Description

Technical Field

[0001] The invention relates to the technical field of refrigeration, and in particular to a self-portable air curtain cabinet capable of enhancing condensation effect. Background Art

[0002] At present, the self-contained air curtain cabinet can prevent the condenser from having limited space, and cannot achieve the best condensation effect. It is subject to great limitations in design. Moreover, in actual application, users cannot leave enough heat dissipation space for the air curtain cabinet. Therefore, a single condenser is limited by space and it is difficult to achieve the desired condensation effect. The condensation effect of the entire air curtain cabinet will be very poor, which will lead to weak heating capacity in the cabinet and even high temperature alarm. Summary of the invention

[0003] In view of the above problems, the present invention provides a self-portable air curtain cabinet which can enhance the condensation effect.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A self-contained air curtain cabinet capable of enhancing condensation effect comprises a cabinet, a compressor, a condenser, a filter drier, a throttling element and an evaporator. The compressor, the filter drier, the first condenser, the throttling element and the evaporator are sequentially connected to form a refrigeration cycle. A second condenser is provided, which is located between the compressor and the filter drier in the refrigeration cycle and is connected to the compressor and the filter drier respectively. The compressor and the first condenser are respectively located in the cavity at the bottom of the cabinet, the first condenser is located at the front side of the bottom cavity, and a fan is also provided between the compressor and the first condenser. The evaporator is fixed to the inner wall at the rear side of the cabinet, and the second condenser is located below the evaporator. A water baffle is also provided, which is located between the evaporator and the second condenser, the upper end of the water baffle is fixed to the lower part of the front side of the evaporator, and the lower end is a free end and has a gap with the inner wall at the rear side of the cabinet. The lower end of the water baffle is located above the second condenser, and the condensed water of the evaporator can be guided to water-cool the second condenser.

[0006] Furthermore, the water baffle is bent, and the lower end is inclined toward the second condenser.

[0007] Furthermore, the second condenser is a small condenser.

[0008] The beneficial effect of the present invention is that by adding a small condenser below the evaporator and connecting the two condensers in series, the problem of poor condensation effect caused by small heat dissipation space can be avoided. The condensed water from the evaporator is guided by the water baffle to cool the second condenser, which has a simple structure and can save energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] A self-contained air curtain cabinet that can enhance the condensation effect, combined with Figure 1 and Figure 2 As shown, it includes a cabinet 7, a compressor 1, a condenser, a filter drier 3, a throttling element 4 and an evaporator 6, and the condenser includes a first condenser 2 and a second condenser 5. The compressor 1, the second condenser 5, the filter drier 3, the first condenser 2, the throttling element 4 and the evaporator 6 are connected in sequence to form a refrigeration cycle. The compressor 1 and the first condenser 2 are respectively located in the cavity at the bottom of the cabinet 7, the first condenser 2 is located at the front side of the bottom cavity, and a fan is arranged behind the first condenser 2. The second condenser 5 is a small condenser, which is located below the evaporator 6 and fixed on the rear side wall of the cabinet 7. The evaporator 6 is fixed on the rear inner wall of the cabinet 7, and the water baffle is located between the evaporator 6 and the second condenser 5. The water baffle is bent, the upper end of the water baffle is fixed to the lower front side of the evaporator 6, and the lower end is a free end and has a certain gap with the rear inner wall of the cabinet 7. The lower end of the water baffle is inclined toward the second condenser 5, and the water baffle can guide the condensed water of the evaporator 6 to water-cool the second condenser 5.

[0013] The design principle of the present invention is as follows: first, the high-temperature and high-pressure refrigerant vapor discharged from the compressor 1 enters the second condenser 5, and at the same time, the condensed water of the evaporator 6 is guided by the water baffle to perform the first step of water cooling on the second condenser 5. When the refrigerant enters the first condenser 2 from the second condenser 5, the second step of air cooling is performed by the fan located between the compressor 1 and the first condenser 2 and facing the first condenser 2. The refrigerant in the second condenser 5 and the first condenser 2 is cooled respectively by the first step of water cooling and the second step of air cooling. Compared with the common single condenser in the refrigeration cycle, the present invention can greatly improve the condensation effect.

[0014] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
