Description

A kind of cold storage box and have the evaporimeter of this cold storage box

Technical field

The utility model belongs to the refrigerator technical field, relates to a kind of cold storage box of good effect of heat exchange, relates to a kind of evaporimeter with this cold storage box simultaneously.

Background technology

Along with popularizing of China's development of industry and agriculture and various household electrical appliance, domestic electric power situation growing tension, for responding relevant electric power policies such as country's " peak load shifting ", " tou power price ", a lot of refrigerator manufacturing firms have all released cold accumulation refrigerator, the cold accumulation refrigerator basic principle is: utilize the valley power ice making at night, cold is accumulated, and peak times of power consumption discharge satisfied temperature requirement with cold by day, realize the peak load shifting of power load thus.

The cold accumulation refrigerator that occurs is near the cold storage box that built-in agent for storage of coldness is set on the evaporimeter or the evaporimeter at present, and the surface of cold storage box is a regular planar, directly is fixed on the postnotum of refrigerating chamber in evaporimeter or the refrigerator; But when being fixed on cold storage box on the postnotum, cold storage box and evaporimeter be transmission of heat by contact effectively, even when cold storage box directly is fixed on the evaporimeter top, because the cold air that evaporimeter discharges is walked downwards, the condensation rate of agent for storage of coldness still can be affected, this is when being fixed on the evaporimeter below because of cold storage box, because the character of expanding with heat and contract with cold of agent for storage of coldness, can not fill when in cold storage box, adorning agent for storage of coldness, need stay the agent for storage of coldness needed space of expanding with heat and contract with cold, many layer of air heat-conducting mediums increase the condensation rate that a layer of air heat-conducting medium can influence agent for storage of coldness equally in the conduction process of agent for storage of coldness and evaporimeter in the cold storage box.

The utility model content

The purpose of this utility model is to provide a kind of cold storage box of good effect of heat exchange, and a kind of evaporimeter with this cold storage box is provided simultaneously.

For achieving the above object, cold storage box of the present utility model is by the following technical solutions: a kind of cold storage box, comprise the cold-storage box body that is used for the splendid attire agent for storage of coldness, the inside of cold-storage box body has agent for storage of coldness splendid attire chamber, and described cold-storage box body is provided with the one or more boss that communicates with the agent for storage of coldness splendid attire chamber of box body inside.

Have the contact-making surface that contacts with the evaporimeter corresponding matching on the described cold-storage box body, boss is arranged on this contact-making surface.

Described contact-making surface is the plane.

Described boss is arranged side by side the both sides at contact-making surface, and distribution or interval are in staggered distribution relatively.

For achieving the above object, evaporimeter of the present utility model is by the following technical solutions: a kind of evaporimeter, described evaporimeter comprises at least one evaporimeter layer, below each evaporimeter layer, cold storage box is set, cold storage box comprises the cold-storage box body that is used for the splendid attire agent for storage of coldness, the inside of cold-storage box body has agent for storage of coldness splendid attire chamber, and described cold-storage box body is provided with the one or more boss that communicates with the agent for storage of coldness splendid attire chamber of box body inside.

Have the contact-making surface that contacts with evaporimeter layer corresponding matching on the described cold-storage box body, boss is arranged on this contact-making surface.

Described contact-making surface is the plane.

Described evaporimeter layer is connected and composed by evaporation coil, and the bending part of each evaporation coil is stuck on the boss, and the height of described boss is no more than the height of evaporation coil.

Cold storage box of the present utility model and the evaporimeter with this cold storage box have shortened the cooling time of agent for storage of coldness, during use cold storage box is fixed on the below of evaporimeter layer, the boss that is provided with on the cold-storage box body snaps in gap and/or the bending part between the evaporation coil, and the steadiness of cold-storage box body is strengthened greatly; The height of boss is no more than the height of evaporimeter layer coil pipe, avoid being worn, the agent for storage of coldness needed space of expanding with heat and contract with cold is stayed in the boss, can make the agent for storage of coldness liquid level of perfusion be positioned at boss, so both guaranteed that agent for storage of coldness had enough spaces of expanding with heat and contract with cold, guarantee that also agent for storage of coldness can pass through the direct and evaporimeter layer heat exchange of outer wall of cold-storage box body, eliminate existing cold storage box and be positioned at the evaporimeter inner air layer that exists of when below, strengthen the effect of heat exchange greatly, shortened the cooling time of agent for storage of coldness; Cold storage box is arranged on the below of evaporimeter layer, is because the density of cold air is bigger, and refrigerator cold when operation is walked downwards, and the condensation rate of agent for storage of coldness was accelerated when cold storage box was positioned at the below of evaporimeter layer; The utility model makes agent for storage of coldness directly pass through the outer wall and the heat exchange of evaporimeter layer of cold-storage box body, strengthened the heat exchange effect of cold-storage box body and evaporimeter greatly, shortened the cooling time of agent for storage of coldness in the cold storage box, reduced the energy consumption of refrigerator, the boss that is provided with on the cold-storage box body snaps in gap and/or the bending part between the evaporation coil, increase the steadiness of cold storage box, had higher social value and economic worth.
