Description

Dip angle PTC dummy load

Technical Field

The utility model relates to a power supply test equipment, specifically speaking are inclination PTC formula dummy load belongs to power supply test equipment field.

Background

The dummy load is a device for testing power supply of a data center, the dummy load uses a machine room power supply to generate heat through an internal resistor and uses an internal fan to generate airflow for heat dissipation, and for example, the dummy load testing system and the dummy load testing device are disclosed in the Chinese utility model patent with the application number of CN201720355461. X. A dummy load 02 as used in the data center room of fig. 1 is mounted inside the cabinet 01. As shown in fig. 2, the PTC (thermistor) 03 inside the dummy load currently used in the data center is arranged in parallel with the fan 04, and when the power of a single dummy load needs to be increased, the PTC (thermistor) of the conventional dummy load is increased in parallel with the fan by the number of a single row of PTC (thermistor) or by a plurality of rows of PTC (thermistor) to allow air to flow through the plurality of rows of PTC (thermistor). When the second row of PTC (thermistor) meets the high-temperature air heated by the first row of PTC (thermistor), the second row of PTC (thermistor) resistors can reduce due to the fact that effective heat dissipation power cannot be achieved, and therefore the mode of arranging the multiple rows of PTC (thermistor) resistors cannot give play to the due power of the PTC (thermistor). And the dummy load with a single row of PTC (thermal resistor) layout parallel to the fan can be provided with less PTC (thermal resistor). In summary, the upper limit of the power of the dummy load is low. In the past, when a dummy load is added with single power, the utilization rate of a newly added PTC (positive temperature coefficient) is low. How to install more PTC thermistors in the limited space of the dummy load to realize higher power of a single dummy load, thereby realizing less occupation of the internal space of the cabinet and more convenient installation and disassembly of unit test power, and becoming a remarkable requirement for achieving higher working efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to design an inclination PTC formula dummy load, with dummy load PTC and fan slope, PTC has the overall arrangement structure at certain inclination with the fan, has improved dummy load list power and newly-increased PTC utilization ratio.

The technical scheme of the utility model is that:

the device comprises an inclination angle PTC dummy load, a control unit and a control unit, wherein the dummy load is arranged in a cabinet and comprises a dummy load shell, a PTC thermistor and a fan; the PTC thermistor and the fan are arranged at a certain inclination angle.

The direction of the inclination angle may be in any direction, preferably an acute angle.

The directions of the inclination angles of the PTC thermistors are the same or different.

The PTC thermistor and the fan are both arranged in the dummy load shell.

In order to solve the existing problem, the PTC thermistors in the dummy load and the fan in the dummy load are arranged at a certain inclination angle, and more PTC thermistors can be arranged in a limited inner space of the dummy load in a single-row mode, so that the upper power limit of a single dummy load is increased, and the utilization rate of the newly-increased PTC thermistors in the dummy load is improved.

The beneficial effects of the utility model are that: the PTC thermistors in the dummy load and the fan in the dummy load are arranged at a certain inclination angle, so that more PTC thermistors can be arranged in the limited inner space of the dummy load, the power of a single dummy load is improved, and the newly added dummy load can not run at low power.

The present invention will be further explained with reference to the drawings and examples.

Detailed Description

The following description is provided to illustrate the preferred embodiments of the present invention, and it is to be understood that the preferred embodiments described herein are provided for illustration and explanation purposes only and are not intended to limit the present invention.

Example 1

As shown in fig. 3 to 4, a dummy load of an inclination angle PTC type, the dummy load 2 being provided in a cabinet 01, the dummy load including a dummy load case 11, a PTC (thermistor) 12, a fan 13, a power switch 14, and the like; the PTC (thermistor) 12 is disposed at an inclination angle to the fan 13.

The inclination direction may be any direction, and is in a range of greater than (not including) 0 ° and less than (not including) 360 °, and is preferably an acute angle;

the directions of the inclinations of the respective PTCs (thermistors) are the same or different.

The PTC thermistor and the fan are both arranged in the dummy load shell.

The dummy load is disposed within the cabinet. The cabinet is a metal cabinet body with an internal mounting frame covered by an external cover plate and a door. The electronic equipment mounting bracket is used for mounting electronic equipment, generally has a cuboid shape and is placed on the ground. And the adaptive environment and safety protection are provided for the normal work of the electronic equipment.

In order to solve the existing problem, the PTC (thermistor) inside the dummy load and the fan inside the dummy load are arranged at a certain inclination angle, and more PTC (thermistors) can be arranged in a limited inner space of the dummy load in a single-row mode, so that the upper power limit of a single dummy load is increased, and the utilization rate of the newly-increased PTC (thermistors) inside the dummy load is improved.
