Display cabinet with back condenser

Abstract

The invention relates to the technical field of display cabinets, and provides a display cabinet with a back condenser. The display cabinet with the back condenser effectively shrinks the structural size of a compressor bin, has wider applicability and meanwhile improves heat dissipation efficiency. The display cabinet comprises a cabinet body, the compressor bin, the condenser and a cooling fan, the cabinet body comprises a back portion and a cover plate, the condenser and the cooling fan are both arranged on the back portion and covered with the cover plate, the cover plate is provided with a first air inlet and a first air outlet, the cooling fan is provided with a second air inlet and a second air outlet, the second air inlet is formed at the first air inlet, and the condenser is arranged at the second air outlet. Air enters the second air inlet through the first air inlet, flows to the condenser through the second air outlet, and finally flows out through the first air outlet, and cooling airflow is formed. The condenser and the cooling fan are arranged on the back portion of the cabinet body, and therefore the structural size of the compressor bin is shrunk, and the heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of display cabinet manufacturing, and more specifically, to a display cabinet with a back condenser. Background technique [0002] In the prior art, there are generally two installation methods for the condenser of a showcase with refrigeration and freezing functions: one is to install the condenser in the compressor compartment of the showcase, and use a cooling fan to force heat dissipation; The condenser is hung on the rear cover of the showcase to let it dissipate heat naturally in the air. [0003] The above two installation methods of condensers have considerable disadvantages: the first installation method requires a large enough space in the compressor compartment to install the condenser and cooling fan, which is only suitable for larger display cabinets. This installation method cannot be applied to relatively small showcases, which has great application limitations. Due to the small size of the ...

Problems solved by technology

[0003] The above two installation methods of condensers have considerable disadvantages: the first installation method requires a large enough space in the compressor compartment to install the condenser and cooling fan, which is only suitable for larger display cabinets. This installation method cannot be applied to relatively small display cabinets, which has great application limitations

Due to the small size of the desktop display cabinet, if the condenser is installed in the compressor compartment according to the assembly method of the conventional vertical display cabinet, and then the fan is used to force the heat dissipation, the space of the compressor compartment must be limited due to structural constraints. If the condenser is forced to be placed in the compressor compartment at the bottom of the cabinet, it will increase a lot of cost

[0004] The second installation method is to dissipate the heat of the condenser naturally, so the heat dissipation efficiency is low

For desktop refrigerated display cabinets, due to the large temperature difference between the inside and outside of the cabinet, the heat load of the system is very large. If natural heat dissipation is used, the area of ​​the condenser is not enough due to the small size of the desktop display cabinets.

According to the test results, due to insufficient heat dissipation, the exhaust temperature of the refrigeration system will exceed 110°C, and the temperature of the condenser will reach 65~70°C, which greatly affects the refrigeration efficiency and reliability of the refrigeration system

In addition, the condenser is easy to touch obstacles such as walls, which not only reduces the heat dissipation efficiency, but also easily damages the condenser. Moreover, the temperature of the back is too high, and the user can directly touch it, which has the risk of scalding the user and causing accidents

[0005] Especially for refrigerated showcases, which are different from ordinary refrigerated showcases, due to the low temperature and the glass door, resulting in a very large heat load, the traditional way of natural cooling of the back condenser cannot meet the needs of the system

Moreover, due to the limitation of the structural size, the compressor compartment cannot provide space for placing devices such as condensers and cooling fans.
