Abstract
The utility model discloses a tube plate type refrigerator evaporator which comprises heat exchange pipes and evaporating plates, wherein the heat exchange pipes are stuck on the evaporating plates in a snake shape. Curves arranged on two ends of adjacent heat exchange pipes arranged in parallel are in a '9' shape towards the same direction. A plurality of round fins are evenly arranged on the heat exchange pipes. The round fins arranged on adjacent heat exchange pipes are arranged in a stagger mode. Axial grooves are arranged in the inner walls of the heat exchange pipes. The tube plate type refrigerator evaporator is capable of obviously increasing effective length of an evaporating pipe, enlarging contact area between refrigerating fluid and the inner wall of the evaporating pipe, enlarging heat transfer area and obviously improving heat exchange efficiency.
Description
Technical field
The utility model relates to the evaporimeter of refrigerator in the refrigeration plant.
Background technology
Evaporimeter also is a kind of dividing wall type heat-exchange apparatus.The liquid refrigerant of low-temp low-pressure absorbs heat in the side gasification of heat conductive wall, thereby the medium of heat conductive wall opposite side is cooled.Existing evaporator of refrigerator as the evaporation and heat-exchange of cold-producing medium refrigeration, mainly contains blown plate type, tube-sheet type, and tube-sheet type wherein is by the coiled heat exchanger tube on heat exchanger plates and the heat exchanger plates face, with the single face adhesive tape heat exchanger tube is fixed on the heat exchanger plates to consist of.Because it is fixing that the adhesive tape employing is layouted, heat exchanger tube is round tube, and the heat exchanger plates warpage is large, planarization is poor, and can not be close between heat exchanger tube and the inner container of icebox, makes its contact area little, be that heat exchange area is little, so the heat exchange effect of heat exchanger plates is insufficient, so radiating effect is not very good yet.
Summary of the invention
The utility model provides a kind of effective length that can significantly increase evaporation tube for the deficiencies in the prior art, increases the contact area of cold-producing medium and evaporation tube inwall, and increasing heat radiation area significantly improves the tube-plate type evaporator for refrigerator of heat exchange efficiency.
The utility model is achieved through the following technical solutions technical goal.
Tube-plate type evaporator for refrigerator comprises heat exchanger tube, evaporation plate, and described heat exchanger tube is snakelike and is bonded on the evaporation plate, and its improvements are: the curve shape that is connected to two ends between the heat exchanger tube that described adjacent parallel is arranged is 9 fonts, and towards the same side; Evenly be provided with some Round fins on the described heat exchanger tube; The Round fin of adjacent heat exchange tubes is staggered; Described heat exchanger tube inwall is provided with axial groove.
The further technical scheme of the utility model is: described axial groove is helicla flute.
The another kind of further technical scheme of the utility model is: be provided with fin on the described fin.
The utility model compared with prior art has following good effect:
1. be provided with fin on the heat exchanger tube, be provided with fin on the fin, increased area of dissipation.
2. the curve shape that is connected to two ends between the heat exchanger tube that adjacent parallel is arranged is 9 fonts, and towards the same side, like this, the heat exchanger tube that is arranged in parallel can be arranged compactly, has increased the effective length of heat exchanger tube, improves heat exchange efficiency.
3. the heat exchanger tube inwall is made the tank circuit, has increased the contact area of cold-producing medium and heat exchanger tube inwall, thereby has increased heat exchange area.Moreover, because the tank circuit can form capillary effect, make the also corresponding increase of wetted area of its inner surface, also improved heat exchange area.The increase of heat exchange area can improve heat exchange property and heat transfer rate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure enlarged diagram of fin.
Fig. 3 is the I part enlarged diagram among Fig. 1.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
Tube-plate type evaporator for refrigerator shown in the accompanying drawing, comprise heat exchanger tube 1, evaporation plate 2, heat exchanger tube 1 is snakelike and is bonded on the evaporation plate 2, it is characterized in that: the curve shape that is connected to two ends between the heat exchanger tube 1 that adjacent parallel is arranged is 9 fonts, and towards the same side, increased like this effective length of heat exchanger tube; Evenly be provided with some Round fins 3 on the heat exchanger tube 1, the Round fin 3 of adjacent heat exchange tubes 1 is staggered; In the present embodiment, be provided with fin 4 on the fin 3.Round fin 3 is set on the heat exchanger tube 1, is provided with fin 4 on the fin 3, increased area of dissipation.
Heat exchanger tube 1 inwall is provided with axial groove 5, and in the present embodiment, axial groove 5 is helicla flute.Like this, increased the contact area of cold-producing medium and heat exchanger tube 1 inwall, thereby increased heat exchange area.
