A heat exchanger assembly includes: a frame; a heat exchanger panel mounted to the frame and configured to exchange heat with air flowing therethrough, the heat exchanger panel being disposed at an inclined orientation; a fan assembly disposed vertically above the heat exchanger panel; and a sound dampening device disposed within an interior space of the heat exchanger assembly such that air is pulled into the interior space through the heat exchanger panel and then flows through the sound dampening device before being discharged from the heat exchanger assembly via the fan assembly. The sound dampening device includes baffle members having sound absorbing material and spaced apart from one another for allowing air flow therebetween. Each baffle member extends at an angle relative to a plane extending through the upper and lower ends of the heat exchanger panel so as to direct air flow upwardly toward the fan assembly.

A casing has a plurality of inner walls for guiding air from the heat exchanger panel toward the fan assembly. The inner walls include a sloped wall. A distance between an upper end of the sloped wall and a fan rotation axis is greater than a distance between a lower end of the sloped wall and the fan rotation axis. The sloped wall is adjacent to the upper end of the heat exchanger panel such that the part of the fan impeller rotates vertically above the sloped wall.

A shell and tube heat exchanger has elongated shell having first and second opposing ends and an open interior. A core divides the open interior of the shell into first and second enclosed portions. The shell has first and second tube fluid openings at opposing ends. End plates divide the first and second enclosed portions into manifold portions and enclosed shell chamber portions. Tubes extend from the end plates, through the enclosed shell chambers to the core. Shell fluid openings are at sides of the elongated shell, a first fluid opening communicating with the first shell chamber, and a second fluid opening communicating with the second shell chamber. The shell has a long axis, and the end plates are angled relative to the long axis. The tubes are polygonal with rounded corners and straight sides. The heat exchanger can be used for both evaporation and condensation processes.

A heat exchanger including a shell having a longitudinal axis, a plurality of baffles, such as elliptical sector-shaped baffles, each mounted in the shell at a helix angle H.sub.B to guide a fluid flow into a helical pattern through the shell. Each of the plurality of baffles includes an outer circumferential edge, a proximal radial edge, a distal radial edge, a proximal side, a distal side, and a plurality of spaced apart holes that are traversed by a plurality of axially extending tubes. Each of the first plurality of seal strips is disposed from a proximal of the plurality of baffles to a distal of the plurality of baffles.

A heat exchanger includes a core defining a first passageway for a first fluid flow and a second passageway for a second fluid flow. The core includes an assembly of a plurality of unit cells coupled together. Each unit cell defines a first passageway portion within an interior volume and a second passageway portion at an exterior surface. Each unit cell includes a plurality of first openings into the interior volume and forms the second passageway in volumes between the plurality of unit cells. The assembly is shaped to combine and divide the first fluid in the first passageway portion and combine and divide the second fluid in the second passageway portion during exchange of heat between the first fluid and the second fluid. Each second passageway portion receives the second fluid from three other second passageway portions. The heat exchanger further includes at least one baffle in at least one of the first passageway or the second passageway to route the first fluid flow independently from the second fluid flow.

A cooling device includes a cooler disposed inside a shell main body formed in a cylindrical shape, and having a first surface facing an inlet nozzle and an outlet nozzle, and a partition member fixed to the first surface, and partitioning a portion between the cooler and an inner peripheral surface of the shell main body into a first space communicating with the inlet nozzle and a second space communicating with the outlet nozzle. The partition member includes a main partition plate disposed between the inlet nozzle and the outlet nozzle in an axial direction, a first guide portion extending from an end portion of the main partition plate toward a first end surface of the shell main body, and a second guide portion extending from an end portion of the main partition plate toward a second end surface of the shell main body.

The present disclosure relates to heat exchangers and heat exchange systems such heat exchangers. The heat exchangers include a shell having an inlet and an outlet and heat exchange tube bundles arranged therein. The shell includes a first region communicating with the inlet configured to accommodate the heat exchange tube bundles and a refrigerant input from the inlet. The refrigerant performs heat exchange with a fluid in the heat exchange tube bundles. A second region is arranged between the first region and the outlet and communicates with the first region and the outlet. A heating device is disposed in the second region. Embodiments may optimize spatial layout of the heat exchanger tube bundles, effectively improving the utilization of shell space of the heat exchanger the heat transfer efficiency of the heat exchanger at the same material cost, and enhance the overall performance, safety and reliability of the system.
