Based on this, it is necessary to provide a heat exchanger and a cooling system to solve the problem that it is difficult for the heat exchanger to significantly reduce the pressure drop of the medium without reducing the heat dissipation effect.

The heat exchanger provided by the application comprises a plurality of core plate assemblies which are arranged in a stacked manner, wherein the heat exchanger is provided with a first collecting port, a second collecting port and an intermediate collecting port which penetrate through the core plate assemblies along the stacking direction of the core plate assemblies and are respectively communicated with the plurality of core plate assemblies, the number of the intermediate collecting port is one or more, the first collecting port and the second collecting port are arranged at two ends of the heat exchanger which are oppositely arranged, the intermediate collecting port is arranged between the first collecting port and the second collecting port, and the intermediate collecting port, the first collecting port and the second collecting port can be mutually communicated. And the length of the channel from the middle flow collecting port to the first flow collecting port and the length of the channel from the middle flow collecting port to the second flow collecting port are smaller than the length of the channel between the first flow collecting port and the second flow collecting port.

In one embodiment, the heat exchanger further comprises a first spacer ring, a second spacer ring and an intermediate spacer ring, wherein the first spacer ring is arranged at the first collecting port and is respectively connected with the adjacent core plate assemblies, the second spacer ring is arranged at the second collecting port and is respectively connected with the adjacent core plate assemblies, and the intermediate spacer ring is arranged at the intermediate collecting port and is respectively connected with the adjacent core plate assemblies.

Compared with the prior art, the heat exchanger and the cooling system provided by the application have the advantages that the first collecting port, the second collecting port and the middle collecting port can be used as the liquid inlet or the liquid outlet of the heat exchanger, for example, when the middle collecting port is the liquid inlet of the heat exchanger and the first collecting port and the second collecting port are the liquid outlet of the heat exchanger, the medium enters each core plate assembly from the middle collecting port, then flows in the core plate assembly towards the first collecting port and the second collecting port respectively, and leaves the heat exchanger through the first collecting port and the second collecting port respectively. Thus, the channels of the medium in the core plate assembly are divided into two channels, and one channel is: from the intermediate manifold to the first manifold, the other channel is: from the intermediate collecting port to the second collecting port. Since the length of the passage from the intermediate manifold to either the first manifold or the second manifold is less than the length of the passage between the first manifold and the second manifold. Therefore, the lengths of the two channels are shorter than the length of the channel from the first collecting port to the second collecting port. That is, the flow length of the medium in both channels is reduced compared to the flow from the first header directly to the second header. In this way, the pressure drop of the medium in the two channels must be reduced.

Further, as known from the mathematical knowledge, the sum of the lengths of the two channels is greater than or equal to the length of the channel from the first collecting port to the second collecting port. That is, the overall flow length of the medium within the core assembly is not shortened, and as such, the heat exchange effect of the heat exchanger is not reduced.

When the middle collecting port is a liquid outlet of the heat exchanger, the first collecting port and the second collecting port are liquid inlets of the heat exchanger, a channel of a medium in the core plate assembly is divided into two channels, and one channel is: from the first collecting port to the middle collecting port, the other channel is: from the second to the intermediate collector. Likewise, the flow length of the medium in both channels in this embodiment is reduced compared to the flow from the first header directly to the second header. Thus, the pressure drop of the medium in the two channels must be reduced in this embodiment. And, the sum of the lengths of the two channels in the present embodiment is greater than or equal to the length of the channel from the first collecting port directly to the second collecting port. That is, the overall flow length of the medium within the core assembly is not shortened, and as such, the heat exchange effect of the heat exchanger is not reduced.

In summary, the heat exchanger provided by the application has the advantages that the pressure drop of the medium is obviously reduced, and the heat dissipation effect is not reduced.

The plate-fin type oil cooler is generally formed by stacking a plurality of core plate assemblies, and two ends of each core plate assembly are respectively provided with a through hole for medium to flow, i.e. medium flows in from one end of the core plate assembly and flows out from the other end of the core plate assembly. And the core plate assembly consists of an upper chip and a lower chip, and fins are further arranged in the core plate assembly to improve the heat dissipation effect.

Generally, the fins of the oil cooler generally have a Z-type (the flow direction of the medium is parallel to the tooth-shaped direction) and an H-type (the flow direction of the medium is perpendicular to the tooth-shaped direction), the Z-type fins generally have lower pressure drop, the heat dissipation effect is inferior to that of the H-type, and the heat dissipation effect of the H-type is better, but there is higher pressure drop.

Referring to fig. 1-4, in order to solve the above-mentioned problems, the present application provides a heat exchanger capable of significantly reducing pressure drop of a medium without reducing heat dissipation effect, the heat exchanger includes a plurality of core plate assemblies 100 stacked together, the heat exchanger is provided with a first collecting port 210, a second collecting port 220 and an intermediate collecting port 230 penetrating along a stacking direction of the core plate assemblies 100 and respectively communicating with the plurality of core plate assemblies 100, the number of the intermediate collecting port 230 is one or more, the first collecting port 210 and the second collecting port 220 are disposed at two opposite ends of the heat exchanger, the intermediate collecting port 230 is disposed between the first collecting port 210 and the second collecting port 220, and the intermediate collecting port 230, the first collecting port 210 and the second collecting port 220 can be mutually communicated. And, the channel length of the intermediate manifold 230 to the first manifold 210 and the channel length of the intermediate manifold 230 to the second manifold 220 are both less than the channel length between the first and second manifolds 210, 220.

