Problems solved by technology

However, this direct cooling refrigerator has the following disadvantages: if the overall height H of the inner box 5 is used as a benchmark, the evaporator tube 12 is wound on the interval from 5H / 6 to H / 3, that is to say , when looking at the storage space 6 as a whole, the evaporator tube 12 is wound below the middle of the storage space 6
When refrigerating, the air that exchanges heat with the medium passing through the evaporator tube 12 flows to the lower part of the storage space 6 through natural convection. overcooled

Embodiment Construction

[0011] Such as figure 2 As shown, the inner box body 30 is disposed inside the main body of the direct cooling refrigerator, and the inner box body 30 has a storage space 32 inside. The inside of the storage space 32 is provided with a storage room again, the top is a storage room 34, and the bottom is a storage room 34', and storage items can be placed in the inside of the storage room 34 and 34' for storage. The upper storage compartment 34 is placed on top of the lower storage compartment 34'. In order to set the temperature inside the storage space 32 , a heater 40 and an evaporator pipe 50 are wound around the outside of the inner box 30 . The function of the heater 40 is to use the heat generated by it to ripen the storage items stored in the storage space 32; the function of the evaporator tube 50 is to keep the storage space 32 at a relatively low temperature through the flow of the medium of the refrigerating cycle inside it. Down. When the heater 40 is wound arou...

Abstract

An evaporator and heater structure for directly freezing refrigerator is characterized by that its internal case has an internal storage space, the evaporator's tube is wound around the external surface of the upper half of said internal case, and the heater is wound around the external surface of its lower half. It can prevent excessive cold air after heat exchange from being transferred downward, resulting in uniform temp in storage space.

Description

technical field [0001] The invention relates to a heater and an evaporator arrangement structure of a direct-cooling refrigerator, in particular to a heater and an evaporator arrangement structure of a direct-cooling refrigerator capable of controlling the internal temperature of a storage space. Background technique [0002] figure 1 A side view of the structure of the evaporator and the heater of the direct cooling refrigerator in the prior art. Such as figure 1 As shown, the lower part of the main body 1 of the direct cooling refrigerator is provided with a mechanical room 3, and various components required for starting the refrigerator are provided inside the mechanical room 3. Inside the main body 1 is provided a storage space 6 that can be divided by the inner box body 5 , and the storage space 6 is located above the machine room 3 . The refrigerator door 7 is arranged on the upper end of the main body 1, and it can selectively open and close the storage space 6, so...
