Description

本発明は、強制空冷方式を用いた通信装置に関する。   The present invention relates to a communication device using a forced air cooling system.

通信装置においては、処理能力の大容量化および高密度実装化により、単位面積当たりの消費電力が増大することで装置内部の温度上昇が顕著となっている。このため、周囲環境温度によらず使用部品の信頼性を確保するために、自然空冷方式から強制空冷方式へと移行している。   In communication devices, the increase in processing capacity and density mounting have resulted in a significant increase in temperature inside the device due to an increase in power consumption per unit area. For this reason, in order to ensure the reliability of the components used regardless of the ambient temperature, the natural air cooling method is shifted to the forced air cooling method.

強制空冷方式を採用することで、単位面積当たりの許容消費電力を高めることができるため、高密度実装が可能となり、処理能力あたりの省スペース化が進んでいる。   By adopting the forced air cooling method, the allowable power consumption per unit area can be increased, so that high-density mounting is possible and space saving per processing capacity is progressing.

そして、このような従来の強制空冷方式を用いた装置では、装置に要求される周囲温度条件下において、常に正常動作が可能な内部温度以下となるように空冷風量を算出し、実際の周囲温度に関わらず、常時算出された空冷風量を確保するようにＦＡＮを回転するようにしていた（例えば、特許文献１）。   In such a device using the conventional forced air cooling method, the air cooling air volume is calculated so that the air temperature is always below the internal temperature at which normal operation is possible under the ambient temperature conditions required for the device, and the actual ambient temperature Regardless, the FAN is rotated so as to ensure the constantly calculated amount of air cooling air (for example, Patent Document 1).

特開平１０−１５８５５９JP-A-10-158559

上記のように、従来の強制空冷方式の装置では、実際の周囲温度に関わらず予め算出した最悪環境下で必要な空冷風量を常時確保するようにＦＡＮを回転させており、平均的な環境温度下では過剰な風量での空冷を実施しているという問題点があった。   As described above, in the conventional forced air cooling system, the FAN is rotated so as to always secure the necessary air cooling air volume in the worst environment calculated in advance regardless of the actual ambient temperature, and the average ambient temperature Below, there was a problem that air cooling was carried out with excessive air volume.

本発明は、上記の課題を解決するためになされたものであり、本発明の空冷通信装置は、内部を強制空冷する装置であって、前記強制空冷に使用する風を当該装置内部へ送出するＦＡＮ部と、このＦＡＮ部の空気温度を観測し、温度情報として出力する温度検出部と、前記温度情報と予め設定された目標温度とを比較し、比較結果に基づいて前記ＦＡＮ部の風の送出状態を制御するＦＡＮ制御部とを備える。   The present invention has been made to solve the above problems, and the air-cooled communication device of the present invention is a device for forcibly air-cooling the inside, and sends the wind used for the forced air-cooling to the inside of the device. The FAN unit, the temperature detection unit that observes the air temperature of the FAN unit, outputs the temperature information, compares the temperature information with a preset target temperature, and based on the comparison result, the wind of the FAN unit And a FAN control unit for controlling the sending state.

本発明によれば、ＦＡＮ部の風の送出状態を制御することで、装置内部温度を一定とし、安定動作を図ることが可能となる。また、ＦＡＮ部の空気温度を観測し周囲温度変化に対応した風の送出状態に制御することで、ＦＡＮの無駄な動作を防止することが可能となり、低消費電力化、低騒音化を実現する。   According to the present invention, by controlling the wind sending state of the FAN unit, it is possible to keep the temperature inside the apparatus constant and to achieve stable operation. In addition, by observing the air temperature in the FAN section and controlling it to a wind sending state corresponding to changes in the ambient temperature, it becomes possible to prevent unnecessary operation of the FAN, realizing low power consumption and low noise. .

The temperature detectors 4-1 to 4-n + 1 detect and digitize the temperature of air passing through the FANs 3-1 to 3-n + 1 of the same system. The rotation speed control units 5-1 to 5-n + 1 have preset target temperatures, respectively, and the air temperature information and the target temperature obtained from the temperature detection units 4-1 to 4-n + 1 of the same system, respectively. Based on this, the rotational speed of the FANs 3-1 to 3-n + 1 of the same system is controlled.

ＦＡＮ部２−１〜２−ｎ＋１は、それぞれ同系統のＦＡＮ３−１〜３−ｎ＋１、温度検出部４−１〜４−ｎ＋１、回転数制御部５−１〜５−ｎ＋１により構成され、通信装置１を強制空冷する機能を有する。本通信装置１においては、ｎ＋１（ｎは正の整数）個で構成され、一つのＦＡＮ部が故障した場合でも、規定周囲温度内での運用に耐えられるよう、通信装置１内の温度上昇を抑えることの可能な使用数及び最大回転数が規定される。   The FAN units 2-1 to 2-n + 1 are configured by FANs 3-1 to 3-n + 1, temperature detection units 4-1 to 4-n + 1, and rotation speed control units 5-1 to 5-n + 1 of the same system, respectively, It has a function of forcibly air-cooling the device 1.

It transfers to the rotation speed control part 5-1. The rotation speed control unit 5-1 compares the air temperature information transferred from the temperature detection unit 4-1 with a preset target temperature, and calculates the set target temperature to the FAN 3-1.

