Abstract

The utility model provides an evaporator cooling fin main board directing at the defects that in prior art, a cooling fin main board is poor in cooling effect and easy to displace when being welded. The main board comprises a main board body and diversion holes which are formed in one end of the main board body, wherein at least two lines of diversion strips and at least two rows of diversion strips are arranged on the upper surface of the main board body, the diversion strips are arranged in a parallel, slant, and interval mode, and the diversion strips are arranged inclined from the ends of the diversion holes inclining to the tail end of the main board body. By the adoption of the evaporator cooling fin main board, cooling effect is good and displacement is prone to occurring during welding.

Description

A kind of evaporator fin mainboard

Technical field

The utility model relates to a kind of evaporimeter, particularly relates to a kind of evaporator fin mainboard.

Background technology

Present widely used evaporimeter, contact on its fin mainboard is an examples of dot shaped, just, is provided with the point-like contact in the surface distributed of every module radiator mainboard, adopt the radiator mainboard of point-like contact because its contact is the plum blossom shape distribution, the passage complications that make the steam circulation, circulation passage stream is stifled too small, causes poor refrigerating efficiency, in addition, because two sheet heat radiators are fitted together Shi Weidian contact by contact sets,, cause product percent of pass low so easily misplace during welding.

The utility model content

The purpose of this utility model is at the radiator mainboard poor refrigerating efficiency of prior art, the deficiency that easily misplaces when welding, to be difficult for the evaporator fin mainboard that misplaces when a kind of good refrigeration effect and welding are provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of evaporator fin mainboard, described mainboard comprises the pod apertures that mainboard body and mainboard body one end are provided with, described mainboard body upper surface is provided with at least two row two row flow guide bars, described flow guide bar is parallel, tilt and be provided with at interval, and described flow guide bar is obliquely installed by the tail end of water conservancy diversion nose end to the mainboard body;

Described each row flow guide bar is broken into short flow guide bar by the long flow guide bar of row and forms;

Described mainboard body is separated into mainboard left side body and the right body of mainboard by diversion column, is respectively arranged with delegation's two described flow guide bar of row and described pod apertures at least on described mainboard left side body and the right body of described mainboard;

The inclination angle a of described flow guide bar is 19.5 °-20.5 °;

Tail end at described mainboard body is provided with the contact;

The distribution triangular in shape of described contact;

Described flow guide bar is formed to described upper surface projection by described mainboard body.

Adopt the radiator mainboard of the utility model structure, because the contact is strip and tilt distribution, the circulation passage that makes the contact form is smooth and easy, make good heat dissipation effect, heat dispersion has improved 5%, and owing to when two mainboards fit together, increased the contact area of the two, so be difficult for dislocation during welding, welding effect is good, and qualification rate has improved 10%, and production efficiency has improved 10%.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is made explanation further:

As Figure 1-3, evaporator fin mainboard of the present utility model, comprise mainboard body 3, be provided with pod apertures 1 at an end of mainboard body 3, the steam that Gong condenses flows out, upper surface at mainboard body 1, be provided with flow guide bar 4, this flow guide bar 4 is minimum to be two row, two row, and each flow guide bar 4 is obliquely installed, all flow guide bars are parallel to each other, and face flow guide bar mutually and are provided with at interval.

In order to make the water conservancy diversion better effects if, an end of deflector is provided with two pod apertures 1, by diversion column 2 mainboard body 3 is divided into symmetrical left and right two parts, and these two parts are respectively mainboard left side body and the right body of mainboard.Be provided with minimum two row, two row flow guide bars 4 on the right body of mainboard left side body and mainboard.

The flow guide bar of each row is preferably blocked to be provided with by the long flow guide bar on same oblique line and forms, and the long flow guide bar of the delegation that just all flow guide bars are obliquely installed by being parallel to each other is formed up to the short flow guide bar of few two row through interrupting.The position of flow guide bar is set like this, can make each row flow guide bar 4 form the level and smooth passage 6 that is obliquely installed,, mark passage 6 with arrow in the drawings for the ease of observing, but arrow is not represented the trend of passage, and these level and smooth passages 6 make the steam that condenses on the mainboard flow to pod apertures 1 swimmingly.

In the position as Fig. 1, diversion column is horizontally disposed with, and flow guide bar is by a angle that tilts from left to right on top-down direction, and a is advisable with 19.5 °-20.5 °.

In order to weld more firmly, prevent that pad from popping from the tail end 7 of mainboard, the short point that the length of diversion column will design, be shorter than the distributed area of flow guide bar, be positioned at the position of the center line of mainboard, tail end 7 at mainboard is provided with contact 5., the rectangular triangle of arrangement of best contact 5, and one right-angle side and water conservancy diversion are annotated post and are located on the same line.The fin mainboard is set like this, and when two mainboards intersected welding, surface soldered point was more firm, and the freezing liquid trend is more even, and radiating effect is better.

For weight reduction, flow guide bar is protruded to the mainboard upper surface by the mainboard body and forms.

During use, two mainboard bodies 1 are welded together relatively, each corresponding flow guide bar, contact and pod apertures are oppositely arranged, like this, because it is not,, easy to crack between two mainboard bodies so two mainboard bodies weld more firmly by contact of flow guide bar face or line contact.Because steam flows to pod apertures 1 at the passage 6 of the inclination that each flow guide bar forms, gush stifledly so be difficult for forming, make radiating effect better.
