Heat exchanger of data processing unit in communication device and its heat exchange control method

Abstract

The invention discloses a heat exchange device and a heat exchange method for electronic equipment, wherein the heat exchange device includes a working state detection unit, a control unit based on the working state and at least one heat exchange unit, and the method is: according to the electronic equipment and / or The operating state parameters of each unit control the operating state of the electronic equipment and / or the heat exchange unit corresponding to each unit. The invention not only effectively solves the disadvantages of high power consumption, high noise and short service life in the use process of the conventional constant speed heat sink, but also overcomes the high operating cost and slow response speed of the heat sink in the use process of the existing variable speed heat sink. The disadvantage of not being able to reduce the ambient temperature in a timely and effective manner. The operation state of the heat exchange unit can be adjusted and controlled at any time according to the needs, not only the response is fast and accurate, the heat dissipation effect is good, but also no need to add any auxiliary equipment, which reduces the manufacturing cost of the product.

Description

technical field [0001] The invention relates to the electronic field, in particular to a heat exchange device for data processing components in communication equipment and a heat exchange control method thereof. Background technique [0002] In the application process of electronic equipment, in order to ensure the normal operation of the electronic equipment, it is usually necessary to adopt corresponding heat dissipation means for the electronic equipment to dissipate heat, so that the normal working performance of the electronic equipment will not be affected by excessive temperature. [0003] At present, there are mainly two heat dissipation methods for electronic equipment: one is natural heat dissipation, which realizes heat dissipation through natural convection between hot and cold air; the other is forced heat dissipation, which uses some means of forced heat dissipation to dissipate heat. The fan blows the air flow to take away the heat in the electronic equipment,...

AI Technical Summary

Problems solved by technology

In the DSLAM equipment, a large number of sensor devices will be installed, which will cause the structure of the DSLAM equipment to be complicated and the cost will increase

[0009] In addition, due to the uneven heat generation inside some boards, the temperature inside some boards has even exceeded the limit temperature when the temperature difference between the top and the bottom does not increase significantly, and the speed of the variable speed fan has not been adjusted in time. To meet the purpose of automatically adapting to the heat dissipation needs of the single board

[0010] Therefore, there are still corresponding shortcomings in the implementation scheme of variable speed fan cooling provided by the prior art
