Description

A kind of freezer efficient air cooler

Technical field

The utility model belongs to freezer refrigerating equipment technical field, relates generally to a kind of efficient air cooler of freezer.

Background technique

At work, air is under fan action by completing heat between heat exchanger and heat exchange fin for the air-cooler of freezer Amount exchanges, and in exchange process, the vapor in air condenses into droplet on heat exchange fin, and droplet drops onto cold wind motor spindle peace It is discharged after on the drip tray of dress by drainpipe.But since the temperature of freezer is lower, the water electrode on drip tray easily freezes, when serious The water outlet on drip tray can be blocked, causes draining limited.In the prior art to solve the problems, such as drip tray impeded drainage, generally It is to install heating wire additional on the surface of drip tray, melts the icing of drip tray by the heat of heating wire generation.But using this After mode, since heating wire is exposed in water receiving panel surface, thus most of heat that heating wire generates can be through being lost to peripheral ring In border, freezer causes energy consumption to improve because temperature increases, and wastes electric power resource.

Utility model content

The purpose of this utility model is: providing the freezer efficient air cooler that a kind of structure is simple, low energy consumption.

The technical solution of the utility model is: a kind of freezer efficient air cooler, including shell and installs on the shell Blower and heat exchange coil are fixed with drip tray in the bottom of shell, the heat exchange coil along air-flow direction at least provided with Inside and outside two layers, it is laid with heat exchange fin respectively on inside and outside two layers of heat exchange coil, the spacing between the heat exchange fin of outer layer Greater than the heat exchange fin of internal layer；The drip tray is hollow jacket structure, and thermal insulation material is filled in the hollow jacket, Electric heating wire is embedded in thermal insulation material, the electric heating wire is close to the upper surface of drip tray.

The drip tray is in rectangular configuration, is integrally formed in the surrounding of drip tray and bends upward water blocking edge, and wherein one The water blocking edge of side, which is above coated with, protrudes into the conducting wire that the hollow jacket is connect with electric heating wire.

Spacing between the outer layer heat exchange fin is 2 times of internal layer heat exchange fin spacing.

The freezer of the utility model is easier the spy of frosting with efficient air cooler according to the outer layer fin of conventional heat transfer coil pipe Point, the spacing that will be located at the heat exchange fin of outer layer increase, on the one hand can effectively extend the time of heat exchanger surface frosting, subtract Few influence of the fin surface frosting to equipment, on the other hand can reduce the influence that air is flowed in the frosting of outer layer fin surface, To achieve the purpose that reduce equipment energy consumption, the drip tray of cold wind motor spindle installation is using hollow jacket structure and in hollow jacket Thermal insulation material in bury dress electric heating wire, so that drip tray is formed the heating device that matches with heat exchange fin, completion heat exchange fin The change ice work of drip tray, has the characteristics that structure is simple, easy to install and use, can effectively reduce heat when defrost It scatters and disappears, to reduce the energy consumption of equipment, solves prior art defrost energy consumption height, library temperature Wen Shenggao, drip tray and discharge outlet The problem of easily freezing.

Specific embodiment

The specific embodiment of the freezer efficient air cooler of the utility model is as shown in Figure 1 comprising shell 1 and is mounted on Blower 2 and heat exchange coil 2 on shell 1 are fixed with drip tray 4 in the bottom of shell 1, wherein heat exchange coil 2 as shown in Fig. 2, Its along air-flow direction at least provided with inside and outside two layers 31,32, it is spaced and parallel on each layer heat exchange coil 3 to be laid with several change Hot fin, wherein spacing between the heat exchange fin 31 of outer layer is greater than the heat exchange fin 32 of internal layer, should in the present embodiment Spacing between outer layer heat exchange fin 31 is 2 times of spacing between internal layer heat exchange fin 32.The structure of drip tray 4 as shown in figure 3, Generally hollow jacket structure is embedded with electricity in thermal insulation material 42 and adds filled with thermal insulation material 42 in the hollow jacket for it Heated filament 43, the electric heating wire 43 is close to the upper surface of drip tray 4.In the present embodiment, which is adaptation 1 bottom shape of shell The rectangular configuration of shape is integrally formed in the surrounding of drip tray 4 and bends upward water blocking along 44, to form one in drip tray 4 A water receiving tank 41, for convenience of the connection of electric heating wire 43, the water blocking in wherein side is coated with along 44 protrudes into hollow jacket In and the conducting wire 45 that is connect with electric heating wire 43.The freezer efficient air cooler of the utility model is according to the outer of conventional heat transfer coil pipe The characteristics of layer fin is easier frosting, the spacing that will be located at the heat exchange fin of outer layer increase, on the one hand can effectively extend and change The time of hot device surface frosting reduces influence of the fin surface frosting to equipment, on the other hand can reduce outer layer fin surface The influence that air is flowed in frosting, to achieve the purpose that reduce equipment energy consumption, in the drip tray use that cold wind motor spindle is installed Dress electric heating wire is buried in empty jacket structured and thermal insulation material in hollow jacket, not only the surface of drip tray can be enable to begin It is maintained above freezing eventually, condensed water is avoided to freeze in water receiving panel surface, thus caused by effective solution drip tray freezes The problem of impeded drainage, while the heat that electric heating wire generates can effectively reduce electric heating wire work under thermal insulation material effect Thermal losses when making solves the problems, such as of the existing technology.
