摘要： A heat exchanger mounted in an air condition is constructed such that at least one row of heat conduction pipe groups are arranged so as to obstruct an air passage. Each heat conduction pipe groups is constructed such that a plurality of heat conduction pipes 22 are arranged in parallel with each other and a fine wire 23 made of a metallic material having excellent heat conductivity is spirally wound around each adjacent heat conduction pipes 22. Thus, performances of the heat exchanger can be improved without a possibility that the air conditioner is designed with larger dimensions. In addition, the heat exchanger includes a plurality of heat conduction pipes 39 arranged in the form of at least one row with a constant distance between adjacent ones and a plurality of twisted wires 40. The twisted wires 40 are arranged so as to alternately come in contact with one side and opposite side of each heat conduction pipe 39 extending at a right angle relative to the row direction of each heat conduction pipe 39, and moreover, alternately come in contact with one side and opposite other side of each heat conduction pipe 39 extending in the longitudinal direction. With this construction, high heat conductivity can be realized, and an occurrence of clogging with dew droplets can be prevented while maintaining a heat conduction area.

摘要： A heat exchanger comprises a plurality of regularly corrugated fins placed one over another in layers at regular pitches in a back-to-back arrangement so as to form alternate wide and narrow fluid passage between the adjacent corrugated fins, and each having a plurality of small through holes, a plurality of collars formed in a staggered arrangement, and an annular area not having any small through hole and formed so as to surround the root of each collar; and pipes for passing a secondary fluid therethrough, each inserted through the collars of the layers of the corrugated fins. The height of the collar from the lower surface of the annular area corresponds to the pitch between the adjacent corrugated fins, and thereby the corrugated fins can be assembled at regular pitches simply by placing one over another. The pipes are expanded after being inserted through the collars so that the pipes are firmly and closely joined to the collars for satisfactory heat transmission between the fins and the pipes.

摘要： A heat exchanger comprises a plurality of perforated and regularly corrugated heat transfer plates arranged in a ridge-to-ridge and furrow-to-furrow arrangement, so as to form primary fluid passages each consisting of alternate expanded sections and narrowed sections arranged along the direction of flow of a primary fluid, and a plurality of pipes for passing a secondary fluid therethrough, the pipes penetrating through and across the heat transfer plates. Oblique guide grooves are formed in the surfaces of each heat transfer plates to facilitate the downward flow of the condensate condensed over the surfaces of the heat transfer plates, the grooves being inclined closer to the vertical than to the horizontal to facilitate downward flow of any vapor condensed on the plates from the primary fluid whereby the heat transfer plates dry quickly for efficient heat exchange between the primary and secondary fluids.
