Patent ID: 8701430

Claim:
A trailer refrigeration unit that has a refrigeration unit body containing a refrigerant circuit operable in a vapor compression refrigeration cycle and an engine for driving a compressor of the refrigerant circuit and is configured to cool the interior of a trailer, the refrigeration unit body having a condensation side passage formed therein from a front surface to a top of the refrigeration unit body to allow air exchanging heat with a condenser of the refrigerant circuit to flow, the condensation side passage being configured so that the air having flowed through the condenser then flows through a radiator for the engine wherein, the radiator is disposed at the top of the refrigeration unit body, the refrigeration unit body has an evaporation side passage formed therein to allow air exchanging heat with an evaporator of the refrigerant circuit to flow, and a partition plate separating the condensation side passage from the evaporation side passage in a front to hack direction thereof, the partition plate being formed in a three-dimensional shape according to air flows in the condenser and the evaporator, and the partition plate has fan accommodation parts formed alternately concavely and convexly in a width direction of the refrigeration unit body, and, a condenser fan for the condenser in the condensation side passage and an evaporator fan for the evaporator in the evaporation side passage are arranged in a width direction of the refrigeration unit body.
