Abstract

An ink jet apparatus includes: a head that discharges liquid; a circuit substrate that has a drive circuit for driving the head; a heat sink which has a part that is in direct or indirect contact with the circuit substrate and is able to dissipate heat generated in the circuit substrate; and a fan that generates air flow capable of cooling the heat sink. The heat sink is configured such that the air flow is not directly blown against the drive circuit and such that the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.

Claims (11)

1. An ink jet apparatus, comprising:

a head that discharges liquid;

a circuit substrate that has a drive circuit that is configured to drive the head;

a cover frame supporting the circuit substrate inside of the cover frame, the cover frame having a through hole;

a heat sink which has a part that is in direct or indirect contact with the circuit substrate and is configured to dissipate heat generated in the circuit substrate, the heat sink being disposed inside of the cover frame; and

a fan that generates air flow to cool the heat sink, the fan being arranged such that the fan and the heat sink face to each other via the through hole, the fan being disposed to face the drive circuit,

the heat sink being disposed between the drive circuit and the fan, and

the heat sink being configured such that the air flow is not directly blown against the drive circuit and such that the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.

2. The ink jet apparatus according to claim 1 , further comprising a collection section configured to collect mist adhered to the heat sink.

3. The ink jet apparatus according to claim 2 , wherein

the collection section is attached to the cover frame such that the collection section does not overlap the heat sink as viewed in a direction in which the fan and the heat sink face to each other.
