Abstract

(57) [Summary] [Structure] The outside air flows through the element 4 which constitutes the inside of the panel cooler 2 attached to the upper portion of the rotating electric machine body 1. Further, the inside air flows through the rotating electric machine body 1 and the panel cooler 2. At that time, there is no partition inside the panel cooler 2. [Effect] The average flow velocity of the inside air can be increased, and the effective cross-sectional area of ventilation can be increased to improve the cooling performance of the cooler.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a panel cooler for rotating electric machines.

[0002]

[Prior Art]

 An example of the prior art is shown in FIGS. 2 is an overall view of the rotating electric machine, and FIG. 3 is a panel cooler sectional view. Reference numeral 1 is a rotating electric machine main body, 2 is a panel cooler attached to the upper portion of the rotating electric machine main body 1, 3 and 4 are partition plates and elements that constitute the inside of the panel cooler 2, and 5 is this partition plate 3, element. It is a cooler cover that stores 4.

Next, the operation will be described. The inside air circulates inside the panel cooler 2 partitioned by the rotary electric machine main body 1 and the partition plate 3 by the fan mounted inside the rotary electric machine main body 1. Further, the outside air is sucked in by another fan mounted inside the rotary electric machine 1 and is discharged to the outside through the inside of the element 4 inside the panel cooler 2. The structure of the partition plate 3 forming the inside of the panel cooler 2 will be additionally described. As shown in FIG. 3, the partition plate 3 divides the panel cooler into four parts, and the inside air has a structure in which two parts of the four parts are parallel to each other.

[0004]

[Problems to be solved by the device]

 Since the conventional partition plate structure of a panel cooler for rotating electrical machines is configured as described above, when the inside air flows, it has to join and split in the middle, and the average flow velocity becomes slow. Further, due to the above, there is a problem that the effective cross-sectional area (the cross-sectional area through which the inside air flows) becomes small and the cooling performance of the cooler deteriorates.

The present invention has been made to solve the above problems, and an object thereof is to improve the cooling performance of a cooler by increasing the average flow velocity of the inside air and increasing the effective cross-sectional area of ventilation. To do.

[0006]

[Means for Solving the Problems]

 The structure of the panel cooler according to the present invention eliminates the partition plate.

[0007]

[Action]

 In the structure of the panel cooler in this invention, by eliminating the partition plate, the average flow velocity of the inside air becomes faster, the effective cross-sectional area of ventilation increases, and the cooling performance of the cooler improves.

[0008]

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of the panel cooler. Since the numbers and names are the same as the conventional ones, the description is omitted.

Next, the operation will be described. The inside air circulates inside the rotary electric machine 1 and the panel cooler 2 by a fan mounted inside the rotary electric machine 1. In addition, the outside air is sucked in by another fan mounted inside the rotary electric machine 1 and is discharged to the outside through the inside of the element 4 inside the panel cooler 2. There is no partition plate in the middle of the flow of the internal air circulating inside the panel cooler 2.

[0010]

[Effect of the device]

 As described above, according to the present invention, since the partition plate of the panel cooler is eliminated, the average air flow velocity is increased without the confluence and splitting of the inside air, and the effective ventilation area is increased to improve the cooling performance of the cooler. ..
