Technical field
The utility model relates to field of heat exchangers, relates in particular to a kind of package backplate for heat exchanger and the case tube heat exchanger that comprises this backplate.
Background technology
In present air conditioner industry package production process, in order to prevent that Decrepitation Phenomena from appearring in backplate in welding process, in the time of welding backplate, backplate can not be welded completely, need to reserve an intersegmental gap.Thereby cause welding fabrication second-rate, the time easily occurs that once long weld splits and comes off, and backplate fixed effect worse and worse.
Therefore designing a kind of package backplate that can ensure good welds effect is very urgent demand.
Utility model content
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of package backplate and case tube heat exchanger.
The technical solution of the utility model is as follows:
A kind of package backplate, comprises backplate main body, in described backplate main body, is provided with at least one passage.
In an embodiment, described at least one, passage is arranged on the center of described backplate main body therein.
In an embodiment, the quantity of described passage is multiple therein, and described multiple passage non-uniform Distribution are in described backplate main body.
In an embodiment, described at least one, passage is arranged on the position near welding starting point in described backplate main body therein.
In an embodiment, the area of described passage is 300 square millimeters to 800 square millimeters therein.
Therein in an embodiment, described passage be shaped as circle, triangle or rectangle;
Described backplate main body is flat board or arc.
Therein in an embodiment, the gross area of described passage account at the most described backplate main body the gross area 1%.
The utility model also provides a kind of case tube heat exchanger, comprises heat exchanger shell, also comprises package backplate as above, described package backplate and the welding of described heat exchanger shell.
The beneficial effects of the utility model are: package backplate of the present utility model is provided with passage, the hot gas producing in welding process like this can be discharged by passage, can avoid the Decrepitation Phenomena in welding process, when package backplate welds like this, just backplate can be welded completely, welding quality is higher, package backplate good fixing effect.
Brief description of the drawings
Fig. 1 is the overall schematic of an embodiment of package backplate of the present utility model;
Fig. 2 is the overall schematic of another embodiment of package backplate of the present utility model.
Detailed description of the invention
In order to make object, technical scheme and the advantage of package backplate of the present utility model and case tube heat exchanger clearer, below in conjunction with concrete drawings and the specific embodiments, the utility model is further elaborated.
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of package backplate, and this package backplate comprises backplate main body 100, in described backplate main body, is provided with passage 200.
The problem that backplate can not be welded completely while welding in order to solve, the present embodiment is provided with passage in backplate main body, the hot gas producing when welding can be discharged by passage, so just can avoid the Decrepitation Phenomena occurring in welding process, when welding, just package backplate can be welded completely, not need to reserve space, the weldquality after welding is high, the phenomenon that there will not be weld to split or come off, package backplate fixed effect is good.
Preferably, as a kind of embodiment, referring to Fig. 2, the quantity of described passage 200 is multiple, and described multiple passage 200 non-uniform Distribution are in described backplate main body 100.In the present embodiment, multiple passages can be set in backplate main body, multiple passages are uneven distribution in backplate main body, wherein more in the quantity of the local passage near backplate welding starting point, facilitate like this hot gas producing in welding process to discharge fast, can lack in the quantity of the passage of the end of welding position.The manufacturing process that the position of passage and quantity can rationally arrange package backplate is rationally set.
Preferably, referring to Fig. 2, described at least one, passage 200 is arranged on the center of described backplate main body.The present embodiment is particularly useful for the situation that backplate main body is non-tablet; because backplate main body is shaped form or arc; the hot gas producing when package backplate welds so generally concentrates on the center of backplate; conventionally the center position of backplate main body is the concentrated position of hot gas, and hot gas just can be discharged from passage fast like this.
Preferably, as a kind of embodiment, in the present embodiment, passage is arranged on the position near welding starting point in described backplate main body described at least one.The hot gas that convenient like this welding starts to produce is discharged fast.
Preferably, as a kind of embodiment, referring to Fig. 1, described passage 200 is one, and described passage 200 is arranged on the center of described backplate main body 100.In the time a passage being only set in backplate main body, the location optimization of passage is arranged on the center of backplate main body, can make like this hot gas producing in welding process all discharge fast by passage.
Preferably, as a kind of embodiment, the area of described passage 200 is 300 square millimeters to 800 square millimeters.The size of passage can arrange according to actual needs, but the size in optimizing breathing hole is at 300 to 800 square millimeters.
Preferably, as a kind of embodiment, described passage 200 be shaped as circle, triangle or rectangle.When passage be shaped as circle time, the diameter of passage should be at 20mm to 50mm.
Preferably, as a kind of embodiment, the gross area of described passage account at the most described backplate main body the gross area 1%.The hot gas that setting both can make welding process produce is like this discharged fast, can not affect again the intensity of package backplate.
Preferably, as a kind of embodiment, described backplate main body 100 is flat board or arc.The shape of backplate main body can be determined according to actual needs.
As a kind of preferred application, the utility model also provides a kind of case tube heat exchanger, comprises heat exchanger shell, also comprises the package backplate described in above any embodiment, described package backplate and the welding of described heat exchanger shell.
The installation method of the package backplate in the utility model, comprises the steps:
S100: make passage 200 on described package backplate;
S200: the predetermined installation site that described package backplate is placed on to case tube heat exchanger;
S300: adopt welding gun to weld along the edge of package backplate until the edge of package backplate is all connected with the shell of described heat exchanger.
Wherein, in step S300, welding preferably starts welding from the edge of the package backplate near described passage.The hot gas that convenient like this welding produces is discharged rapidly.
The utility model is provided with special passage on package backplate, weld seam one-shot forming, and high conformity, weld appearance is full, attractive in appearance, ensures product appearance quality.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claim.
