Abstract
The utility model discloses an air cooling device of a thermal print head, which mainly comprises an aluminum substrate, wherein one side of the aluminum substrate is provided with a print head, the aluminum substrate is hollow, two air channels are arranged in the aluminum substrate, and air inlet holes are arranged at the middle part of the other side of the aluminum substrate, two ends of the aluminum substrate are respectively provided with a first air outlet hole and a second air outlet, hole the first air outlet hole is provided with a first axial fan, and the second air outlet hole is provided with a second axial fan. At least two oval air inlet holes are adopted. The first and the second air outlet holes are round. The technical scheme is as follows: the air inlet holes are arranged in the middle of the aluminum substrate, the working mode of supplying air from the middle part is adopted, the heat can be rapidly exhausted through the axial fans, thereby prolonging the service life of the print head and improving the quality of printing. As the thermal print head adopts a mode of air cooling, the defect that electronic elements such as the print head and the like are burnt down due to water leakage is prevented, and at the same time, a cooling water pump is unnecessary to be equipped externally, so that the air cooling device of the thermal print head can save energy and has smaller noise.
Description
Technical field:
The utility model relates to a kind of printer cooling device, relates in particular to a kind of thermal printing head air cooling equipment.
Background technology:
The domestic existing scroll machine printhead type of cooling is traditional water-cooling pattern, mainly has following problem:
1, must outer join a water pump and water tank during water-cooled, noise is big during work, causes environmental pollution.2, the long sealing of life period easily goes wrong during water-cooled, thereby causing that printhead leaks to burn prints first-class electric elements.3, the big and bad control of printhead temperature of energy consumption exists the water inlet end temperature low, and shortcomings such as water side temperature height cause print head longevity short, improve the printer use cost.
The utility model content:
In view of this, the purpose of this utility model provides a kind of thermal printing head air cooling equipment.
The technical solution of the utility model realizes in the following manner:
A kind of thermal printing head air cooling equipment, mainly comprise aluminium base, aluminium base one side is provided with printhead, wherein, aluminium base is a hollow structure, and inside is provided with two air channels, the opposite side medium position of aluminium base is provided with fresh air inlet, two ends are respectively equipped with first exhaust vent and second exhaust vent, and first exhaust vent is provided with first aerofoil fan, and second exhaust vent is provided with second aerofoil fan.
Fresh air inlet is oval, is at least two.
First exhaust vent and second exhaust vent are circle.
Good effect of the present utility model is:
The technical solution of the utility model is owing to be arranged at the aluminium base medium position with fresh air inlet, adopt the mode of operation of middle part air intake, heat can be discharged rapidly by aerofoil fan rapidly, again by being arranged on temperature inductor wherein, intensification situation with each position of printhead passes to master control borad rapidly, regulate the rotating speed of two end axles flow fan by master control borad, thereby guarantee the uniformity of each position temperature of printhead, thereby prolonged the life-span of printhead and improved print quality.
Because thermal printing head adopts the air-cooled type of cooling, stopped to burn the drawback of the first-class electronic devices and components of printing because of leaking.Do not join cooling water pump outside not needing simultaneously, more energy-conservation, noise is littler.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
By Fig. 1 and Fig. 2 as can be seen, this thermal printing head air cooling equipment, mainly comprise aluminium base 6, aluminium base 6 one sides are provided with printhead 5, wherein, aluminium base 6 is a hollow structure, inside is provided with two air channels 3, and the opposite side medium position of aluminium base 6 is provided with fresh air inlet 2, and two ends are respectively equipped with first exhaust vent 7 and second exhaust vent 8, first exhaust vent 7 is provided with first aerofoil fan, 1, the second exhaust vent 8 and is provided with second aerofoil fan 4.
It can also be seen that by Fig. 2 fresh air inlet 2 is two slotted eyes.
It can also be seen that by Fig. 2 first exhaust vent 7 and second exhaust vent 8 are circle.
When printhead is worked, printhead produces work calories, pass to the aluminium base of its cooling effect by heat, inside at the aluminium base of printhead is provided with two cooling air channels, and have air inlet at the aluminium base medium position, install first aerofoil fan and second aerofoil fan additional in air outlet position, aluminium base two ends, under the acting in conjunction of first aerofoil fan and second aerofoil fan, in two cooling air channels, form negative pressure, thereby make normal temperature air enter cooling air channel, be divided into two-way then and discharge by first aerofoil fan 1 and second aerofoil fan 4 from first air outlet 7 and second exhaust vent 8 from fresh air inlet.
