Abstract

A refrigeration device includes an indoor unit and an outdoor unit. The indoor unit is used for heat exchange with air inside an equipment room. To adapt to different cabinets, one or more ventilation ducts of the indoor unit include a plurality of channels, and a baffle assembly is disposed in the indoor unit. An air flow direction in the ventilation duct is changed using the baffle assembly, and the baffle assembly is adjusted to block different positions to apply the refrigeration device to different types of cabinets.

First claim

What is claimed is:

1. A refrigeration device comprising:
an indoor component comprising:
a first ventilation duct and a second ventilation duct that are arranged along a same direction in relation to a top of a cabinet;
a first ventilation opening comprising a first side and a second side, wherein the first ventilation duct and the second ventilation duct are configured to communicate with each other through the first ventilation opening;
a first evaporation assembly disposed in the first ventilation duct and further disposed on the first side of the first ventilation opening;
a second evaporation assembly disposed in the second ventilation duct and further disposed on the second side of the first ventilation opening;
a baffle assembly configured to adjust air intake directions of the first ventilation duct and the second ventilation duct,
wherein, in a first state, the baffle assembly is configured to:
separate the first ventilation duct from the second ventilation duct; and
adjust the first ventilation duct and the second ventilation duct to supply air in a same direction, and

wherein, in a second state, the baffle assembly is further configured to adjust the first ventilation duct and the second ventilation duct to separately let in air from the top of the cabinet and to supply air in opposite directions; and

an outdoor component coupled to the indoor component and comprising a condenser configured to separately perform heat exchange with each of the first evaporation assembly and the second evaporation assembly.

2. The refrigeration device of claim 1 , wherein the indoor component further comprises a third ventilation duct configured to penetrate the first ventilation duct and the second ventilation duct and connect the first ventilation duct to the second ventilation duct, wherein the first ventilation opening is located in the third ventilation duct, wherein an air intake vent of the third ventilation duct is proximate to the second ventilation duct, wherein the first ventilation duct is divided into a first subchannel and a second subchannel by the third ventilation duct, wherein the second ventilation duct is divided into a third subchannel and a fourth subchannel by the third ventilation duct and, wherein the first subchannel is located on a third side of the third ventilation duct, wherein the fourth subchannel is located on a fourth side of the third ventilation duct, wherein the first evaporation assembly is located in the first subchannel, wherein the second evaporation assembly is located in the second subchannel, wherein, in the first state, the baffle assembly is further configured to:
couple the first subchannel to the second subchannel;
couple the second subchannel to the fourth subchannel; and
clock the air intake vent, and
wherein, in the second state, the baffle assembly is further configured to;
couple each of the first subchannel and the fourth subchannel to the third ventilation duct to enable the first subchannel and the fourth subchannel to let in air through the third ventilation duct; and
separate each of the second subchannel and the third subchannel from the third ventilation duct.

3. The refrigeration device of claim 2 , wherein the indoor component further comprises a housing with two ends having openings, wherein a partition board is disposed in the housing, and configured to divide a cavity in the housing into the first ventilation duct and the second ventilation duct, wherein a second ventilation opening is disposed on a first side wall of the housing facing the cabinet, wherein the first ventilation opening is disposed on the partition board, wherein the second ventilation opening and the first ventilation opening communicate with each other and are located in the third ventilation duct, and wherein the second ventilation opening is the air intake vent.

4. The refrigeration device of claim 3 , wherein the baffle assembly comprises;
a first baffle coupled to the partition board in a first rotatable manner;
a second baffle coupled to the partition board in a second rotatable manner; and
a third baffle coupled to the first side wall and configured to block the second ventilation opening,
wherein, in the first state, the first baffle is configured to rotate to a first position, the second baffle is configured to rotate to a second position, the first baffle and the second baffle are configured to block the first ventilation opening, the first subchannel is coupled to the second subchannel, the third subchannel is coupled to the fourth subchannel, and the third baffle is configured to block the second ventilation opening, and
wherein, in the second state, the first baffle is configured to rotate to a third position and separate the third subchannel from the third ventilation duct, the second baffle is configured to a fourth position and separate the second subchannel from the third ventilation duct, and the third baffle is configured unblock the second ventilation opening to open the second ventilation opening.

5. The refrigeration device of claim 4 , wherein the baffle assembly further comprises:
a first driving mechanism configured to drive the first baffle to rotate and be locked in the first position or the third position; and
a second driving mechanism configured to drive the second baffle to rotate and be locked in the second position or the fourth position.

6. The refrigeration device of claim 5 , wherein the third baffle is coupled to the first side wall in a slidable manner, wherein, in the first state, the third baffle is configured to slide to a fifth position and block the second ventilation opening, and wherein, in the second state, the third baffle is further configured to slide to a sixth position and open the second ventilation opening.

7. The refrigeration device of claim 5 , wherein the third baffle is coupled to the first side wall in a rotatable manner, wherein, in the first state, the third baffle is configured to rotate to a seventh position and block the second ventilation opening, and wherein, in the second state, the third baffle is further configured to rotate to an eighth position and open the second ventilation opening.

8. The refrigeration device of claim 4 , wherein the third baffle is coupled to the first side wall in a slidable manner, wherein, in the first state, the third baffle is configured to slide to a fifth position and block the second ventilation opening, and wherein, in the second state, the third baffle is further configured to slide to a sixth position and open the second ventilation opening.

9. The refrigeration device of claim 8 , wherein the baffle assembly further comprises a third driving mechanism configured to drive the third baffle to slide and be locked in the fifth position or the sixth position.

10.
