Abstract

A plate fin type oil cooler is an aluminium heat exchanger, comprises an aluminium plate fin type core composed of clapboards, inside/outside fins, inside/outside seal and side plates on both sides; an upper and a lower end sealing cavity; and joints welded on the sealing cavities. a channel communicating the inside and outside is disposed on every third interval of the clapboards of the core, both sides are provided with side plates; the channels are intersected with each other, arranged by layers and mounted by clamping. The oil cooler is characterized in that: the outside seal is a grooved structure; both outer sides of the core are provided with two continuous outside channels. The oil cooler can relieve the stress concentration phenomenon between an end outside seal and a clapboard effectively; at the same time, the stress concentration phenomenon at the corners caused by high temperature avoids the crack of an end clapboard of the inside channel and the tearing of a solder joint, thereby prevents the leakage of an inside channel.

Description

A kind of plate-fin oil cooler
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of plate-fin heat exchanger as oil cooler.
Background technology
Plate-fin heat exchanger is widely applied to all trades and professions now because of its heat exchange efficiency height, compact conformation, advantage such as easily manufactured.Main manufactured materials is preferably aluminium alloy, and still, the aluminum plate-fin heat exchanger as oil cooler also can't satisfy long-time running under the operating mode more than 120 degrees centigrade at present.Reason is, oil cooler in use, because temperature is higher, thermal expansion amount is bigger, easily in aluminum plate-fin type core body end and the bight stress concentration phenomenon is arranged, cause this position dividing plate and the phenomenon that short strip of paper used for sealing place solder joint is torn, dividing plate ftractures to take place, cause the leakage of heat exchanger, have a strong impact on the safe handling of oil heat exchanger.
The utility model content
The utility model is intended to overcome the described shortcoming of background technology, provide a kind of simple in structure, radiating efficiency is high, the plate-fin heat exchanger of the dependable performance that can at high temperature use.
To achieve these goals, the utility model is by the following technical solutions:
Comprise the aluminum plate-fin type fuse, be welded on the end socket cavity of the upper and lower end on the fuse, and be welded on the interface on the end socket cavity.The aluminum plate-fin type fuse mainly is made up of the side plate on dividing plate, interior outside fin, interior outer seal and both sides.Between per two dividing plates, place inboard fin and inboard strip of paper used for sealing, form an interlayer, become internal channel, between per two dividing plates, place outside fin and outer seal, form another interlayer, become outer tunnel.Side plate is placed on both sides, and the internal and external channel cross stratification is placed and clamped.It is characterized in that: aluminum plate-fin type fuse outer seal adopts reeded structure, and the outer both sides of this fuse are arranged two outer tunnels continuously.
The flat shape of the groove of described outer seal, preferably: pit of indent, centre are recessed inward again, progressively receive the end to be trapezoidal, and a circle greater than the two bottom sides distance is set in the bottom, and circular and trapezoidal the connection is provided with chamfering.
Oil cooler of the present utility model can effectively be alleviated the stress concentration phenomenon between end outer seal and dividing plate, the stress concentration phenomenon of effectively alleviating bight Yin Gaowen and producing, avoid the cracking of end dividing plate and the tearing of solder joint of inner channel, prevent the leakage of internal channel.

Fig. 4, the preferable shape plane of outer seal 13 of the present utility model.
Among the figure, 1---the aluminum plate-fin type fuse, 2---the end socket cavity, 3,4---interface, 5---outer tunnel, 11---inboard strip of paper used for sealing, 12---inboard fin, 13---outer seal, 14---outside fin, 15---dividing plate, 16---side plate.
The specific embodiment
Below in conjunction with accompanying drawing, concrete structure of the present utility model is described.
As shown in Figure 1, plate-fin oil cooler of the present utility model is a kind of aluminum plate-fin heat exchanger, has aluminum plate-fin type fuse 1, be welded on the end socket cavity 2 of the upper and lower end on this fuse 1, and be welded on 3,4, one imports of interface on the end socket cavity 2, an outlet.
The structure of aluminum plate-fin type fuse 1 such as Fig. 2, shown in Figure 3 mainly are made up of the side plate 16 on dividing plate 15, inboard fin 12, outside fin 14, inboard strip of paper used for sealing 11, outer seal 13 and both sides.Place inboard fin 12 and inboard strip of paper used for sealing 11 on 15 on per two dividing plates, constitute an interlayer: internal channel; Between per two dividing plates, place outside fin 14 and outer seal 11, form another interlayer: outer tunnel 5; Inside and outside passage cross stratification is placed and is clamped, and becomes plate-fin fuse 1 after the vacuum brazing, and side plate is placed on both sides.
Especially as shown in Figure 3: in the utility model, aluminum plate-fin type fuse 1 outer both sides are arranged two outer tunnels 5 continuously.
Aluminum plate-fin type fuse outer seal adopts reeded structure.
Fig. 4 is the preference of the groove of outer seal 13, and flat shape is: pit of indent, centre continue inward recessed again, progressively receive the end to be trapezoidal, and a circle greater than the two bottom sides distance is set in the bottom, and circular and trapezoidal the connection is provided with chamfering.It is tubaeform visually to be inverted loudspeaker round bottom.
It is pointed out that at last present embodiment is not unique implementation of the present utility model, those skilled in that art, without creative work, the conspicuous variation of having done all should belong to protection domain of the present utility model.
