Abstract
The utility model discloses a double-flow-path heat exchanger end enclosure which comprises a heat exchanger core, heat exchanger end enclosures and baffle plates, wherein the heat exchanger end enclosures are connected to both sides of the heat exchanger core, external baffle plates are arranged outside the left heat exchanger end enclosure, a baffle plate which separates two end enclosures is mounted inside the left heat exchanger end enclosure, one end of the baffle plate is fixed in the heat exchanger end enclosure through spot welding, the other end of the baffle plate is fixedly and hermetically inserted into the heat exchanger core, and the two sides of the baffle plate are respectively provided with a liquid inlet and a liquid outlet. The baffle plates are hermetically connected with the heat exchanger core. The baffle plates are slightly higher than the end enclosures, and the heat exchanger core is provided with concave grooves corresponding to the baffle plates, wherein the concave grooves are used for inserting the baffle plates. The double-flow-path heat exchanger end enclosure has a simple structure and adopts welded baffle plates, so that the welding difficulty is lowered, and the welding process is facilitated.
Description
Technical field
The utility model relates to the heat exchange equipment field, particularly relates to exchanger head.
Background technology
Heat exchanger has been widely used in fields such as aviation, automobile, diesel locomotive, engineering machinery, air compression, air separation, petrochemical industry, air-conditioning, refrigeration at present.Radiator can be divided into single process, double-current journey and multipaths radiator according to flow process.Traditional radiator is generally single process, and is as shown in Figure 1, and promptly end socket is installed on the core body both sides respectively, imports and exports flange or take over to be installed in respectively on the end socket of both sides.Fluid gets into end socket from left interface, behind the internal channel of flowing through from right end socket to exporting flow process, fluid is one-way flow from left to right, i.e. single process.Though double-current pass heat exchanger is also arranged, as shown in Figure 2, after fluid flows into from the left side bottom head, through core body to right part end socket, the inflow core body that turns back again, upper cover flows out from the left side.Fluid has a process of turning back in radiator body, this is double-current pass heat exchanger, be different from single process heat exchanger part just be the left side up and down between two end sockets welding not connected, middlely separate by a baffle plate.Above-mentioned double-current pass heat exchanger, adding in actual production has a lot of inconveniences man-hour, and low head needs separate machined, boring on the left side; With the middle baffle plate welding, need the many places welding again, the welding difficulty is higher; Simultaneously because the fire damage in the welding process causes metal fatigue; Service life is short, and it is numerous and diverse that end socket is changed frequent whole operation, and quality stability is not high.
The utility model content
The utility model has been to overcome the defective of prior art, and a kind of double-current pass heat exchanger end socket of simple in structure, long service life is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Comprise heat exchanger core body, exchanger head and baffle plate; Said heat exchanger core body both sides all are connected with exchanger head; The described exchanger head outer setting in left side have outer baffle, inside be equipped with one separate two end sockets baffle plate; Said baffle plate one end is fixed in the exchanger head through spot welding, and said baffle plate other end fixing seal is plugged in heat exchanger core body, and said baffle plate both sides are respectively inlet, liquid outlet.
Said baffle plate and heat exchanger core body are tightly connected.
Said height of baffle plate is a little more than end socket, and the corresponding baffle plate of said heat exchanger core body place has the groove that baffle plate snaps in.
Compared with prior art, the utlity model has following beneficial effect:
The utility model end enclosure structure is simple, good airproof performance, long service life.Easy to process, adopt the welding baffle plate, reduce the welding difficulty.

Fig. 2 is the structural representation of existing double-current pass heat exchanger;
Fig. 3 is the structural representation of the utility model double fluid pass heat exchanger end socket.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Shown in Fig. 2-3; Double fluid pass heat exchanger end socket; Comprise exchanger head 1, heat exchanger joint 2 and 3, baffle plate 6; And heat exchanger core body 4, the exchanger head 1 in left side is an end socket integral body, the outside both sides up and down of end socket 1 be welded with outer baffle 5, inside be equipped with one separate two exchanger head 1 baffle plate 6.Baffle plate 6 one ends are fixed in the exchanger head 1 in left side through spot welding, and baffle plate 6 both sides are respectively the inlet and the liquid outlet of heat exchanger joint, are convenient to inlet, liquid outlet is installed in on a slice flange.Baffle plate 6 other end fixing seals are plugged on the heat exchanger core body 4, and baffle plate 6 height have groove a little more than exchanger head 1 on the strip of paper used for sealing at heat exchanger core body 4 corresponding baffle plate places, and groove and baffle plate 6 ends are wide isometric, and connection between the two is sealed and matched.When installing, the part that baffle plate 6 slightly exceeds exchanger head 1 directly inserts in this end socket groove, thus the phenomenon of avoiding two side liquids to leak through the baffle plate string.
The utility model double fluid journey end socket, simple in structure, procedure is few, and welding sequence is few, has improved heat exchanger whole reliability and service life.
The above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