It should be noted that, the openings at one end of the first collecting port 210, the second collecting port 220 and the middle collecting port 230 are all provided with a cover plate 410, so that the first collecting port 210, the second collecting port 220 and the middle collecting port 230 can realize single-side sealing, and the cover plate 410 can enhance the compressive strength of the bottom of the heat exchanger. The openings at the other ends of the first and second fluid collecting ports 210 and 220 and the middle fluid collecting port 230 are respectively provided with a flange 420 for connecting external pipes.

When the number of the intermediate fluid collecting ports 230 is one, the intermediate fluid collecting ports 230 can be respectively connected to the first fluid collecting port 210 and the second fluid collecting port 220, and when the number of the intermediate fluid collecting ports 230 is plural, the plurality of intermediate fluid collecting ports 230 can be respectively connected to the first fluid collecting port 210 and the second fluid collecting port 220, and the intermediate fluid collecting ports 230 can also be mutually connected.

Also, it is understood that the first and second headers 210, 220 and the intermediate headers 230 may each serve as a liquid inlet or a liquid outlet of the heat exchanger, for example, when the intermediate headers 230 are liquid inlets of the heat exchanger and the first and second headers 210, 220 are liquid outlets of the heat exchanger, medium enters each core plate assembly 100 from the intermediate headers 230, then flows toward the first and second headers 210, 220, respectively, within the core plate assembly 100 and exits the heat exchanger through the first and second headers 210, 220, respectively. Thus, the channels of the medium within the core assembly 100 are divided into two channels, one channel being: from the intermediate manifold 230 to the first manifold 210, another passage is: from the intermediate manifold 230 to the second manifold 220. Since the passage length of the intermediate manifold 230 to either the first manifold 210 or the second manifold 220 is less than the passage length between the first manifold 210 and the second manifold 220. Thus, the length of both channels is shorter than the length of the channels from the first header 210 to the second header 220. That is, the flow length of the medium in both channels is reduced compared to the flow from the first header 210 directly to the second header 220. In this way, the pressure drop of the medium in the two channels must be reduced.

Further, as known in the mathematical sense, the sum of the lengths of the two channels is greater than or equal to the length of the channel from the first manifold 210 directly to the second manifold 220. That is, the overall flow length of the medium within the core assembly 100 is not shortened, and as such, the heat exchange effect of the heat exchanger is not reduced.

When the middle collecting port 230 is a liquid outlet of the heat exchanger and the first collecting port 210 and the second collecting port 220 are liquid inlets of the heat exchanger, the channels of the medium in the core plate assembly 100 are divided into two channels, and one channel is: from the first manifold 210 to the intermediate manifold 230, another passage is: from the second manifold 220 to the intermediate manifold 230. Likewise, the flow length of the medium in both channels in this embodiment is reduced compared to the flow from the first header 210 directly to the second header 220. Thus, the pressure drop of the medium in the two channels must be reduced in this embodiment. And, the sum of the lengths of the two channels in the present embodiment is greater than or equal to the length of the channel from the first manifold 210 directly to the second manifold 220. That is, the overall flow length of the medium within the core assembly 100 is not shortened, and as such, the heat exchange effect of the heat exchanger is not reduced.

In summary, the heat exchanger provided by the application has the advantages that the pressure drop of the medium is obviously reduced, and the heat dissipation effect is not reduced.

It should be noted that, in another embodiment, one of the first collecting port 210 or the second collecting port 220 may be used as the liquid inlet, and the other one and the middle collecting port 230 may be used as the liquid outlet. Taking the first collecting port 210 as an example, the pressure drop of the medium from the first collecting port 210 to the second collecting port 220 is larger, but the pressure drop of the medium from the first collecting port 210 to the middle collecting port 230 is significantly reduced, so that the purpose of reducing the pressure drop of part of the medium can be achieved.

In one embodiment, as shown in FIGS. 1-4, the first manifold 210, the intermediate manifold 230, and the second manifold 220 are collinear.

Thus, the heat exchanger is in a strip shape, which is beneficial to reducing the processing difficulty of the core plate assembly 100.

But is not limited thereto, in other embodiments, the first manifold 210, the intermediate manifold 230, and the second manifold 220 may also be located on different lines. For example, the straight line from the first collecting port 210 to the middle collecting port 230 is disposed at an angle to the straight line from the second collecting port 220 to the middle collecting port 230.

Or when the number of the intermediate collecting ports 230 is plural, for example, when the number of the intermediate collecting ports 230 is two, the first collecting port 210, the second collecting port 220, and the two intermediate collecting ports 230 may be distributed in four corners. Other distribution methods are not exemplified herein.

