    • An outdoor heat exchanger section has lower and upper cabinet sections between which a generally horizontal louvered lower section top cover is disposed. The sides of the lower cabinet section are louvered to promote the entry and upward movement of air thereinto and through a heat exchange coil disposed about the inner periphery thereof. Air drawn into the lower cabinet section is discharged though the radially louvered portion of the lower section top cover. The radial top cover louvers are angled so as to partially deflect the upwardly flowing air leaving the lower cabinet section to the horizontal. The top of the upper cabinet section is essentially flat and solid and overlies the lower cabinet section top cover louvers so that neither debris nor the elements can enter the lower cabinet section from above. The sides of the upper cabinet section are angled and include louvers which are themselves angled, both of which features cooperate to efficiently direct air out of the upper cabinet section in a direction which is upward and away from the lower cabinet section. The upper cabinet section includes a stator which provides support for the upper cabinet section top and which assists in the efficient direction of air to and out of the upper cabinet section sides.
    • 室外热交换器部分具有下部和上部机柜部分,在其之间布置有大致水平的百叶窗下部顶盖。 下柜部分的侧面被打开以促进空气的进入和向上运动并通过围绕其内周设置的热交换线圈。 被抽入下部机柜部分的空气通过下部顶盖的径向百叶窗部分排出。 径向顶盖百叶窗是成角度的,以便将向下流动的空气部分地偏转到下部机柜部分到水平面。 上部机柜部分的顶部基本上平坦且牢固,并且覆盖在下部机柜部分顶盖百叶窗上,以使碎片和元件都不会从上方进入下部机柜部分。 上部机柜部分的侧面是成角度的,并且包括本身成角度的百叶窗,两个这些特征相配合以有效地将空气从上部机柜部分引导向上并远离下部机柜部分的方向。 上部机柜部分包括定子,该定子提供对上部机柜部分顶部的支撑,并且有助于空气进出上部机柜部分侧面的有效方向。

    • The method of joining the contiguous surfaces of telescoped end portions of tube members wherein at least one of the surfaces to be joined is coated with a layer of solder. A heated forming means is applied to the telescoped end portion to reflow the solder while simultaneously applying sufficient pressure in a radial direction to progressively reduce the radial clearance between the end portions in an axial direction toward the open end of the female member. The temperature and pressure applied is sufficient to provide melted solder between the surfaces to be joined as the crimping action proceeds axially so that excess solder is forced hydraulically out of the open end of the female member as the radial clearance is progressively reduced to a minimum. The scrubbing action of the molten solder as it is forced progressively from the radial clearance is effective in removing the oxide from the surfaces to be joined thereby completing a joint between the members.
    • 连接管构件的可伸缩端部的连续表面的方法,其中待接合的表面中的至少一个被一层焊料涂覆。 将加热的成形装置施加到伸缩端部以回流焊料,同时在径向方向上施加足够的压力,以逐渐减小端部之间在轴向方向上朝向阴构件的开口端的径向间隙。 施加的温度和压力足以在压接作用轴向地进行时在要接合的表面之间提供熔融的焊料,使得当径向间隙逐渐减小到最小时,多余的焊料被液压地迫使其从阴构件的开口端流出。 熔融焊料在从径向间隙逐渐强制时的擦洗作用对于从待接合表面去除氧化物是有效的,从而完成部件之间的接合。
