Abstract

The invention discloses a single board temperature control device and method, and belongs to the field of electronic communication. The device comprises a radiator, a thermistor and a temperature control module, wherein the radiator is mounted on a shell, and the thermistor is arranged on an optical module. The radiator comprises at least one thermoelectric refrigeration radiator, the thermoelectric refrigeration radiators are at least mounted on the shell positioned on an air outlet side of a single board, and the temperature control module is respectively electrically connected with the thermoelectric refrigeration radiators and the thermistor, and used for controlling the input power of the corresponding thermoelectric refrigeration radiator according to the measured value of the thermistor. The input power of the corresponding thermoelectric refrigeration radiator can be adjusted according to the temperature of the optical module, the working temperature of the optical module is effectively controlled, so that the optical module can normally work and is convenient to mount, and plugging and unplugging of the optical module are unaffected.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a single board temperature control device and method. Background technique [0002] With the development of communication technology, in order to meet the needs of improving equipment bandwidth and transmission distance and other indicators, the integration of single boards is getting higher and higher. A single board is usually equipped with multiple optical modules, such as 100G single boards. There are 10 optical modules. Because the optical module generates a lot of heat while communicating, it is necessary to dissipate heat from the board in time to control the temperature of the optical module, so as to ensure the normal operation of the device on the single board. [0003] In the prior art, the heat dissipation problem of the single board is mainly solved by cooperating with the heat dissipation fan and the heat sink. Wherein, the cooling fan is arranged on one si...
