Clean and small-size vertical cabinet type indoor unit

Abstract

The invention relates to a clean and small-size vertical cabinet type indoor unit which comprises a machine box, exhaust fan blades, an evaporator, a draught fan, a heat exchange pipe, a plurality of heat exchange fins and an installing and welding panel. Each heat exchange fin comprises a fin body, an upper bent plate and a lower bent plate, wherein the upper bent plate and the lower bent plate are formed at the top and the bottom of the fin body. A flow guide cavity is formed between every two adjacent fin bodies and between the upper bent plate and the lower bent plate, and the multiple flow guide cavities are arranged side by side in a grid shape and cover an air outlet formed by the exhaust fan blades. The installing and welding panel comprises a panel main body and a wire arrangement structure. On one hand, airflow at the air outlet can be prevented from flowing disorderly, the air outlet efficiency can be improved, meanwhile, the heat exchange fins additionally arranged at the air outlet can further conduct heat exchange on air obtained after heat exchange, then the refrigeration effect is improved, in addition, the vertical cabinet type layout is adopted, the evaporator is obliquely arranged, the size is reduced, and the occupied space is small. On the other hand, disorder and neatness of wires are avoided, and accurate replacement of the wires and switches is facilitated.

Description

technical field [0001] The invention belongs to the field of air coolers, and in particular relates to a tidy and small vertical cabinet type indoor unit. Background technique [0002] Air coolers are divided into refrigeration industrial air coolers and household air coolers. Industrial air coolers are generally used in cold storage and cold chain logistics refrigeration environments. Household air coolers are also called water-cooled air conditioners. All in one evaporative cooling ventilator unit. [0003] Among the industrial air coolers in the refrigeration industry, the most common is the split vertical cabinet air cooler, which is mainly used for cooling the cab, operating room and electrical room (room) of mobile equipment when the ambient temperature is lower than 75°C, which can keep the indoor temperature low. Between 22-35°C. [0004] Specifically, the air cooler includes an indoor unit and an outdoor unit, in which the air circulation formed by the evaporator ...

AI Technical Summary

Problems solved by technology

[0007] 1. For the convenience of processing, the upper and lower ends of the grille are open. In this way, when the gas passes through the airflow channel formed by the grille, the gas will escape up and down, forming a circulation in the air outlet cavity, which affects the air outlet. Efficiency, resulting in poor cooling effect;

[0008] 2. The general clean and small vertical cabinet indoor unit is relatively large and will inevitably take up a lot of space;

[0009] 3. All the operating switches and buttons of the indoor unit are set on the panel of the indoor unit, and the switches and buttons need to be connected with wires or cables, which will cause many internal wiring of the indoor unit, which is very confusing. , When the button is replaced, it is often difficult to distinguish which switch and the wire corresponding to the button, causing inconvenience
