Abstract

The utility model discloses an evaporator of a direct-cooling refrigerating device. The refrigerating device is provided with at least one refrigerating chamber defined by outer walls, wherein the refrigerating chamber is cooled by the evaporator connected in a closed refrigerating circuit. The evaporator comprises two evaporating aluminum tubes and aluminum foil layers pasted onto the outer tube walls of the evaporating aluminum tubes. The two evaporating aluminum tubes are wound on the outer wall of the refrigerating chamber side by side, a plurality of C-shaped tube clamps are arranged between the two evaporating aluminum tubes wound side by side, and the plurality of C-shaped tube clamps are distributed along the winding direction of the evaporating aluminum tubes. Each C-shaped tube clamp is provided with an inner cavity, and partial tube sections of the two evaporating aluminum tubes wound side by side are clamped into the inner cavities of the C-shaped tube clamps at the same time. The evaporator of the direct-cooling refrigerating device has the advantages that straightness of the evaporating aluminum tubes is guaranteed, the two aluminum tubes are closely attached to the outer wall of the refrigerating chamber at the same time, and the usage amount of aluminum tape is reduced; and in addition, for a low-temperature type freezer, due to the fact that the cooling capacity demand of the low-temperature type freezer is high and an evaporating tube wound in a single circle can not meet the cooling capacity demand, the method that the double tubes are wound side by side is needed for achieving the purposes of enlarging refrigerating areas and increasing refrigerating capacities.

Description

The evaporimeter of direct-cooling type refrigeration plant

Technical field

The utility model relates to a kind of evaporimeter of direct-cooling type refrigeration plant.

Background technology

Notification number is that the evaporimeter in the Direct cold refrigerator of band drawer of CN2540609Y is evaporimeter the most common in the conventional art, this direct-cooling type refrigeration plant adopts the evaporimeter of individual pen aluminum pipe coiling, the restriction that the directly cooling evaporator heat transfer efficiency is lower, the length of the evaporation tube of individual layer coiling is limited by box sizes, it is overstocked to cause pipeline to arrange after evaporation tube lengthens, and influences the moulding of casing integral foam.

The utility model content

The purpose of this utility model provides a kind of evaporimeter of easy to make, direct-cooling type refrigeration plant that refrigerating efficiency is high.

For achieving the above object, the technical solution adopted in the utility model is: a kind of evaporimeter of direct-cooling type refrigeration plant, this direct-cooling type refrigeration plant has the refrigerating chamber that at least one is surrounded by outer wall, described refrigerating chamber is by an evaporator cools that is connected in the closed refrigerating circuit, described evaporimeter comprises two evaporation aluminum pipes, stick on the aluminium foil layer on the outer tube wall of described evaporation aluminum pipe, two described evaporation aluminum pipes are wrapped on the outer wall of described refrigerating chamber side by side, be provided with a plurality of C shape pipe clamps between described two evaporation aluminum pipes of Chan Raoing side by side, a plurality of described C shape pipe clamps distribute along the winding direction of described evaporation aluminum pipe, described C shape pipe clamp has an inner chamber, and the part pipeline section of described two evaporation aluminum pipes of Chan Raoing is clamped in the inner chamber of described C shape pipe clamp simultaneously side by side.

In the preferred version, the outer wall of described refrigerating chamber comprises perisporium and diapire, and described evaporation aluminum pipe is wrapped on the perisporium.

In the preferred version, described C shape pipe clamp is plastic clip or metal clip.

Because technique scheme is used, the utility model compared with prior art has following advantage: the evaporimeter of direct-cooling type refrigeration plant of the present utility model adopts the double joint evaporation tube, and two evaporation aluminum pipes that will twine are side by side tied up fixing with C shape pipe clamp, one, guaranteed the grazing of evaporation aluminum pipe, guaranteed that 2 aluminum pipes are close to the refrigerating chamber outer wall simultaneously, save the aluminum foil and adhesive tape use amount, guaranteed the uniformity of equipment complete machine performance; Two, to some low form household freezers, because cold requires height, the evaporation tube of individual pen coiling does not reach the cold requirement, just need two-tube coiling side by side reach the purpose that increases refrigeration area, increases refrigerating capacity.

Description of drawings

Accompanying drawing 1 is the structural representation of the evaporator section of direct-cooling type refrigeration plant of the present utility model;

Accompanying drawing 2 is C shape pipe clamp longitudinal cross-section view;

In the above accompanying drawing: 1, refrigerating chamber; 11, perisporium; 2, evaporimeter; 21, evaporation aluminum pipe; 22, C shape pipe clamp; 23, inner chamber.

The specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is further described:

Accompanying drawing 1 is depicted as the part-structure schematic diagram of direct-cooling type refrigeration plant, this direct-cooling type refrigeration plant has a refrigerating chamber 1 that is surrounded by outer wall, refrigerating chamber 1 is by evaporimeter 2 coolings that are connected in the closed refrigerating circuit (not shown), wherein the outer wall of refrigerating chamber 1 includes perisporium 11 and diapire, evaporimeter 2 comprises and is close to two evaporation aluminum pipes 21 that refrigerating chamber perisporium 11 twines side by side, stick on the aluminium foil layer (not shown) on the outer tube wall that evaporates aluminum pipe 21, be provided with a plurality of C shape pipe clamps 22 along winding direction between adjacent two evaporation aluminum pipes 21, a plurality of C shape pipe clamps 22 evenly distribute along the winding direction of evaporation aluminum pipe 21, and the part pipeline section of adjacent two evaporation aluminum pipes 21 is clamped in the inboard of C shape pipe clamp 22 simultaneously.

As shown in Figure 2, the inboard of C shape pipe clamp 22 forms an inner chamber 23, and the interior cross-sectional area of inner chamber 23 is designed to lucky banding two adjacent rings evaporation aluminum pipe 21, and adjacent like this two evaporation aluminum pipes 21 just in time can be contained in its inner chamber 23 and can not rock.The material of C shape pipe clamp 22 can select for use hard PVC or hard metal to make.C shape pipe clamp 22 can be before the operation that evaporation aluminum pipe 21 and aluminum foil and adhesive tape are pasted, adjacent two evaporation aluminum pipes, 21 usefulness C shape pipe clamps 22 are tied up re-use aluminum foil and adhesive tape after fixing the evaporation aluminum pipe 21 that has fixed is pasted, aluminium foil and the sticking efficiency between two fixing evaporation aluminum pipes 21 and sticking Quality improve like this, save the use amount of aluminum foil and adhesive tape, and improved the uniformity of refrigeration plant complete machine refrigeration performance.
