Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling heat exchangers, and particularly relates to a high-efficiency liquid cooling heat exchanger with a finned heat exchange structure in a channel. Background Art

[0002] The battery liquid cooling plate is a component that directly exchanges heat with the battery in the battery thermal management system. The liquid cooling plate is a product element of a liquid cooling radiator. Its heat dissipation principle is to set a coolant flow channel (heat exchange channel) in a metal plate. Electronic components are installed on the surface of the water cooling plate. The coolant enters from the inlet of the flow channel and then exits from the outlet. The coolant circulates between the cooler and the flow channel to absorb heat and cool down the metal plate, thereby cooling the electronic components at its outer end.

[0003] However, in the existing liquid cooling radiator, the inner wall of the coolant flow channel (heat exchange channel) provided inside is relatively smooth, the contact area between the coolant and the inner wall of the flow channel is small, and the heat exchange area between the two is small. Moreover, the coolant circulates rapidly in the flow channel, and its contact time with the inner wall of the flow channel is also short, which will affect the heat absorption effect of the coolant.

[0004] In order to solve this technical problem, the utility model proposes a high-efficiency liquid cooling heat exchanger with a finned heat exchange structure in a channel. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a high-efficiency liquid cooling heat exchanger with a finned heat exchange structure in a channel, which can effectively solve the problems mentioned in the background art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A high-efficiency liquid cooling heat exchanger with a finned heat exchange structure in a channel includes a mounting plate. A liquid inlet pipe is connected to the side end of the mounting plate. A first heat exchange pipe is arranged inside the mounting plate. A second heat exchange pipe is arranged inside the mounting plate. Raised corrugations are arranged inside both the first heat exchange pipe and the second heat exchange pipe. A U-shaped connecting pipe is connected between the first heat exchange pipe and the second heat exchange pipe. A liquid outlet pipe is connected to the side end of the mounting plate.

[0008] Preferably, the mounting plate is an aluminum substrate, and the liquid inlet pipe, the U-shaped connecting pipe, and the liquid outlet pipe are all aluminum pipes.

[0009] Preferably, one end of the first heat exchange pipe is communicated with the liquid inlet pipe, and the other end is communicated with the U-shaped connecting pipe. One end of the second heat exchange pipe is communicated with the liquid outlet pipe, and the other end is communicated with the U-shaped connecting pipe.

[0010] Preferably, a plurality of mounting holes are opened inside the mounting plate, and bolt rods are rotatably connected inside the mounting holes.

[0011] Preferably, communicating pipes are connected to the side ends of the liquid inlet pipe and the liquid outlet pipe. The communicating pipes are copper pipes, and rubber sleeves are arranged at the outer ends of the joints of the liquid inlet pipe, the liquid outlet pipe and the communicating pipes.

[0012] Preferably, a connector is arranged at the side end of the connecting pipe. The connector at the side end of the liquid inlet pipe is connected to the outlet of the cooler, and the connector at the side end of the liquid outlet pipe is connected to the inlet of the cooler.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, a first heat exchange pipe and a second heat exchange pipe are arranged in the mounting plate. When the coolant enters the first heat exchange pipe and the second heat exchange pipe, the coolant contacts the inner wall of the heat exchange pipe, and it will be able to absorb the heat in the mounting plate, thereby absorbing heat and cooling the electronic components connected to the side end of the mounting plate. Since convex corrugations are arranged in the first heat exchange pipe and the second heat exchange pipe, it can not only increase the contact area between the coolant and the inner wall of the heat exchange pipe and increase the heat exchange area in the channel, but also the convex corrugations can slow down the flow rate of the coolant, enabling it to have sufficient time to contact the inner wall of the heat exchange pipe, so as to improve the cooling efficiency of the device.

[0015] In the utility model, communicating pipes are arranged. The communicating pipes are copper pipes, which are convenient for connecting with external copper pipes. By arranging connectors, the liquid inlet pipe and the liquid outlet pipe can be connected to an external cooler, so that the coolant can circulate between the device and the cooler, and thus the device can continuously absorb heat and cool down.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-3 shown, a high-efficiency liquid-cooled heat exchanger with a finned heat exchange structure in the channel includes a mounting plate 1. The mounting plate 1 is an aluminum substrate with good thermal conductivity, which can conveniently conduct heat, thereby facilitating the absorption of heat generated by the electronic components connected to its outer end. A plurality of mounting holes 8 are formed in the mounting plate 1, and a bolt rod 9 is rotatably connected in the mounting hole 8. The bolt rod 9 cannot be separated from the mounting hole 8, so as to prevent the loss of the bolt rod 9 and also facilitate the installation and disassembly of the electronic components.

[0022] A liquid inlet pipe 2 is connected to the side end of the mounting plate 1. A first heat exchange pipe 3 and a second heat exchange pipe 4 are arranged in the mounting plate 1. When the coolant enters the first heat exchange pipe 3 and the second heat exchange pipe 4, it will be able to contact the inner walls thereof, thereby absorbing the heat of the mounting plate 1, and then absorbing heat and cooling the electronic components at its outer end through the mounting plate 1. Convex corrugations 5 are arranged in both the first heat exchange pipe 3 and the second heat exchange pipe 4. The convex corrugations 5 are used to increase the contact area between the coolant and the inner walls of the first heat exchange pipe 3 and the second heat exchange pipe 4, so as to increase the heat exchange area in the channel and thus improve the cooling efficiency of the device.

[0023] A U-shaped connecting pipe 6 is connected between the first heat exchange pipe 3 and the second heat exchange pipe 4. One end of the first heat exchange pipe 3 is communicated with the liquid inlet pipe 2, and the other end is communicated with the U-shaped connecting pipe 6. One end of the second heat exchange pipe 4 is communicated with the liquid outlet pipe 7, and the other end is communicated with the U-shaped connecting pipe 6. In this way, the coolant will enter the U-shaped connecting pipe 6 from the first heat exchange pipe 3 and then enter the second heat exchange pipe 4. A liquid outlet pipe 7 is connected to the side end of the mounting plate 1, and the coolant finally discharges from the liquid outlet pipe 7. Liquid connecting pipes 10 are connected to the side ends of both the liquid inlet pipe 2 and the liquid outlet pipe 7. The connecting pipes 10 are copper pipes, which can facilitate the connection with external copper pipes. Rubber sleeves are arranged at the outer ends of the joints of the liquid inlet pipe 2, the liquid outlet pipe 7 and the connecting pipes 10. The rubber sleeves are used to seal the joints to prevent liquid leakage. A connecting head 11 is arranged at the side end of the connecting pipe 10. The connecting head 11 at the side end of the liquid inlet pipe 2 is connected to the outlet of the cooler, and the connecting head 11 at the side end of the liquid outlet pipe 7 is connected to the inlet of the cooler. In this way, the coolant can circulate between the device and the cooler, so that the device can continuously absorb heat and cool down.