In one embodiment, as shown in fig. 1, 2, and 4, the distance from the first manifold 210 to the intermediate manifold 230 is equal to the distance from the second manifold 220 to the intermediate manifold 230. That is, the middle manifold 230 is just in the middle most position.

In other embodiments, as shown in FIG. 3, the distance from the first manifold 210 to the intermediate manifold 230 may not be equal to the distance from the second manifold 220 to the intermediate manifold 230. In this way, the length of the different media channels can be adjusted according to the actual situation (flow resistance, pressure drop or flow time).

Since there are multiple channels of medium in the heat exchanger, in the present application, when the channels of the multiple media are communicated with each other, the core plate assembly 100 may be shared between the channels of the multiple media, and when the channels of the respective media are not communicated with each other, the core plate assembly 100 having a smaller length may be used, for example, the number of channels from the intermediate collecting port 230 to the first collecting port 210 is greater than the number of channels from the intermediate collecting port 230 to the second collecting port 220, then for the more than one portion, the core plate assembly 100 may be separately disposed between the intermediate collecting port 230 to the first collecting port 210, and the core plate assembly 100 may extend only from the first collecting port 210 to the intermediate collecting port 230, but not to the second collecting port 220. Therefore, the material of the core plate assembly 100 is saved, the volume of the heat exchanger is reduced, and the number of the core plate assemblies 100 of the heat exchanger can be flexibly set according to actual needs, so that the heat exchanger is beneficial to improving the installation convenience of the heat exchanger.

Specifically, in one embodiment, as shown in fig. 4, the core plate assembly 100 includes a first plate set 130 and a second plate set 140, the first plate set 130 is in communication with the first manifold 210, the intermediate manifold 230, and the second manifold 220 in sequence, the second plate set 140 is in communication with the first manifold 210 and the intermediate manifold 230, and the second plate set 140 has a length less than the length of the first plate set 130.

In another embodiment, the core plate assembly 100 includes a third plate set and a fourth plate set, the third plate set is in communication with the first manifold 210, the intermediate manifold 230, and the second manifold 220 in sequence, the fourth plate set is in communication with the second manifold 220 and the intermediate manifold 230, and the length of the fourth plate set is less than the length of the third plate set.

In yet another embodiment, the core plate assembly 100 includes a fifth plate set that communicates with the first manifold 210 and the intermediate manifold 230 and a sixth plate set that communicates with the second manifold 220 and the intermediate manifold 230.

However, when the number of the intermediate fluid collecting ports 230 is plural, the core plate assembly 100 may be provided in more ways, which are not illustrated herein.

In one embodiment, the core plate assembly 100 includes a first core plate 110, a second core plate 120, and fins (not shown), the first core plate 110 and the second core plate 120 being sealingly connected, and the fins being disposed between the first core plate 110 and the second core plate 120.

Specifically, the first core plate 110 and the second core plate 120 may be welded, or may be connected by other manners, such as crimping, clamping, or even bonding. The fins can be H-shaped, Z-shaped or even combined, and can be arranged according to actual needs.

Further, in order to enhance the heat exchange effect between the core plate assemblies 100, in an embodiment, as shown in fig. 1 to 4, the first core plate 110 and the second core plate 120 are each provided with a protrusion 430, and the protrusions 430 are in a press-formed structure. And, the protrusion 430 of the first core plate 110 and the protrusion 430 of the second core plate 120 of the adjacent core plate assembly 100 abut each other.

It will be appreciated that the first and second headers 210, 220 and the intermediate headers 230 extend directly through the core plate assemblies 100, but the connection tightness is difficult to ensure if the adjacent core plate assemblies 100 are welded directly, and in particular, it is difficult to ensure that the medium at the first and second headers 210, 220 and the intermediate headers 230 does not penetrate between the adjacent core plate assemblies 100.

Thus, to improve the tightness of the heat exchanger, in one embodiment, as shown in fig. 2, the heat exchanger further includes sealing spacers disposed at the first and second headers 210, 220 and the middle headers 230 for connecting the adjacent core plate assemblies 100 and sealing the first and second headers 210, 220 and the middle headers 230.

Specifically, the sealing spacer includes a first spacer 310, a second spacer 320, and an intermediate spacer 330, the first spacer 310 is disposed at the first collecting port 210 and is respectively connected to the adjacent core plate assemblies 100, the second spacer 320 is disposed at the second collecting port 220 and is respectively connected to the adjacent core plate assemblies 100, and the intermediate spacer 330 is disposed at the intermediate collecting port 230 and is respectively connected to the adjacent core plate assemblies 100.

In this manner, the difficulty of sealing connection between adjacent core assemblies 100 is reduced. And, by providing the intermediate spacer ring 330 such that support points are increased between adjacent core plate assemblies 100, the true understanding amplitude of the heat exchanger can be effectively reduced, and the reliability of the heat exchanger can be improved.

Specifically, the first spacer ring 310, the second spacer ring 320, and the intermediate spacer ring 330 are welded to the adjacent core plate assemblies 100, respectively.

The application also provides a cooling system comprising the heat exchanger according to any one of the embodiments above. The heat exchanger may be an oil cooler, or may be another heat exchanger, and is not limited to this.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of the application should be determined from the following claims.
