The hydraulic oil radiator has the advantages that hydraulic oil flows in a zigzag mode among the holes and with the flow guiding grooves as main lines, and heat exchanging efficiency is improved.
Description
Technical field
The utility model relates to a kind of hydraulic oil radiator, specifically is a kind of hydraulic oil radiator that uses the internal fin flat tube.
Technical background
What existing hydraulic oil radiator adopted is the melodica flat tube, and Fig. 1 is the radial cross-section of melodica flat tube, and the rib of some axial distribution is divided into some through holes with the flat tube wall, and hydraulic oil is flow through by through hole and dispels the heat.The melodica flat tube is the section bar by aluminium alloy extruded generation.Because hydraulic oil is flow through straight by through hole, the path of hydraulic oil and flat tube heat exchange is short, and heat exchange efficiency is lower.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model discloses a kind of hydraulic oil radiator and flat tube thereof and internal fin.
The utility model has adopted following technological scheme:
Internal fin is characterized in that, is axially arranged with some guiding gutters, and the fin body between the guiding gutter is provided with some holes, between the hole and hole and guiding gutter connect.Internal fin is used for being embedded in the flat tube inner chamber.
Flat tube comprises flat tube wall and internal fin as mentioned above, and internal fin closely is entrenched in the flat tube wall.Hydraulic oil is served as theme with guiding gutter, and complications flow through between hole, have improved heat exchange efficiency.
As preferably, the flat tube wall is connected with the chimeric back aluminium soldering of internal fin, with the increase join strength.
Hydraulic oil radiator is characterized in that, comprises upper and lower cover plate and heat radiation core body;
The heat radiation core body comprises flat tube and the fin that arrange the space, and heat radiation core body the right and left is provided with side plate, and the heat radiation core body is provided with upper and lower mainboard in two ends up and down;
Upper cover plate and last mainboard constitute the upper chamber of sealing, and lower cover plate constitutes the lower oil chamber that seals with following mainboard, and the flat tube of heat radiation core body is communicated with upper chamber and lower oil chamber;
Upper chamber is connected with filler opening, and lower oil chamber is connected with oil outlet;
Described flat tube is aforesaid flat tube.
As preferably, filler opening, oil outlet are communicated with upper chamber and lower oil chamber by pipe fitting respectively, and filler opening and oil outlet position are adjoining, thereby have made things convenient for the allotment of installation procedure and installing space.
As preferably, be respectively equipped with oil filler and oil drain out in the upper and lower grease chamber.
As preferably, in the upper and lower grease chamber and/or side plate be provided with mounting bracket.
The advantage of the utility model hydraulic oil radiator is that hydraulic oil is served as theme with guiding gutter, and complications flow through between hole, have improved heat exchange efficiency.

Number in the figure: mainboard, 7-filler opening, 8-oil outlet, 9-heat radiation core body, 10-pipe fitting, 11-mounting bracket, 12-flat tube wall, 13-rib, 14-side plate, 15-upper cover plate, 16-oil filler, 17-oil drain out under 1-guiding gutter, 2-hole, 3-fin body, 4-lower cover plate, the last mainboard of 5-, the 6-.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Hydraulic oil radiator as shown in Figure 3, comprise upper and lower cover plate 15 and 4 and the heat radiation core body 9;
The heat radiation core body comprises flat tube and the fin that arrange the space, and heat radiation core body the right and left is provided with side plate 14, and the heat radiation core body is provided with upper and lower mainboard 5 and 6 in two ends up and down;
Upper cover plate and last mainboard constitute the upper chamber of sealing, and lower cover plate constitutes the lower oil chamber that seals with following mainboard, and the flat tube of heat radiation core body is communicated with upper chamber and lower oil chamber;
Filler opening 7, oil outlet 8 are communicated with upper chamber and lower oil chamber, the adjoining state of filler opening and oil outlet position by pipe fitting 10 respectively; Be respectively equipped with oil filler 16 and oil drain out 17 in the upper and lower grease chamber; Upper and lower grease chamber is provided with mounting bracket 11;
Described flat tube comprises flat tube wall and internal fin; Internal fin is axially arranged with some guiding gutters 1, and the fin body between the guiding gutter is provided with some holes 2, between the hole and hole and guiding gutter connect; Internal fin closely is entrenched in the flat tube wall, and is connected with the aluminium soldering of flat tube wall.
The working principle of hydraulic oil radiator is as follows:
Oil flows into upper chamber by filler opening, flows into lower oil chamber by flat tube, and forms circulation, enters upper chamber by filler opening again; Simultaneously, under the driving of blower fan, cool air is passed by the space between flat tube and fin, thereby the oil in the flat tube is cooled off.
Oil has loss in cyclic process, can carry out repairing by oil filler; Every changing oil of needing after a while in order to avoid well cuts is too many, is opened oil drain out and discharged old oil, and adds clean oil by oil filler.
