage configured to discharge the first fluid from a last shell pass, and a plurality of shell pass passages formed in the dividers near a first end or a second end of the shell configured to allow flow of the first fluid from one shell pass to the next shell pass. In addition, the heat exchanger can include a tube inlet passage configured to receive a second fluid into a first tube pass and a tube outlet passage configured to discharge the second fluid from a last tube pass and a pair of shell heads configured to couple to the first end and the second end of the shell, wherein the shell heads are divided into a plurality of sections and each section is configured to route flow of the second fluid from one tube pass to the next tube pass.

The present application provides a falling film evaporator. The falling film evaporator comprises a housing, a gas outlet, a cover, a gas flow channel, and a plurality of flow guide members. The housing has a length direction and a height direction, and the housing defines an accommodating cavity. The gas outlet is provided at the upper portion of the accommodating cavity. The cover is provided in the accommodating cavity and defines a cover accommodating cavity, the cover accommodating cavity has a lower cover opening located below, and the cover accommodating cavity is configured to accommodate at least one part of a heat exchange tube bundle. The gas flow channel is located between the housing and the cover and enables the lower cover opening of the cover accommodating cavity to be in communication with the gas outlet. The plurality of flow guide members are arranged in the gas flow channel along the height direction of the housing. Here, in the height direction of the housing, one of two adjacent flow guide members is connected to the housing and is separated from the cover by a certain distance, and the other of the two adjacent flow guide members is connected to the cover and is separated from the housing by a certain distance. The falling film evaporator in the present application has the advantage of being high in gas-liquid separation efficiency, and the machining process of the flow guide members of the falling film evaporator is simple.
