TECHNICAL FIELD

The present disclosure relates to a vehicle power conversion apparatus.

BACKGROUND ART

Some existing vehicle power conversion apparatuses have been known, in which heat transferred from a semiconductor element is cooled by introduction of traveling wind generated due to running of a vehicle to a heat radiator, which is disposed on the surface opposite to the surface provided with a heat receiver on which the semiconductor element is mounted (for example, refer to Patent Literature 1).

SUMMARY OF INVENTION

Technical Problem

Unfortunately, the existing vehicle power conversion apparatuses cannot achieve introduction of sufficient traveling wind to the heat radiator, leading to impairment in cooling capacity, in the case where the heat radiator is disposed at an inner position relative to a rigging limit.

The present disclosure is made in view of the above-described circumstances, and an objective of the present disclosure is to provide a vehicle power conversion apparatus capable of efficient introduction of traveling wind, leading to improvement in cooling capacity.

Solution to Problem

In order to achieve the aforementioned objective, a vehicle power conversion apparatus according to the present disclosure includes: a housing to be attached to a vehicle; a cooler including a heat receiver that is disposed on the side near the housing and has a heated surface provided with a semiconductor element, and a heat radiator disposed on the surface of the heat receiver opposite to the heated surface; and a position adjusting member to adjust the position of the end of the heat radiator distant from the housing in the direction approaching the rigging limit of the vehicle.

Advantageous Effects of Invention

The vehicle power conversion apparatus according to the present disclosure includes the cooler including the heat receiver that is disposed on the side near the housing to be attached to the vehicle and has the heated surface provided with the semiconductor elements, and the heat radiator disposed on the surface of the heat receiver opposite to the heated surface, and the position adjusting member to adjust the position of the end of the heat radiator distant from the housing in the direction approaching the rigging limit of the vehicle. The vehicle power conversion apparatus can therefore achieve efficient introduction of traveling wind, leading to improvement in cooling capacity.
