The present disclosure relates to a storehouse.
A storehouse may include a storage space for storing goods. Examples of the storehouse may include a refrigerator.
The refrigerator is an apparatus that cools objects to be cooled (e.g., food, drugs, and cosmetics) (hereinafter referred to as food for convenience), or stores food at low temperature so as to prevent spoilage and deterioration. The refrigerator includes a storage space in which food is stored, and a refrigeration cycle part that cools the storage space.
The refrigeration cycle part may include a compressor, a condenser, an expansion mechanism, and an evaporator, through which a refrigerant circulates.
A refrigerator according to the related art may include an outer case, and an inner case located inside the outer case and having an opened front side. Such a refrigerator may include a cold air discharge duct disposed inside the inner case to partition the inside of the inner case into a storage space and a heat exchange space. For example, the storage space may be defined in front of the cold air discharge duct, and the heat exchange space may be defined in the rear of the cold air discharge duct. An evaporator and an evaporating fan may be disposed in the heat exchange space.
The refrigerator may have a separate machine space defined outside the inner case. A compressor, a condenser, and a condensing fan may be disposed in the machine space. The compressor in the machine space may be connected to the evaporator in the heat exchange space through a refrigerant pipe.
The storage space may be provided with a withdrawable drawer. A plurality of the drawers may be provided in a vertical direction.
However, the refrigerator according to the related art as described above has the following problems.
First, the compressor in the machine space and the evaporator in the inner case are disposed in spaces separated from each other and are connected to each other by the refrigerant pipe. Therefore, when it is necessary to repair the refrigeration cycle part, it is inconvenient to take out food stored in the refrigerator so as to check and repair failure.
Second, since the evaporator has to be integrally formed inside the refrigerator body and the evaporator has to be fixed to the refrigerator body by welding or the like, there is an inconvenience in manufacturing the refrigerator. In addition, when the evaporator defrosts, heat exchange with the storage space increases the internal temperature of the refrigerator.
Third, since the heat exchange space is disposed in the rear of the storage space, the width of the rear wall of the refrigerator body in the front-and-rear direction increases as much as the size of the heat exchange space. Therefore, the volume of the storage space is reduced as much.
In order to solve these problems, a refrigerator including a cooling module that integrally configures a heat absorbing portion and a heat dissipating portion has been proposed.

At least a part of the second passage may be provided to be exposed to the second storage space.
Fourth, the fluid generator may be disposed in at least one of the inside of the first passage and the inside of the second passage. In this case, since the distance between the first heat exchanger and the fluid generator may be separated, there is an advantage that can reduce a dead zone that may occur in the flow passage of the fluid. The passage on which the fluid generator is disposed may include a portion protruding toward the first storage space. Therefore, the volume of the first storage space may be increased. The fluid generator may be disposed inside the protruding portion.

For example, the fluid generator may include a fan and a fan housing.

The width W2 of the second case part 110b in the front and rear direction may be larger than the width W1 of the first case part 110a in the front and rear direction so that the relatively bulky compressor 141, second heat exchanger 143, and second heat exchanger fan 145 can be accommodated inside the second case part 110b.
In response to the increased width of the second case part 110b in the front and rear direction, a case protrusion 111 may be provided at the end portion of the second case part 10b, that is, at the boundary between the first and second case parts 110a and 110b.
For example, the case protrusion 111 may protrude forward from the lower end portion of the first case part 110a.
A tray 160 may be placed in the accommodation space of the second case part 110b. Since the tray 160 is configured to have a large volume for storing fluid, the width in the front and rear direction can be increased by being placed in the second case part 110b rather than the first case part 110a.
By configuring the first case part 110a to have a relatively small width in the front and rear direction, the width of the first storage compartment 15a in the front and rear direction formed in front of the first case part 110a can be increased.
