Description

An ice machine with improved heat dissipation air duct

technical field

The utility model relates to a heat dissipation air duct system for an ice maker, in particular to a heat dissipation air duct system which utilizes a compressor for refrigeration, utilizes a condenser for heat dissipation, and utilizes a fan motor to strengthen air flow.

Background technique

At present, in order to ensure good heat dissipation of ice machine products on the market, fans and motors are generally installed near the condenser to enhance heat dissipation. The common methods are as follows: 1. Straight-through air duct cooling system; 2. , Isolated air duct cooling system.

Straight-through cooling air duct system, as the name suggests, is a cooling air duct system in which air enters from one end and exits from the other end. It is mainly composed of inlet grille, outlet grille, condenser, fan motor, U-shaped chamber and other components. The ice machine forms a U-shaped chamber at the bottom through the left and right side plates and the bottom plate of the shell, forming the basic outline of an air duct. At the front end of the U-shaped cavity, an air inlet grill is installed, and the air inlet grill is composed of a The metal plate is formed by folding around the edges, and several ventilation holes are processed on the plane, and the fresh air enters the U-shaped chamber from the air intake grill; On the condenser, the condenser is hung on the bottom plate by screws. The condenser generally adopts a copper tube aluminum fin structure and is surrounded by thin steel plates to ensure that the air can only enter from one end and come out from the other end; The compressor has an outlet grille at the end, and the structure of the outlet grille is similar to that of the inlet grille. Fresh cold air is sucked in from the intake grille by the fan motor, blown to the condenser, and then blown to the compressor, so that the heat generated by the condenser and compressor is exhausted from the outlet grille to form a complete cooling air road system.

The main structure of the isolated air duct cooling system is similar to that of the straight-through cooling system. The difference is that there is an isolation plate to isolate the U-shaped chamber in parallel into left and right half chambers. The fan motor and condenser are installed in the In the left half chamber (or right half chamber), the compressor is placed at the end, the outlet grille is canceled (that is, it is closed), and the fresh cold air is drawn by the fan motor from the left (or right) of the inlet grille Intake, blow to the condenser, compressor, the heat of the condenser and compressor products flows through the right half cavity (or left half cavity), and is discharged from the other side of the intake grille.

The advantages of adopting the straight-through heat dissipation air duct system are: simple structure and strong heat dissipation capacity; its disadvantage is that the installation position of the ice machine using this heat dissipation system has limitations and cannot be placed in the Inside the cabinet; the advantage of using the isolated air duct cooling system is that the air inlet and outlet are respectively realized by half of the air inlet grille, the installation limitations of the ice machine are improved, and it can be easily installed in a closed space such as a kitchen ; Disadvantages are: because the air inlet and outlet pass through the same grille, there is a mixing phenomenon of hot and cold air, which affects the heat dissipation effect, but when used in tropical areas (T-type climate), the ice-making capacity will be reduced; in addition, due to Isolate the U-shaped chamber into two half chambers on the left and right, and the installation space of the condenser and fan motor is limited. In order to ensure sufficient heat dissipation, the width of the ice making cannot be less than 400mm, which limits the application of this system on smaller ice machines. use.
