The electric component box has an opposing plate that faces an air entrance surface of the external heat exchanger. A heat sink is provided on the opposing plate of the electric component box. The heat sink is exposed to the outside of the electric component box to cool a power module on the inverter board. ## Claims ### Claim 1 A refrigeration apparatus for transport, comprising: a condenser having an air entrance surface and an air exit surface, the condenser being configured to allow air to flow from the air entrance surface toward the air exit surface; and a box arranged on a lateral side of the condenser and houses an inverter board, wherein the box has an opposing plate that faces the air entrance surface of the condenser, and the refrigeration apparatus for transport includes a heat sink that is provided on the opposing plate and exposed to an outside of the box to cool a heat-producing component on the inverter board. ### Claim 2 (depends on 1) The refrigeration apparatus for transport of claim 1, further comprising: a duct that forms an air passage in which the heat sink is arranged. ### Claim 3 (depends on 2) The refrigeration apparatus for transport of claim 2, wherein the duct has an air inlet opening downward. ### Claim 4 (depends on 3) The refrigeration apparatus for transport of claim 3, wherein the duct has an air outlet opening toward the air entrance surface of the condenser. ### Claim 5 (depends on 4) The refrigeration apparatus for transport of claim 4, wherein the duct has a first portion having an air inlet and extending in a predetermined direction, and a second portion having an air outlet, the second portion being continuous with the first portion and extending in a direction intersecting with the predetermined direction. ### Claim 6 (depends on 3) The refrigeration apparatus for transport of claim 3, wherein the duct has a first portion having an air inlet and extending in a predetermined direction, and a second portion having an air outlet, the second portion being continuous with the first portion and extending in a direction intersecting with the predetermined direction. ### Claim 7 (depends on 3) The refrigeration apparatus for transport of claim 3, wherein the condenser has a refrigerant outlet at one end, and air that has passed through the heat sink passes near the other end of the condenser. ### Claim 8 (depends on 2) The refrigeration apparatus for transport of claim 2, wherein the duct has an air outlet opening toward the air entrance surface of the condenser. ### Claim 9 (depends on 8) The refrigeration apparatus for transport of claim 8, wherein the duct has a first portion having an air inlet and extending in a predetermined direction, and a second portion having an air outlet, the second portion being continuous with the first portion and extending in a direction intersecting with the predetermined direction. ### Claim 10 (depends on 2) The refrigeration apparatus for transport of claim 2, wherein the duct has a first portion having an air inlet and extending in a predetermined direction, and a second portion having an air outlet, the second portion being continuous with the first portion and extending in a direction intersecting with the predetermined direction. ### Claim 11 (depends on 2) The refrigeration apparatus for transport of claim 2, wherein the heat sink includes: a plate-shaped substrate having a mounting surface that makes contact with the heat-producing component; and a plurality of plate-shaped fins protruding from a surface of the substrate different from the mounting surface, and the fins divide the air passage formed by the duct into a plurality of flow paths. ### Claim 12 (depends on 11) The refrigeration apparatus for transport of claim 11, wherein the fins of the heat sink extend in an up-down direction. ### Claim 13 (depends on 2) The refrigeration apparatus for transport of claim 2, wherein the condenser has a refrigerant outlet at one end, and air that has passed through the heat sink passes near the other end of the condenser. ### Claim 14 (depends on 1) The refrigeration apparatus for transport of claim 1, further comprising: a control board that is housed in the box and controls the refrigeration apparatus for transport. ### Claim 15 (depends on 1) The refrigeration apparatus for transport of claim 1, further comprising: a reactor housed in the box and arranged above the inverter board. ### Claim 16 (depends on 1) The refrigeration apparatus for transport of claim 1, wherein the condenser has a refrigerant outlet at one end, and air that has passed through the heat sink passes near the other end of the condenser. ### Claim 17 (depends on 1) A transport container, comprising: the refrigeration apparatus for transport of claim 1; and a container body. ### Claim 18 A refrigeration apparatus for transport, comprising: a condenser having an air entrance surface and an air exit surface, the condenser being configured to allow air to flow from the air entrance surface toward the air exit surface; a box arranged on a lateral side of the condenser and houses an inverter board; a control board that is housed in the box and controls the refrigeration apparatus for transport; a divider plate provided in the box to separate a space housing the inverter board and a space housing the control board from each other and reduce noise propagation from the inverter board to the control board, wherein the box has an opposing plate that faces the air entrance surface of the condenser, and the refrigeration apparatus for transport includes a heat sink that is provided on the opposing plate and exposed to an outside of the box to cool a heat-producing component on the inverter board. ### Claim 19 (depends on 18) The refrigeration apparatus for transport of claim 18, wherein through holes are formed in upper and lower portions of the divider plate.
