With the rapid development of the application of the industrial wide-format ink-jet printing technology in different scenes, the requirements of end users on the quality and the efficiency of printing are higher and higher. This indirectly increases the difficulty of hardware design to implement these printing functions; such as: control card overall dimension and heat dissipation problem, drive a plurality of (more than 4) inkjet printheads (hereinafter abbreviated as: shower nozzle), handle print data performance promotion etc..

The heat generated by the components which are easy to generate heat on the control card has a certain destructive effect on the whole system, and influences the working stability of the whole printing equipment even damages the control card when serious. It is necessary to control the temperature of the control card reasonably.

As shown in fig. 1 and 2, in the aspect of heat dissipation of the control card, the prior art design mainly adopts a heat dissipation mode of adding a plurality of fans to assist in heat dissipation. A, an industrial printer core control card module (simply called a control card); b, a radiator 1; c, a radiator 2; d, a heat radiation fan 1; e, a heat radiation fan 2; and f, controlling mechanical mounting holes of the card. The radiator 1 and the radiator 2 represent two specifications of radiators (different external dimensions and materials); the heat radiation fan 1 and the heat radiation fan 2 also represent auxiliary heat radiation fans of two specifications.

The radiator is fixed on the control card through a welding mode or an M3 screw, the fan is arranged on the radiator, and the control card is required to provide a fan driving interface; in addition, the design of the scheme needs to additionally increase a temperature sensor, samples the temperature of the radiator in real time, and when the temperature rises to a certain value (about 50 ℃), the fan starts to work to assist in heat dissipation.

The defect of the heat radiation structure of the existing printer control card is that: 1) The radiator has a plurality of specifications, increases section bar mould cost. 2) The fan has a plurality of specifications, increases designer's work load. 3) The additional fan drive interface increases the cost of control card design and manufacturing. 4) The extra sensor samples temperature, increasing the material cost of the control card. 5) The radiator and the auxiliary radiating modes of a plurality of fans increase the overall dimension of the control card, so that the printing equipment is not compact in structure. 6) The fans are affected by external dust, need to be cleaned regularly, and need to consider life problems.

It should be noted that the foregoing description of the background art is only for the purpose of providing a clear and complete description of the technical solution of the present utility model and is presented for the convenience of understanding by those skilled in the art. The above-described solutions are not considered to be known to the person skilled in the art simply because they are set forth in the background of the utility model section.
