摘要:
A heat exchanger module unit that provides heat exchange between a fluid and a heat medium by indirect heat exchange through a phase-change material disposed between movement paths of the fluid and the heat medium movement paths, includes: a multiple number of plates having a partition, which is formed with a through-hole through which the fluid and the heat medium move, are stacked with a spacing gap, through which the fluid and the heat medium move, at one side of the partition; the spacing gaps are selectively connected through a connector connecting the respective through-holes so as to form a fluid passage and a heat medium passage through which the fluid and the heat medium move independently respectively; the spacing gap, in which the phase-change material is received, is located and disposed between the spacing gaps forming the fluid passage and the heat medium passage through which the fluid and the heat medium move respectively such that heat exchange is made between the fluid and the heat medium through the phase-change material. One of the fluid and the heat medium is disposed at one side of the phase-change material and another phase-change material is disposed at the opposite side thereof.

Disclosed are an air condenser (1) and a clothes dryer. The air condenser includes condensing air ducts (j) and a cooling pipeline (i) arranged crosswise. The condensing air ducts (j) include a first group of condensing air ducts and a second group of condensing air ducts, wherein air inlet ducts of the first group of condensing air ducts and air outlet ducts of the second group of condensing air ducts are at least partially arranged in a heat exchangeable manner; and air outlet ducts of the first group of condensing air ducts and air inlet ducts of the second group of condensing air ducts are at least partially arranged in a heat exchangeable manner. By arranging the first and the second groups of condensing air ducts which can partially perform heat exchange on the air condenser (1), heat exchange is performed between high-temperature and high-humidity air flowing out of a drum (3) of the clothes dryer and air condensed by the air condenser (1) to enter a heater (2), so that waste heat of high-temperature air in the condensing air ducts (j) can be effectively recycled, and loss of heat is reduced, thereby achieving a purpose of saving energy while increasing heat exchange efficiency.

摘要:
Refrigeration-based compressed-gas dryer comprising a group of heat exchangers (10), this group of heat-exchangers including a gas-to-gas heat exchanger (16), an evaporator (22), a condensate separator (30) and at least a refrigerating circuit (28), wherein in said gas-to-gas heat exchanger, which works as a heat recovery apparatus, there is provided a pre-cooling section (18) and a heating section (20), and wherein in said evaporator (22) there is provided a cooling section (24) for the compressed gas to be dried and an evaporation section (26) for a refrigerant medium, for said compressed gas to be cooled down to a desired dew point. Each individual heat exchanger in said group of heat exchangers (10) is formed of a plurality of heat-exchange stacks or circuits (80), which create a passageway (84) for the compressed gas and at least two passageways (85, 86) for the refrigerant medium, respectively, said heat-exchange stacks or circuits (80) being defined by a plurality of fins (81) attached to thin, planar sheet-metal plates (89) lying orthogonally to the fins. The increased number of passageways for the refrigerant medium enables the heat-exchange efficiency of the evaporator (22) to be improved.
摘要:
A heat exchanger (10, 110, 210) comprises at least a pre-cooling unit, or pre-exchanger (12), having a longitudinal development along at least a first longitudinal axis (L1), and at least a cooling unit, or evaporator (14, 114), having a longitudinal development along at least a second longitudinal axis (L2) and connected to the pre-exchanger (12) in order to define a fluid-dynamic circuit for the circulation of a fluid, such as air (A), in said pre-exchanger (12) and said evaporator (14, 114). The first longitudinal axis (L1) and said second longitudinal axis (L2) are angled with respect to each other by an angle comprised between 45° and 135°.
摘要:
Die Erfindung betrifft einen Druckgaskühler, insbesondere für Kompressoren, mit einem Rohrbündel (1) aus parallelen Kühlrohren (2) für die Durchleitung einer Kühlflüssigkeit und mit einem zylindrischen Gehäuse (3), das an seinem einen Ende geschlossen ist und an seinem anderen Ende eine stirnseitige Öffnung (4) zum Einsetzen des Rohrbündels (1) aufweist. Die Kühlrohre (2) sind einseitig an einen Rohrboden (5) eines in der stirnseitigen Öffnung (4) des Gehäuses befestigbaren Kopfstückes (6) angeschlossen. Am Umfang des Gehäuses (3) sind Stutzen (10, 11) für einen Gaseinlass und einen Gasauslass angeordnet, die in Gehäuselängsrichtung voneinander beabstandet sind. Erfindungsgemäß sind die Kühlrohre (2) des Rohrbündels (1) unter einem Anstellwinkel (α) von 2° bis 10° schräg zur Längsachse (12) des zylindrischen Gehäuses (3) ausgerichtet. Ferner ist zumindest der Gaseinlass-Stutzen (10) an einem Gehäuseabschnitt angeordnet, der infolge der Schrägstellung der Kühlrohre (2) von dem Rohrbündel (1) weiter beabstandet ist als der in Umfangsrichtung gegenüberliegende Gehäuseabschnitt.
