Abstract
The utility model discloses a heat exchange plate layer for a freeze dryer. The heat exchange plate layer comprises a border, an upper panel and a lower panel, wherein the upper panel and the lower panel are buckled on the border; the border comprises two transverse border strips and two longitudinal border strips; more than two square pipes are arranged side by side in the border at proper intervals; the square pipes are properly shorter than the longitudinal border strips; one end of each square pipe is pressed against one transverse border strip; one end of the other adjacent square pipe is pressed against the transverse border strip on the other side; the square pipes are fixed with the upper panel and the lower panel through laser welding; and an inlet and an outlet of coolants are formed on the border. According to the heat exchange plate layer, coolant channels are formed by the border and the square pipes; the square pipes are fixed with the upper panel and the lower panel through laser welding; therefore, the heat exchange plate layer is simple in structure and convenient to machine and manufacture; and furthermore, the heat exchange plate layer has the characteristics of high freeze drying efficiency, uniform temperature and the like.
Description
Technical field
The utility model relates to a kind of heat exchange flaggy that is used for freeze dryer, belongs to the freeze drying field.
Background technology
Freeze dryer is widely used in fields such as medicine, biological products, food, blood product, active material field, and its application scale and field are also in constantly enlarging.
Existing freeze dryer has freeze drying box, in freeze drying box, is provided with to be used for heat exchange and product is carried out the heat exchange flaggy that freeze-drying is handled.The heat exchange flaggy needs a large amount of refrigerants to be passed through in the middle of the heat exchange flaggy, thereby low temperature environment is provided for the heat exchange flaggy.And the common structure more complicated of existing heat exchange flaggy is not easy processing.
The utility model content
To the problem that prior art exists, the purpose of the utility model is to provide a kind of heat exchange flaggy that is used for freeze dryer, and is not only simple in structure, and processing easily.
A kind of heat exchange flaggy that is used for freeze dryer of the utility model comprises: frame be fastened on top panel and the lower panel on the frame; This frame comprises 2 horizontal mouldings and 2 vertical mouldings; Suitable at interval distance is arranged side by side the square tube more than 2 in said frame; The length of square tube is suitably less than the length of said vertical moulding; One end of said square tube is resisted against on 1 horizontal moulding, and an end of other 1 square tube of facing mutually is resisted against on the horizontal moulding of an other side; Said square tube and top panel, lower panel are fixed together through Laser Welding; On said frame, also offer the entrance and exit of refrigerant.
Preferably, said square tube is hollow square tube.
Preferably, two of said square tube end faces are the inclined-plane with suitable angle.
The utility model adopts frame and square tube to form refrigerant passage, and through the mode of Laser Welding square tube and top panel, lower panel is fixed together, and is not only simple in structure, and is convenient to processing and making.Characteristics such as in addition, it is high that the utility model also has freeze-drying efficient, and temperature is even.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A-A to the cross section enlarged diagram.
The specific embodiment
Like Fig. 1, shown in 2, the utility model comprises: frame 1 and the top panel 2 and lower panel 3 that are fastened on the frame 1.Frame 1 comprises 13,14 and 2 vertical mouldings 11,12 of 2 horizontal mouldings.At interval suitably distance has been arranged side by side 5 square tubes 4 in frame 1, and the length of square tube 4 is suitably less than the vertical length of moulding 11, so that form the passage of refrigerant circulation.One end of square tube 4 is resisted against on the horizontal moulding 13, and an end of other 1 square tube 4 of facing mutually is resisted against on the horizontal moulding 14 of an other side.Like this, just formed the passage of refrigerant circulation.Square tube 4 and top panel 2, lower panel 3 are fixed together through Laser Welding.In addition, on frame 1, also offer the inlet 5 and outlet 6 of refrigerant.
Because the utility model employing frame 1 forms refrigerant passages with square tube 4, and through the mode of Laser Welding square tube 4 and top panel 2, lower panel 3 is fixed together, and is not only simple in structure, and be convenient to processing and making.
In the utility model embodiment, square tube 4 is hollow square tube, and two end faces of square tube 4 are the inclined-plane with suitable angle, for example 45 ° inclined-plane roughly.Like this, refrigerant can also flow through from the hollow of square tube 4, can further improve the refrigerating efficiency of refrigerant.Therefore, the utility model freeze-drying efficient is high, and temperature is even.
