The terms "mounted," "one end," "the other end," and the like as used herein are for illustrative purposes only.

As shown in fig. 1-3, the embodiment of the present invention provides a heat exchanger with embedded spoiler, including a tank body 1, the tank body 1 is a sealed container, its inner space is used as a heat exchange cavity 11, a heat exchange tube 2 is provided in the tank body 1, and the tank body 1 is provided with a first medium inlet 21, a first medium outlet 22, a second medium inlet 12 and a second medium outlet 13. The first medium inlet 21 and the first medium outlet 22 are respectively connected with two ends of the heat exchange tube 2, two ends of the heat exchange tube 2 extend out of the tank body 1, the second medium inlet 12 and the second medium outlet 13 are communicated with the heat exchange cavity 11 in the tank body 1, the heat exchange tube 2 is spirally coiled into a heat exchange barrel 23, a spoiler 3 is further clamped between spiral gaps of the heat exchange tube 2, the spoiler 3 is also spirally arranged, and the spiral direction of the spoiler is consistent with the spiral direction of the heat exchange tube 2. In this embodiment, the first medium inlet 21 is located at the bottom of the tank 1, the first medium outlet 22 is located at the top of the tank, and when a second medium, such as a refrigerant, enters the heat exchange cavity 11 in the tank 1, the second medium flows toward the bottom of the tank 1 along the spiral spoiler 3 under the action of gravity, instead of directly falling on the bottom of the tank 1, so that the fluidity of the second medium in the tank 1 is increased, and therefore, heat exchange can be performed more sufficiently between the second medium passing through the tank 1 and the first medium passing through the heat exchange tube 2, that is, the heat exchange efficiency of the heat exchanger is improved.

As shown in fig. 2, in the preferred embodiment, the spoiler 3 is further provided with a plurality of protrusions 31 and/or recesses 32, respectively, the protrusions 31 and the recesses 32 are integrally formed on the spoiler 3 by stamping, the protrusions 31 and the recesses 32 are arranged along the length direction of the spoiler 3, and the protrusions 31 and the recesses 32 are sequentially arranged alternately and at intervals. The spoiler 3 in this embodiment is an aluminum alloy spoiler, which is light in weight and easy to machine, although other spoilers 3, such as a pure copper spoiler, may be used. When the second medium flows along the spoiler 3, the protrusion 31 and the recess 32 may form a barrier or interference to the flow of the second medium, so that the second medium generates turbulent motion (turbulence or turbulent flow) when flowing, and the heat in the second medium is more sufficiently transferred to the first medium in the heat exchange tube 2 through the heat exchange tube, thereby further improving the heat exchange efficiency of the heat exchanger.

In the preferred embodiment, as shown in fig. 2, the heat exchange tube 2 is sleeved with fins 24, the fins 24 are arranged along the length direction of the heat exchange tube 2, and the fins 24 and the heat exchange tube 2 are fixed by welding.