FIG. 2 is a configuration diagram of the air-cooled communication device according to the first embodiment of the present invention. In the figure, a communication device 1 which is an air-cooled communication device includes FAN units 2-1 to 2-n + 1 from the first system to the (n + 1) th system, and FAN3-1 from the first system to the (n + 1) th system constituting the FAN unit. ˜3-n + 1, temperature detection units 4-1 to 4-n + 1 from the first system to the (n + 1) th system, and a rotation speed control unit (FAN control unit) 6 from the first system to the (n + 1) th system.

ＦＡＮ３−１〜３−ｎ＋１は、通信装置１内に風速を与えるために風を送出する。温度検出部４−１〜４−ｎ＋１は、それぞれ同系統の前記ＦＡＮ３−１〜３−ｎ＋１内を通過する空気温度を検出し数値化する。回転数制御部６は、予め設定された目標温度を有し、前記温度検出部４−１〜４−ｎ＋１より得られた空気温度情報と前記目標温度に基づいて、前記ＦＡＮ３−１〜３−ｎ＋１の回転数を制御する。   The FANs 3-1 to 3-n + 1 send wind in order to give wind speed to the communication device 1. The temperature detectors 4-1 to 4-n + 1 detect and digitize the temperature of air passing through the FANs 3-1 to 3-n + 1 of the same system.

ＦＡＮ部２−１〜２−ｎ＋１は、それぞれ同系統のＦＡＮ３−１〜３−ｎ＋１、温度検出部４−１〜４−ｎ＋１により構成され、通信装置１を強制空冷する機能を有する。本通信装置１においては、ｎ＋１（ｎは正の整数）個で構成され、一つのＦＡＮ部が故障した場合でも、規定周囲温度内での運用に耐えられるよう、通信装置１内の温度上昇を抑えることの可能な使用数及び最大回転数が規定される。   The FAN units 2-1 to 2-n + 1 are composed of FANs 3-1 to 3-n + 1 and temperature detection units 4-1 to 4-n + 1 of the same system, respectively, and have a function of forcibly air-cooling the communication device 1. This communication device 1 is composed of n + 1 (n is a positive integer), and even if one FAN unit fails, the temperature increase in the communication device 1 can be maintained so that it can withstand operation within the specified ambient temperature. The number of uses and the maximum number of rotations that can be suppressed are defined.

次に動作を説明する。各ＦＡＮ部２−１〜２−ｎ＋１において、温度検出部４−１〜４−ｎ＋１それぞれが、同系統のＦＡＮ部２−１〜２−ｎ＋１内の空気温度（例えば、同系統のＦＡＮを通過する空気温度）を観測し、得られた空気温度情報を回転数制御部６へ転送する。回転数制御部６は、温度検出部４−１〜４−ｎ＋１より転送されてきた空気温度情報と予め設定された目標温度とを比較演算し、設定された目標温度となるように各ＦＡＮ３−１〜３−ｎ＋１に対して回転数制御情報を送出し回転数を制御する。   Next, the operation will be described. In each of the FAN units 2-1 to 2-n + 1, each of the temperature detection units 4-1 to 4-n + 1 passes through the air temperature in the FAN units 2-1 to 2-n + 1 of the same system (for example, passes through the FAN of the same system). And the obtained air temperature information is transferred to the rotation speed control unit 6. The rotation speed controller 6 compares the air temperature information transferred from the temperature detectors 4-1 to 4 -n + 1 and a preset target temperature, and calculates each FAN 3-3 so that the set target temperature is reached. Rotational speed control information is sent to 1-3-n + 1 to control the rotational speed.

尚、回転数制御部６の回転数制御方法としては、各系統のＦＡＮ毎に目標温度となるように回転数を制御する方法と、各系統全ての空気温度情報が目標温度以下となるように、同一回転数を全てのＦＡＮ３−１〜３−１ｎ＋１に設定する方法がある。また、予め設定された目標温度となるように連続的に回転数制御を実施する方法、若しくは、目標温度を１つまたは複数個有し、各目標温度を超える度に回転数を段階的に上げていくステップ式の制御方法などが実施可能である。   In addition, as a rotational speed control method of the rotational speed control unit 6, a method of controlling the rotational speed so as to be a target temperature for each FAN of each system, and so that air temperature information of all the systems is below the target temperature. There is a method of setting the same rotational speed to all the FANs 3-1 to 3-1n + 1. Also, a method for continuously controlling the rotational speed so as to achieve a preset target temperature, or one or a plurality of target temperatures, and each time the target temperature is exceeded, the rotational speed is increased stepwise.

当該制御により、全てのＦＡＮ３−１〜３−ｎ＋１の最大回転数が必要となる状態は、ＦＡＮ部２−１〜２−ｎ＋１のいずれか一つのＦＡＮ部が故障し、かつ通信装置１の周囲温度が規定された最大周囲温度となった場合のみとなる。前述の最悪環境以外の場合には、ＦＡＮ３−１〜３−ｎ＋１の回転数が過剰にならないような最適制御を行うことで、低消費電力化、低騒音化が可能となる。   The state in which the maximum number of rotations of all the FANs 3-1 to 3-n + 1 is required by the control is that any one of the FAN units 2-1 to 2-n + 1 has failed and the surroundings of the communication device 1 Only when the temperature reaches the specified maximum ambient temperature. In cases other than the above-mentioned worst environment, it is possible to reduce power consumption and noise by performing optimal control so that the rotation speeds of FANs 3-1 to 3-n + 1 do not become excessive.
