DRIVE UNIT, LIQUID EJECTING HEAD UNIT, AND LIQUID EJECTING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18476404 titled 'DRIVE UNIT, LIQUID EJECTING HEAD UNIT, AND LIQUID EJECTING APPARATUS

Simplified Explanation

The abstract describes a patent application for a drive unit that includes a water cooling mechanism for a liquid ejecting head unit. The drive unit generates a drive signal for the head unit and includes a drive board, a thermal conductive material, a water cooling mechanism, a pump, and a control circuit.

  • The drive unit generates a drive signal for a liquid ejecting head unit.
  • The drive unit includes a drive board with a drive circuit mounted on it.
  • A thermal conductive material is in contact with the drive circuit on the opposite side of the drive board.
  • A water cooling mechanism is in contact with the thermal conductive material.
  • A pump causes liquid in the water cooling mechanism to flow.
  • A control circuit controls the operation of the pump, switching the direction of liquid flow between forward and reverse.

Potential Applications

This technology could be applied in industrial printing systems, medical devices, and 3D printing machines.

Problems Solved

This technology helps in maintaining the optimal operating temperature of the drive circuit, preventing overheating and potential damage.

Benefits

The use of water cooling allows for efficient heat dissipation, leading to improved performance and longevity of the drive unit.

Potential Commercial Applications

Potential commercial applications include large-scale printing companies, medical equipment manufacturers, and additive manufacturing businesses.

Possible Prior Art

One possible prior art could be the use of air cooling systems in similar drive units for liquid ejecting head units.

Unanswered Questions

How does the control circuit determine when to switch the direction of liquid flow?

The control circuit likely monitors the temperature of the drive circuit to determine when to switch the direction of liquid flow.

What is the expected lifespan of the water cooling mechanism in this drive unit?

The expected lifespan of the water cooling mechanism would depend on factors such as the quality of materials used and the frequency of operation. Regular maintenance and monitoring would be necessary to ensure longevity.


Original Abstract Submitted

A drive unit is configured to generate a drive signal for driving a liquid ejecting head unit. The drive unit includes a drive board on which a drive circuit configured to generate the drive signal is mounted; a thermal conductive material that is in contact with the drive circuit on an opposite side in relation to the drive board; a water cooling mechanism that is in contact with the thermal conductive material on an opposite side in relation to the drive circuit; a pump that causes liquid in the water cooling mechanism to flow; and a control circuit that controls operation of the pump. The control circuit switches a direction in which the pump causes the liquid to flow between a forward direction and a reverse direction that is an opposite of the forward direction.
