In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.
According to an embodiment of the present invention, a plate heat exchanger 100 is provided. As shown in fig. 1-3, the plate heat exchanger 100 comprises a plurality of disc-shaped heat transfer plates 101 and a fixing plate 102. The disk-shaped heat transfer plate 101 has a substantially rectangular disk shape and includes a base plate and a flange extending upward from the periphery of the base plate. The base plate is provided with two circular coolant flow through holes 1011, 1012 and two circular oil flow through holes 1013, 1014. The coolant flow through hole 1011 and the coolant flow through hole 1012 are arranged at diagonal positions of the base plate, and the oil flow through hole 1013 and the oil flow through hole 1014 are arranged at another pair of diagonal positions of the base plate. Alternatively, the coolant flow hole 1011 and the coolant flow hole 1012, the oil flow hole 1013 and the oil flow hole 1014 may be arranged in other ways, for example, the coolant flow hole 1011 and the coolant flow hole 1012 are arranged on one side of the substrate, and the oil flow hole 1013 and the oil flow hole 1014 are arranged on the other side of the substrate. In this embodiment, the coolant flow through holes 1011 of the topmost disc-shaped heat transfer plate 101 serve as a coolant inlet, and the coolant flow through holes 1012 serve as a coolant outlet.
As shown in fig. 1 and 3, among the four holes of the disk-shaped heat transfer plate 101, there are two holes, such as a coolant flow hole 1011 and a coolant flow hole 1012, having flanges protruding from one side plane of the base plate around the periphery of the holes; the other two holes, oil flow hole 1013 and oil flow hole 1014, have flanges protruding from the opposite side planes of the base plate around the hole's periphery.
Several disc-shaped heat transfer plates 101 are stacked on each other such that the holes correspond to each other, and flanges of the holes of the adjacent disc-shaped heat transfer plates 101 are in contact with each other and flanges of the adjacent disc-shaped heat transfer plates are also in contact with each other, thereby forming coolant channels 104 and oil channels 103, and coolant inlet header 201 and coolant outlet header 202 and oil inlet header and oil outlet header (not shown), which alternate with each other. The coolant inlet header 201 and the coolant outlet header 202 communicate with the coolant channel 104, and the oil inlet header and the oil outlet header communicate with the oil channel 103. In this embodiment, a fin 108 is further disposed in the oil passage 103 to increase the heat exchange area and improve the heat exchange efficiency.
In the present embodiment, the hole diameters of the other coolant flow through holes 1011, 1012 and the oil flow through holes 1013, 1014 are the same, except for the coolant flow through hole serving as the coolant outlet in the topmost disc-shaped heat transfer plate. This makes the process simpler when preparing the disk-shaped heat transfer plate. Of course, alternatively, the bore diameters of the oil flow through holes 1013, 1014 may also be different from the bore diameters of the coolant flow through holes 1011, 1012. In the disc-shaped heat transfer plate at the topmost of the disc-shaped heat transfer plates 101, the aperture of the coolant flow through hole 1012 as the coolant outlet is designed to be smaller than the aperture of the coolant flow through hole 1011 as the coolant inlet to control the flow rate of the coolant. Further, according to the requirements of the client, for example, according to the specific requirements of the client on the flow resistance of the coolant in the plate heat exchanger, simulation can be performed through fluid simulation software according to the functional relationship between the aperture and the cross-sectional area of the coolant outlet and the flow velocity and the flow resistance of the coolant, and the aperture of the coolant flow through hole 1012 in the topmost disc-shaped heat transfer plate is designed to obtain the flow resistance meeting the requirements of the client, so that the flow of the coolant is accurately controlled. It is to be noted here that the hole diameter of the coolant outlet is designed to be smaller than that of the coolant inlet, rather than the hole diameter of the coolant inlet. This is because if the aperture of the coolant outlet is designed to be smaller than the aperture of the coolant inlet, it may result in an insufficient amount of coolant in the plate heat exchanger 100, so that the coolant channels 104 and the coolant inlet header 201 and the coolant outlet header 202 of the plate heat exchanger 100 cannot be filled with sufficient coolant, thereby affecting the heat exchange effect of the plate heat exchanger 100.
In one embodiment, a regulating valve is provided in the coolant outlet for adjusting the bore diameter of the coolant outlet.
In one embodiment, in the bottommost disc-shaped heat transfer plate 101, the coolant flow through hole 1011 serves as a coolant inlet and the other coolant flow through hole 1012 serves as a coolant outlet. The aperture of the coolant flow hole 1012 is smaller than that of the coolant flow hole 1011.
In the present embodiment, as shown in fig. 3, the cover plate 107 is connected to the topmost disc-shaped heat transfer plate of the plurality of disc-shaped heat transfer plates 101. The cover plate 107 is provided with two holes corresponding to the coolant flow through hole 1011 and the coolant flow through hole 1012, respectively, and the hole diameters of these two holes are the same as those of the oil flow through holes 1013, 1014. The coolant inlet pipe 105 and the coolant outlet pipe 106 are connected to corresponding holes of the cover plate 107, respectively.
Alternatively, in another embodiment, a coolant inlet and a coolant outlet corresponding to the coolant flow through holes 1011 and 1012, respectively, are provided in the cover plate 107, and the bore diameter of the coolant outlet is smaller than that of the coolant inlet. In this embodiment, the aperture of the two coolant flow through holes in the topmost disc shaped heat transfer plate may be the same, and/or the aperture of the two coolant flow through holes in the bottommost disc shaped heat transfer plate may be the same.
In the present embodiment, as shown in fig. 1 to 3, one side of the fixing plate 102 is connected to the bottommost disc-shaped heat transfer plate of the plurality of disc-shaped heat transfer plates 101. Two holes corresponding to the oil flow through hole 1013 and the oil flow through hole 1014, respectively, which have the same hole diameter as the oil flow through hole 1013 and the oil flow through hole 1014, are provided in the fixed plate 102.
It will be appreciated that in other embodiments, the coolant inlet and coolant outlet may be provided on the fixing plate 102, with the cover plate 107 sealing and connecting to the topmost disc-shaped heat transfer plate. Optionally, the bore diameter of the coolant outlet is smaller than the bore diameter of the coolant inlet.

At the same time, oil enters the oil channel 103 from the oil inlet via an oil inlet header (not shown), flows through the oil channel 103, and exits the plate heat exchanger 100 through the oil outlet via an oil outlet header. In the plate heat exchanger 100, the coolant exchanges heat with the oil.
The utility model discloses a plate heat exchanger is through the aperture design with coolant outlet for being less than the aperture of coolant entry, through the control that reduces coolant outlet to the realization is to coolant flow's control.
