Abstract
The invention discloses a refrigeration evaporator of a refrigerator. The refrigeration evaporator comprises an evaporating pipe, wherein the evaporating pipe is bent in an S shape and comprises bending parts and parallel parts, and fins are respectively arranged between adjacent parallel parts of the evaporating pipe; each fin comprises a metal plate and a pair of involution parts which are integrally formed together with the metal plate; and the involution parts are symmetrically arranged on two opposite sides of the metal plate, cavities which are used for storing the parallel parts of the evaporating pipe are formed in a way that respective involution parts of two adjacent fins are involuted, and the inner walls of the cavities are seamlessly abutted with the outer walls of the parallel parts. The problem of refrigerant leakage is solved, and the effect of high heat exchange efficiency is achieved.
Description
Technical field
The present invention relates to refrigeration technology field, a kind of specifically refrigerator freezing vaporizer.
Background technology
Vaporizer is the requisite critical piece in the refrigeration system of refrigerating plant, and refrigerator freezing vaporizer is often
Using to tube-in-sheet evaporator and propel the price of formula vaporizer, but each have their own shortcoming of both vaporizers.
For tube-in-sheet evaporator, it is all using binding agent, refrigeration piping to be pasted on a metal plate, to reach mostly
To the effect increasing heat exchange area.But the coefficient of heat transfer problem due to binding agent itself, can make refrigeration piping and metallic plate it
Between thermal resistance occurs, make heat exchange efficiency reduce, affect refrigeration.If additionally, binding agent sticking effect is bad, refrigeration piping bounce-back
Power is excessive or metallic plate deformation, tube sheet all can be caused to separate, make heat transfer uneven, causes to freeze bad.
And although its heat exchange efficiency is higher for propelling the price of formula vaporizer, but due to propel the price of formula vaporizer be by
The mutual extrusion molding of two pieces of metallic plates, so the not tight gap of extruding can occur between metallic plate unavoidably, thus can make
Become leakage of refrigerant, do not reach refrigeration.
Content of the invention
The invention is intended to offer is a kind of can solve the problems, such as leakage of refrigerant and the higher refrigerator freezing evaporation of heat exchange efficiency
Device.
The technical solution used in the present invention is as follows：Refrigerator freezing vaporizer, including evaporation tube, described evaporation tube is in S shape
Bending, including bending section and parallel portion, evaporation tube is equipped with fin between adjacent parallel portion；Described fin includes metal
Plate and a pair of pairing portion integrally formed with metallic plate；What described pairing portion was symmetrical is arranged on two relative sides of metallic plate
On, on two fins being disposed adjacent, a respective pairing portion is combined to form the cavity accommodating parallel portion on evaporation tube, described
The outer wall touching described parallel portion that the inwall of cavity is seamless.
The having the beneficial effect that of this programme：Due to the outer wall being adjacent to described parallel portion that the inwall of described cavity is seamless, steam
Send out pipe omnibearing contact with the pairing portion of fin, raising heat transfer effect；Fin is integrally formed and separates up and down so also not existing
Problem；Also effectively prevented the possibility of leakage of refrigerant simultaneously.Due to using symmetrical pairing portion pairing in adjacent fins
Form cavity, fin can be to be easily arranged in the space between parallel portion on evaporation tube in the form of clamping, and installation is torn open
Unload convenient it is easy to safeguard.
In sum, the present invention can solve the problems, such as leakage of refrigerant and heat exchange efficiency is higher.
Further, described fin is provided with the rib plate perpendicular to described metallic plate, increases the heat exchange area of fin, and raising is changed
The thermal efficiency.
Further, the quantity of described rib plate is 4～8.
Further, it is spaced 3～10mm between the part that described rib plate is parallel to each other.
Further, described evaporation tube is the iron pipe of copper coating.Low cost, good effect of heat exchange.
Brief description
Fig. 1 is the schematic front view of the embodiment of the present invention.
Fig. 2 is the profile at A-A in Fig. 1.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Evaporation tube 1, fin 2, rib plate 3, pairing portion 4.
Embodiment is substantially as shown in drawings：
Refrigerator freezing vaporizer, including evaporation tube 1 and fin 2, the evaporation tube 1 in the present embodiment is the iron pipe of copper coating；As
Shown in Fig. 1, evaporation tube 1 is in S shape bending；Fin 2 is equipped between adjacent parallel portion on evaporation tube 1；Fin 2 includes gold
Belong to plate and a pair semicircular pairing portion 4 integrally formed with metallic plate；As shown in Fig. 2 pairing portion 4 symmetrical be arranged on gold
Belong on two relative sides of plate, on two fins 2 being disposed adjacent, a respective pairing portion 4 is combined to form receiving evaporation tube
The cylindrical cavity of parallel portion on 1, the seamless unoccupied place of inwall of cavity is adjacent to the outer wall of described parallel portion.
Fin 2 is provided with the rib plate 3 perpendicular to described metallic plate, increases the heat exchange area of fin 2, improves heat exchange efficiency.
The quantity of the rib plate 3 on each fin 2 can be 4～8, and the present embodiment preferably adopts 4, between rib plate 3
It is parallel to each other, the desirable 3-10mm in interval, it is preferably 10mm in the present embodiment.
Due to the outer wall being adjacent to described parallel portion that the inwall of described cavity is seamless, evaporation tube 1 is omnibearing and fin 2
Pairing portion 4 contact, improve heat transfer effect；Fin 2 is integrally formed so also there is not detached problem up and down；Simultaneously also effective
Ground has prevented the possibility of leakage of refrigerant.Due to being combined to form cavity using symmetrical pairing portion 4 in adjacent fins 2, fin 2 can
To be easily arranged in the space between parallel portion on evaporation tube 1 in the form of clamping, can be pacified by extracting out/inserting
Assembly and disassembly are unloaded, and are convenient for changing it is easy to safeguard.
