example 2

[0254] In the above-described embodiment, the first cooling unit body portion 82 (the fin holding portion 821 ) has an area larger than that of the first opening 52 a when viewed from the front or back (when viewed from the front-rear direction), and is provided accordingly. In order to block the 1st opening 52a, the space outside the distribution box 50 is divided into the internal space SP. 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 air flow 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 is not contradictory, the first cooling The configuration of the unit body portion 82...

[0257] The configuration of the first cooling unit 80 is not limited to that shown in the above-described embodiment, and can 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 (the 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 pipes are suppressed. An intervening object is set between 65 to avoid direct contact between the two. However, as long as the effect shown in (9-1) above can be achieved (the heat pipe 83 is shielded by the space outside the distribution box 50 and the weather resistance of the heat pipe 83 is suppressed from being lowered), the heat pipe 83 and ...

[0280] In the above-mentioned embodiment, 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 to this, and any electrical component that generates heat when energized may be used.

Abstract

Provided is an outdoor unit for a refrigerator that cools heat-generating components using a heat pipe and can suppress a reduction in reliability. The outdoor unit (10) is provided with: an outdoor fan (18) that generates an outdoor air flow (AF); an outdoor unit housing (40); a high-heat-generating electrical component (65); 76); a power distribution box (50) for accommodating a compressor control board (76); and a first cooling unit (80) for cooling high-heat-generating electrical components (65). The first cooling unit (80) has: a heat pipe (83); a plurality of first cooling unit fins (81) arranged on the flow path of the outdoor airflow (AF); and a heat pipe (83) and the first cooling unit interposed therebetween Between the fins (81), the first cooling unit body part (82) thermally connects the heat pipe (83) and the first cooling unit fins (81). The heat pipe (83) is located in the distribution box (50), adjacent to the high-heating electrical component (65).

Description

technical field [0001] The present invention relates to refrigerator outdoor units. Background technique [0002] Conventionally, on a refrigerator outdoor unit, the air flow generated by a fan cools electrical components (heat-generating components) that generate heat when energized. On the other hand, power devices such as IGBTs (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 by cooling only by air flow. Cool down sufficiently. Therefore, in order to increase the cooling capacity of these heat-generating components, for example, the outdoor unit of the air conditioner shown in Patent Document 1 (Japanese Unexamined Patent Publication No. 2006-266547 ) is cooled by a heat pipe provided with a cooling material. In Patent Document 1, a heat pipe is thermally connected to a heat generating member and a heat d...
