    • This invention relates to a plate heat exchanger designed for heat exchange between gaseous media, preferably air. The heat exchanger comprises a plurality of thin plates (1a-c) stacked upon each other and provided with distance members (2) lengthwise in the flow direction in the form of pleats. Every second plate is offset 90° in relation to the adjacent plate in order to form throughgoing ducts (3) of largely rectangular cross-sections. In order to reduce the material thickness and to increase the heat transfer capacity and at the same time to maintain the flow resistance at a low level, according to the invention the plates between the lengthwise distance members (2) are furnished with a friction pressure drop forming fine structure (4) in the form of corrugations essentially at right angles to the distance members. Moreover, the invention provide means to obtain an efficiant seal between the separate gas flow passages in the heat exchanger. Thus each contact plate at its two end sides terminating along the distance members displays a lengthwise edge zone area, that each contact plate at its two end sides terminating across the distance members displays a lengthwise part within which a folding edge is arragned. The edges are in order to be joined with an adjacent plate folded around the edge zone area of the adjacent plate and thus form a folded edge, which extends over the corresponding edge zone area and encloses it. The folded edge and the enclosing material display a lengthwise pleating which extends along the whole width of the plate in order to lock the folding edge. Whithin the pleating fine structure is partly deformed by being pressed against each other and thus forms an effective seal between the plates. The heat exchanger plates are preferably made of aluminium.
    • 本发明涉及一种设计用于在气态介质,优选空气之间进行热交换的板式热交换器。 热交换器包括多个彼此堆叠的薄板(1a-c),并且在褶皱形式的长度方向上在流动方向上设有距离构件(2)。 每个第二板相对于相邻板偏移90°,以形成具有大致矩形横截面的通道(3)。 为了减小材料厚度并增加传热能力并同时将流动阻力保持在低水平,根据本发明,纵向间隔构件(2)之间的板配备有摩擦压降 形成基本上与间隔构件成直角的波纹形式的精细结构(4)。 此外,本发明提供了用于在热交换器中的分开的气体流动通道之间获得有效密封的手段。 因此,每个接触板在其沿着间隔构件终止的两个端部处显示纵向边缘区域区域,每个接触板在其两端侧横跨间隔构件终止的纵向部分显示出折叠边缘被设置在其中。 这些边缘是为了与相邻板的边缘区域周围折叠的相邻板连接,并因此形成折叠边缘,该折叠边缘在对应的边缘区域区域上延伸并包围它。 折叠边缘和封装材料显示纵向褶皱,其沿着板的整个宽度延伸以锁定折叠边缘。 而在打褶的精细结构中,由于彼此压紧而部分变形,因此在板之间形成有效的密封。 换热器板优选由铝制成。

    • An automotive oil cooler (10) used in combination with an oil filter (14). The oil cooler (10) is comprised of a heat exchange element (10) which is constructed of a plurality of heat transmission plates (18). The heat transmission plates (18) are piled up one upon another and fixedly secured by brazing in such a manner as to define oil and water flowing spaces on the opposite sides of each heat transmission plate (18). Oil and water flow through the oil and water flowing spaces, respectively. The heat exchange (10) element is formed with a plurality of oil supply passages (P₁, P₂) through which oil is supplied to the oil filter (14), an oil inflow passage (P₁) communicating with the oil flowing space to receive oil from the oil filter (14), an oil outflow passage (P₂) communicating with the oil flowing space to receive oil from the oil flowing space, a water inflow passage (P₃) communicating with the water flowing passage, and a water outflow passage (P₄) communicating with the water flowing space to receive water from the water flowing space. Additionally, an under cover (54) is fixedly secured to the heat exchange element (10) and formed therein with a plurality of vertically extending partition walls (62 A-E). The partition walls (62 A-E) define an oil supply chamber (66) through which oil is supplied to the oil supply passage (P₁) of the heat exchange element (10), an oil discharge chamber through which oil from the oil outflow passage of the heat exchange element (10) is discharged outside of the under cover (54), a water introduction chamber (64) through which water is introduced into the water inflow passage (P₃) of the heat exchange element (10), and a water discharge chamber (72) through which water from the water outflow passage (P₄) of the heat exchange element (10) is discharged outside of the under cover (54).
