Abstract

The utility model is applicable in the radiating field and provides a heat exchanger with fins and applied to communication cabinets. The heat exchanger is provided with a heat exchanger core; the heat exchanger core includes a plurality of partition plates, a plurality of seals and two air outlets, wherein, the seals are arranged at an open end formed by two adjacent clapboards; the fin is connected between the two adjacent clapboards, and the parts of the fin connected with the clapboards are two planes in parallel. After the structure is adopted, because the parts of the fin connected with the clapboards are the two planes in parallel and the clapboards are plane structures, the welding rate between the fin and the clapboards, and between the clapboards and the seals can be obviously improved, the wind resistance to the heat exchanger core can be further reduced, and thus the heat exchanging effect is effectively improved.

Description

A kind of heat exchanger that has fin
Technical field
The utility model relates to the heat radiation field, relates in particular to a kind of heat exchanger that has fin that is applied to communication cabinet.
Background technology
Along with the develop rapidly of modern communications technology, the quantity of the inner electronic devices and components of installing of communication cabinet and power consumption are always in continuous increase, and be corresponding, and the temperature in the cabinet is inevitably in continuous rising.As everyone knows, the job stability of electronic devices and components and life-span are subjected to Temperature Influence bigger, and therefore, heat dissipation problem becomes one of problem that the mechanics of communication development need at first solves.Heat exchanger under the prior art mainly comprises interior circulating fan, outer circulation blower fan and heat exchanger core body, also is provided with air outlet and dividing plate on the heat exchanger core body, fastens or the bonding mode connection by machinery between the dividing plate.During work, make the air of rack inside and rack air outside form the air circulation of two independences and mutual adverse current respectively by blower fan, thereby make hot-air and cold air carry out heat exchange by the dividing plate on the heat exchanger core body.This heat exchanger has prevented that effectively humid air and dust from entering in the cabinet of server, has protected the electronic devices and components of server inside fully, but also has simple in structure, good manufacturability and advantage such as in light weight.But this counterflow heat exchanger under the prior art exists that heat exchange area is little, the defective of heat exchange poor effect, has been difficult to adapt to the requirement of mechanics of communication development.
This defective at prior art, as illustrated in fig. 1 and 2, recently a kind of heat exchanger occurred, also be provided with fin 11 ' in its heat exchanger core body 1 ', this fin 11 ' has been welded on be connected between aforementioned two adjacent separator 12 ' and with dividing plate 12 ' (referring to Fig. 2).Because the use of fin 11 ' makes heat exchange area be increased greatly, has improved the heat exchange effect effectively.
But the technology after this improvement still exists problems such as not high with dividing plate seam rate, that windage is bigger, and therefore, the heat exchange effect still remains further to be improved.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of heat exchanger that has fin, and the seam rate between its fin and the dividing plate is higher, and windage is less, has better heat exchange effect.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of heat exchanger that has fin is provided, it has heat exchanger core body, this heat exchanger core body comprises some dividing plates, several sealed device and two air outlets, wherein, sealing device is arranged on the openend of two adjacent separator formation, described fin is connected between two adjacent separator, and the position that this fin is connected with dividing plate is two planes that are parallel to each other.
Adopt after such structure, because the part that fin is connected with dividing plate is the plane that is parallel to each other, and dividing plate itself also is a planar structure, seam rate between fin and dividing plate, dividing plate and the sealing device can be significantly improved like this, the windage of this heat exchanger core body also can further be reduced, thereby strengthens the heat exchange effect effectively.
Description of drawings
The structural representation of heat exchanger core body in the heat exchanger that Fig. 1 provides for prior art;
Fig. 2 is the partial cutaway schematic of A-A direction among Fig. 1;
Fig. 3 is the structural representation of a preferred embodiment of the novel middle fin of this reality;
Fig. 4 is the schematic side view of Fig. 3.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 3 and Figure 4, the heat exchanger core body of heat exchanger has some dividing plates, several sealed device, fin 11 and two air outlets in the present embodiment, wherein, sealing device is arranged on the openend of two adjacent separator formation, fin 11 is connected between two adjacent separator, and the position that this fin 11 is connected with dividing plate is two planes that are parallel to each other.Like this, because the part that fin 11 is connected with dividing plate is the plane that is parallel to each other, and dividing plate itself also is a planar structure, therefore, the seam rate between fin 11 and the dividing plate can be significantly improved, and the seam rate between strip of paper used for sealing and the dividing plate is improved, like this, not only can further reduce the windage of this heat exchanger core body, can also reduce leakage of air in the dividing plate, thereby can effectively strengthen the heat exchange effect.
In the present embodiment, fin 11 is bent into plane 121 and inclined-plane 122 forms by sheet material is staggered, and like this, these fin 11 edges are several interlaced triangles 12 with the cross section of the perpendicular direction of dividing plate.
In order further to improve radiating effect, the intersection that looked up in the side of vertical partition plate between described fin 11 and the adjacent fins 11, like this, that heat exchange will become will be more abundant, air-flow is also more smooth and easy, thereby make heat exchange property be utilized.During concrete enforcement, the profile of described fin 11 can be made into different shape as required, is preferably rectangle, trapezoidal or parallelogram.
In order further to reduce thermal resistance, strengthen the heat exchange effect, fin 11 is that the mode by nitrogen-protective soldering or vacuum brazing is welded on the dividing plate, adopts these two kinds of Welder's artistic skills to make the thermal resistance between fin 11 and the dividing plate drop to minimum.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
