1. A refrigeration device, comprising:
a refrigerator; and
a heat pipe comprising a condensation unit, a pipe unit, and an evaporation unit,
wherein the condensation unit is connected with the refrigerator such that heat exchange therewith can be performed to condense a refrigerant,
wherein the pipe unit circulates the refrigerant between the condensation unit and the evaporation unit,
wherein the evaporation unit extends along wall surfaces of a storage chamber that houses a preservation object,
wherein the evaporation unit is attached to the wall surfaces such that heat exchange therewith can be performed to evaporate the refrigerant,
wherein the evaporation unit comprises a first pipe conduit and a second pipe conduit,
wherein the first pipe conduit includes a first near-end part a first far-end part a first long circumference part, a first short circumference part, and a first junction part,
wherein the first near-end part is located closer to the condensation unit than the first far-end part,
wherein the first far-end part is located opposite to the first near-end part,
wherein the first long circumference part, the first short circumference part, and the first junction part are arranged between the first near-end part and the first far-end part,
wherein the second pipe conduit includes a second near-end part a second far-end part a second long circumference part, a second short circumference part, and a second junction part,
wherein the second near-end part is located closer to the condensation unit than the second far-end part,
wherein the second far-end part is located opposite to the second near-end part,
wherein the second long circumference part, the second short circumference part, and the second junction part are arranged between the second near-end part and the second far-end part,
wherein the first near-end part of the first pipe conduit is positioned higher than the second near-end part of the second pipe conduit,
wherein the first long circumference part is located closer to the first near-end part than the first short circumference part and the first junction part, the first short circumference part is located closer to the first far-end part than the first long circumference part and the first junction part, and the first junction part is located between the first long circumference part and the first short circumference part,
wherein the first long circumference part extends around the storage chamber from the first near-end part side toward the first far-end part side in a first circumference direction,
wherein the first long circumference part extends along more wall surfaces than the first short circumference part,
wherein the first junction part includes at least one first turning part that changes the circumference direction of the first pipe conduit,
wherein the first short circumference part extends around the storage chamber from the first near-end part side toward the first far-end part side,
wherein the first short circumference part extends along fewer wall surfaces than the first long circumference part,
wherein the first junction part includes an even number of the at least one first turning part such that the first short circumference part extends in the first circumference direction
wherein the second near-end part in the second pipe conduit is positioned lower than the first near-end part of the first pipe conduit,
wherein the second short circumference part is located closer to the second near-end part than the second long circumference part and the second junction part, the second long circumference part is located closer to the second far-end part than the second short circumference part and the second junction part, and the second junction part is located between the second short circumference part and the second long circumference part,
wherein the second short circumference part extends around the storage chamber from the second near-end part side toward the second far-end part side in the first circumference direction,
wherein the second short circumference part extends along fewer wall surfaces than the second long circumference part,
wherein the second junction part includes at least one second turning part that changes the circumference direction of the second pipe conduit,
wherein a number of the at least one second turning part is equal to the number of the at least one first turning part,
wherein the second long circumference part extends around the storage chamber from the second near-end part side toward the second far-end part side,
wherein the second long circumference part extends along more wall surfaces than the second short circumference part,
wherein the second junction part includes an even number of the at least one second turning part such that the second long circumference part extends in the first circumference direction
wherein the at least one first turning part includes a first turning part positioned N-th counted from the first near-end part side and the at least one second turning part includes a second turning part positioned N-th counted from the second near-end part side, and
wherein the first turning part positioned N-th counted from the first near-end part side and the second turning part positioned N-th counted from the second near-end side are disposed respectively on wall surfaces facing each other, where N is an even integer greater than or equal to 2.
