    • A fan guard (4) for an air heat exchanger (2) and an air heat exchanger comprising such a fan guard is provided. The fan guard comprises a grid (8) arranged to enclose a fan (6) of the air heat exchanger and a first attachment means (18) arranged to engage with a second attachment means (38) of the air heat exchanger to attach the fan guard to the air heat exchanger. The second attachment means projects from a surface (44) of the air heat exchanger. The fan guard is characterized in that the first attachment means comprises a hook (22) having a first end (24) at which the hook is connected to the grid. The hook is arranged to just partially encircle the second attachment means to attach the fan guard to the air heat exchanger. The hook has an opening (36) enabling the hook to move into partial encirclement of the second attachment means when the fan guard is rotated in relation to the air heat exchanger, around a center axis (C) of the fan guard, in a first rotation direction (D1), and out of partial encirclement of the second attachment means when the fan guard is rotated in relation to the air heat exchanger, around the center axis of the fan guard, in a second rotation (D2) direction which is opposite to the first rotation direction.
    • 提供了一种用于空气热交换器(2)的风扇护罩(4)和包括这种风扇护罩的空气热交换器。 风扇护罩包括布置成封闭空气热交换器的风扇(6)的格栅(8)和布置成与空气热交换器的第二附接装置(38)接合的第一附接装置(18),以将风扇 保护空气热交换器。 第二附接装置从空气热交换器的表面(44)伸出。 风扇护罩的特征在于,第一附接装置包括具有第一端(24)的钩(22),钩在该第一端连接到栅格。 挂钩布置成仅部分地环绕第二连接装置,以将风扇护罩附接到空气热交换器。 当风扇护罩相对于空气热交换器围绕风扇护罩的中心轴线(C)旋转时,钩具有开口(36),使得钩能够移动到第二附接装置的部分包围中 旋转方向(D1),并且当风扇护罩相对于空气热交换器围绕风扇防护件的中心轴线旋转时,第二连接装置的部分包围不在第二旋转(D2)方向上 到第一旋转方向。

    • A fin structure 16 for heat-exchanging, the fin structure 16 being mounted on a heat-dissipating portion 15 of a Stirling cycle cooler 7, wherein the fin structure 16 is configured by coupling a plurality of unit structures 16a, 16b, the plurality of unit structures 16a, 16b being split by a plurality of surfaces extending from a inner circumference of the fin structure 16 toward an outer circumference thereof. The fin structure 16 is configured thus way, whereby it can be mounted on the heat-dissipating portion 15 so as to sandwich the heat-dissipating portion 15 from the outer circumference thereof by the plurality of unit structures 16a, 16b coupled with each other. Accordingly, when mounting the fin structure 16, large force is not required, no adhesive filler is applied to an unneeded portion of the Stirling cycle cooler 7, and generating a scratch or a distortion on the casing of the Stirling cycle cooler 7 can be prevented.
    • 用于热交换的翅片结构16,翅片结构16安装在斯特林循环冷却器7的散热部分15上,其中翅片结构16通过将多个单元结构16a,16b,多个 单元结构16a,16b由从翅片结构16的内周向其外周延伸的多个表面分开。 翅片结构16由此构成,由此可以将其安装在散热部15上,以便通过彼此耦合的多个单元结构16a,16b将散热部15从外周夹住。 因此,当安装翅片结构16时,不需要大的力,因此不会在斯特林循环冷却器7的不需要部分施加粘合剂填料,并且可以防止在斯特林循环冷却器7的壳体上产生划痕或变形。 。
