    • A cooling device includes a heat-radiating device and a centrifugal pump provided in a closed circulation passage for circulating refrigerant. The centrifugal pump contacts and absorbs heat from heat-generating electronic parts by heat exchange of the refrigerant therein to radiate the heat via the heat-radiating device. The centrifugal pump includes a lower casing that comes into contact with the heatgenerating electronic parts, an upper casing disposed to face the lower casing to form a pump chamber, and an impeller sandwiched between the upper casing and the lower casing. The lower casing includes a recessed conical surface facing the impeller, at least one protrusion provided in a center portion of the recessed conical surface and a contact face with which the heat-generating electronic parts come into contact formed directly below the protrusion on an opposite side of the recessed conical surface.
    • 冷却装置包括设置在用于循环制冷剂的封闭循环通道中的散热装置和离心泵。 离心泵通过其中的制冷剂的热交换而接触和吸收来自发电电子部件的热量,以通过散热装置辐射热量。 离心泵包括与发热电子部件接触的下壳体,与壳体相对配置以形成泵室的上壳体和夹在上壳体和下壳体之间的叶轮。 下壳体包括面向叶轮的凹入的圆锥形表面,设置在凹形圆锥形表面的中心部分中的至少一个突起和发热电子部件接触的接触面,形成在相对侧的突起下方 的凹入的圆锥形表面。

    • A cooling device including a heat-radiating device and a centrifugal pump provided in a closed circulation passage for circulating refrigerant. The centrifugal pump comes into contact with heat-generating electronic parts to absorb heat from the heat-generating electronic parts by the heat exchange of the refrigerant therein to radiate the heat via the heat-radiating device. A pump chamber of the centrifugal pump is defined by a combination of a plurality of casings, that is, an upper casing, a ring-shaped sealing member and a lower casing. A contacting surface that comes in a surface contact with the heat-generating electronic parts, and a recessed conical surface that faces an impeller are formed in the lower casing of the casings that comes into a direct contact with the heat-generating electronic parts. A plurality of heat-radiating pins protruding toward the impeller is provided in a center portion of the recessed conical surface.
    • 一种冷却装置,包括设置在用于循环制冷剂的封闭循环通道中的散热装置和离心泵。 离心泵与发热电子部件接触,以通过其中的制冷剂的热交换来吸收来自发热电子部件的热量,以通过散热装置辐射热量。 离心泵的泵室由多个壳体,即上壳体,环形密封构件和下壳体的组合限定。 在与发热电子部件直接接触的壳体的下壳体中形成有与发热电子部件表面接触的接触面和面向叶轮的凹入的圆锥面。 在凹入的圆锥形表面的中心部分设置有朝向叶轮突出的多个散热销。
