example 2

[0254] In the above-mentioned embodiment, the first cooling unit body portion 82 (fin holding portion 821) has an area larger than the area of ​​the first opening 52a when viewed from the front or the rear (when viewed from the front-rear direction), and accordingly, the In order to close the first opening 52a, the internal space SP and the space outside the distribution box 50 are partitioned. In this regard, it is preferable to configure and arrange the first cooling unit body portion 82 as described above from the viewpoint of reliably shielding the heat pipe 83 from the outdoor airflow AF and suppressing deterioration of the weather resistance of the heat pipe 83 .

[0255] However, as long as the heat pipe 83 does not extend from the space (internal space SP) in the distribution box 50 to the air supply space S1 outside the electronic component box, and the effect described in (9-1) above does not contradict, the first cooling The configuration aspect of the unit body por...

[0257] The configuration aspect of the first cooling unit 80 is not limited to the aspect shown in the above-mentioned embodiment, and may be appropriately changed according to design specifications and installation environments.

[0258] For example, in the above-described embodiment, the front surface portion 822 a of the first cooling unit body portion 82 (heat pipe holding portion 822 ) is interposed between the heat pipe 83 and the high-heat-generating electrical component 65 . In this regard, by avoiding direct contact with the high-heat-generating electrical components 65, deformation, damage, deterioration, corrosion, etc. of the heat pipe are suppressed. 65 is provided with an intervening object to avoid direct contact between the two. However, as long as the effect shown in the above (9-1) can be realized (the heat pipe 83 is shielded by the space outside the distribution box 50, thereby suppressing the effect of the weather resistance of the heat pipe 83), the heat ...

[0280] In the above-mentioned embodiments, the high-heat-generating electrical component 65 is described as an example of a power module including a plurality of power devices. However, the high heat generating electrical component 65 is not limited thereto, and any electrical component may be used as long as it generates heat when energized.

Abstract

Provided is an outdoor unit of a refrigeration device in which deterioration of reliability in relation to cooling of a heat-generating component using a heat pipe is suppressed. An outdoor unit (10)includes an outdoor fan (18) for generating an outdoor airflow (AF), an outdoor unit casing (40), a high-heat-generating electrical component (65), a compressor control board (76) on which the high-heat-generating electrical component (65) is mounted, an electrical component box (50) for housing the compressor control board (76), and a first cooling unit (80) for cooling the high-heat-generating electrical component (65). The first cooling unit (80) has a heat pipe (83), a plurality of first cooling unit fins (81) disposed on a flow path of the outdoor airflow (AF), and a first cooling unit main body part (82) interposed between the heat pipe (83) and the first cooling unit fins (81) and thermally connecting the heat pipe (83) and the first cooling unit fins (81). The heat pipe (83) is located in the electrical component box (50) and positioned adjacent to the high-heat-generating electrical component (65).

Description

technical field [0001] The present invention relates to refrigerator outdoor units. Background technique [0002] Conventionally, on the refrigerator outdoor unit, the air flow generated by the fan cools the electrical parts (heat generating parts) that generate heat when energized. But on the other hand, power devices such as IGBT (Insulated Gate Bipolar Transistor) or power modules including such power devices generate a particularly large amount of heat compared with other heat-generating components, and it is difficult to ensure reliability only by airflow cooling, nor can it Let cool well. Therefore, in order to increase the cooling capacity of these heat-generating components, for example, the outdoor unit of an air-conditioning unit disclosed in Patent Document 1 (JP-A-2006-266547) is cooled by a heat pipe equipped with a cooling material. In Patent Document 1, a heat pipe is thermally connected to a heat-generating component and a heat dissipation fin, and the heat...
