Description
Technical field
The utility model is related to medical freezing field, and in particular to a kind of heat exchanger plate for refrigeration system.
Background technology
During collection blood, the blood obtained from healthy human body is directly poured into sterile bag, right immediately after
Sterile bag is kept in cold storage, and sterile bag finally is sent into workshop, and quick freezing is carried out to it to -30 DEG C, and freeze-off time is shorter,
More be conducive to the bioactive ingredients in blood such as AcG and platelet cofactor Ⅰ that more preferable curative effect is played in clinic.
A kind of method of prior art is that sterile bag is placed on the shelf of ultralow pressure refrigerator, is entered using cold wind endless form
In the ranks connect and freeze, this mode freeze-off time is long, Blood Center part uniformity is poor, inefficiency, freezing process needs
More colds are consumed, the active ingredient storage rate in blood is low.
Another method is that sterile bag is placed in into heat exchanger plate surface, and cold transfer pipeline is by the small circle in flat board
Flat board interior separations are formed snakelike pipeline by pipe, are wire-shaped contact between pipe and flat board, because the thermal loss of flat board is big, are put down
The temperature of plate surface is inconsistent, can not meet the requirement preserved to active material in blood.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of refrigeration system, and it can solve heat in the prior art
Power board surface temperature is uneven, the low problem of rate of heat exchange.
In order to solve the above problems, the utility model uses following technical scheme：
A kind of heat exchanger plate for refrigeration system, including upper plate and lower plate, the upper plate and lower plate weld form hollow
Heat exchanger plate, the heat exchanger plate is provided with refrigerant inlet and refrigerant outlet, and the upper plate is flat board, and the upper plate is with
It is provided with several welding bars being parallel to each other between plate, the welding bar isolates heat exchanger plate inner panel to form snakelike medium and lead to
Road, the section of the lower plate between described every two adjacent welding bars is circular arc cross-sections.
Further, the welding bar is the distance between adjacent equal two-by-two.
Further, the distance between described every two adjacent welding bars are 40mm.
Further, the thickness of the upper plate is 2mm-3mm, and the thickness of the lower plate is 0.5mm-1mm.
Further, the height of circular arc is 3mm-5mm in the circular arc cross-sections.
Further, the upper plate is formed by connecting with lower plate through the mode of laser welding.
Compared with prior art, heat exchanger plate of the present utility model uses two pieces of stainless steel plates of variable thickness, through laser
Welding procedure makes the two by welding bar close adhesion, and the upper plate of sterile bag of the contact equipped with blood is flat board, and thickness is larger, has
Beneficial to the good contact of blood sterile bag, lower plate for section be welded bar split the multiple to be formed be connected with each other arc-shaped cut
Face, thickness is smaller, and it is connected the snakelike shape medium channel to be formed with upper plate, is conducive to refrigerant logical in the snakelike medium of equal wide
The heat of flat board is fully drawn in road, heat exchanger effectiveness is up to more than 90%.
Brief description of the drawings
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the front view of the utility model heat exchanger plate；
Fig. 2 is sectional view of the utility model heat exchanger plate along A-A.
Wherein, reference is described as follows：Upper plate 1, lower plate 2, circular arc cross-sections 3, refrigerant inlet 4, refrigerant
Outlet 5, snakelike medium channel 6 welds bar 7.
Specific embodiment
As shown in Figures 1 and 2, a kind of heat exchanger plate for refrigeration system, including upper plate 1 and lower plate 2, the upper plate 1
And the welding of lower plate 2 forms hollow heat exchanger plate, the heat exchanger plate is provided with refrigerant inlet 4 and refrigerant outlet 5, it is described on
Plate 1 is flat board, and several welding bars 7 being parallel to each other are provided between the upper plate 1 and lower plate 2, and the bar 7 that welds is by heat exchange
Plate inner panel isolates to form snakelike medium channel 6, and the section of the lower plate 2 between described every two adjacent welding bars 7 is arc-shaped
Section 3.
Wherein, the welding bar 7 is the distance between adjacent equal two-by-two.
Wherein, the distance between described every two adjacent welding bars 7 are 40mm.
Wherein, the thickness of the upper plate 1 is 2mm, and the thickness of the lower plate 2 is 0.5mm.
Wherein, the height of circular arc is 3mm in the circular arc cross-sections 3.
Wherein, the upper plate 1 is formed by connecting with lower plate 2 through the mode of laser welding.
The course of work：Refrigerant enters inside heat exchanger plate through refrigerant inlet 4, along snakelike medium channel 6 to refrigerant
The direction flowing of outlet 5, the sterile bag equipped with blood, because upper plate 1 is flat board, is conducive to aseptic as the outer surface of upper plate 1
