Problems solved by technology

Therefore, there is a problem that when the position where the vehicle transformer sucks the running wind is set in a stagnation area according to the arrangement of the peripheral equipment and the vehicle transformer, the running wind with a sufficient flow velocity cannot be sufficiently sucked into the cooler of the vehicle transformer. The surrounding area cannot obtain sufficient cooling performance by using the running wind

Embodiment approach 1

[0032] figure 1 It is a plan view showing an example of a railway vehicle in which the vehicle transformer 10 a according to Embodiment 1 of the present invention is installed on the roof of a car roof. figure 2 yes figure 1 Side view of the rail vehicle shown.

[0033] In the following description, the vehicle longitudinal direction, which is the direction in which the vehicle moves, is defined as the X direction, the vehicle width direction is defined as the Y direction, and the vehicle height direction is defined as the Z direction. The vehicle travel direction is the -X direction, the direction from left to right when facing the vehicle travel direction is the +Y direction, and the direction from the floor to the carport is the +Z direction.

[0034] Such as figure 1 and figure 2 As shown, a vehicle transformer 10 a and a plurality of peripheral devices 3 are installed on a roof 2 of a vehicle 1 . Two peripheral devices 3 are provided in front of the vehicle transfo...

Embodiment approach 2

[0066] Figure 11 It is a plan view showing the configuration of a vehicle transformer 10 b according to Embodiment 2 of the present invention. and image 3 The vehicle transformer 10 a according to Embodiment 1 shown differs in that auxiliary machines such as an oil pump 13 and an oil conservator 15 are arranged between the pipe 16 a and the transformer main body 12 and between the pipe 16 b and the transformer main body 12 . The cooler 14b has a longer structure in the X direction than the cooler 14a of the first embodiment. This is because the cover 37 a for covering the oil pump 13 and the cover 37 b for covering the oil conservator 15 are provided between the pipes 16 a and 16 b and the transformer main body 12 . Hereinafter, the same reference numerals are assigned to the same or corresponding configurations as those of the vehicle transformer 10a according to Embodiment 1, and detailed descriptions of these configurations will be omitted.

[0067] Figure 12 It is a...

Abstract

There is obtained a transformer for a vehicle that reduces the position where traveling wind is sucked into a stagnation area behind peripheral equipment in the direction of vehicle travel, thereby efficiently cooling by the traveling wind. The vehicle transformer (10a) of the present invention includes: a transformer main body (12) having a winding (9) connected to a pipe (11) for circulating the refrigerant; an oil pump (13) that circulates the refrigerant through the pipe (11 ); the cooler (14a), which is connected to the pipe (11), cools the refrigerant; and the first pipe, which is arranged behind the traveling direction of the vehicle relative to the transformer main body (12) and the cooler (14a). , and has a first air intake, a first air delivery port, and a first connecting portion, the first air intake intakes the running wind generated by the running of the vehicle, and the first air delivery port blows the running wind as cooling air toward the cooler , the first connecting portion connects the first air intake port and the first air supply port, and guides the traveling wind so that the blowing direction is opposite to the traveling direction of the vehicle, and discharges the guided traveling wind as cooling air from the first air supply port.

Description

technical field [0001] The present invention relates to a transformer for a vehicle, and more particularly, to a transformer for a vehicle that cools refrigerating oil using running wind generated by the running of the vehicle. Background technique [0002] Equipment such as air conditioners, power converters, controllers, and transformers installed in vehicles generate a lot of heat during operation. As cooling methods for these devices, there are a forced air cooling method using an electric blower, and a running wind self-cooling method using running wind generated by the running of the vehicle. [0003] The running wind self-cooling method has become popular in recent years from the viewpoint of energy saving and low noise compared with the forced air cooling method. In general, a running wind self-cooling method is used as a cooling method for equipment such as a vehicle transformer installed under the floor (for example, refer to Patent Document 1). The reason is tha...
