[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] like Figure 1The heat exchange assembly shown includes: a heat exchange body 1, which can exchange heat with the refrigerant entering it, a water inlet cavity 2, the water inlet cavity 2 is connected to the heat exchange body 1, and a cooling inlet is provided on the water inlet cavity 2, a fluid driving component 3 is arranged in the water inlet cavity 2, the fluid driving component 3 pumps cooling water into the water inlet cavity 2 from the cooling inlet, and generates pressure inside the water inlet cavity 2 to make the cooling water flow into the heat exchange body 1 and exchange heat with the refrigerant inside the heat exchange body 1; a driving mechanism 5, the driving mechanism 5 is arranged on the outer surface of the water inlet cavity 2, and the output shaft of the driving mechanism 5 passes through the water inlet cavity 2 and is transmission-connected with the fluid driving component 3, wherein the driving force of the fluid driving component 3 is provided by the driving mechanism 5 outside the water inlet cavity 2, thereby realizing the normal operation of the fluid driving component 3 while avoiding the entire water pump being arranged inside the water inlet cavity 2 to affect the amount of cooling water entering the heat exchange body 1, and also overcoming the problem of needing additional waterproof protection for the electronic components of the water pump.

[0031] A first partition 4 is arranged in the water inlet cavity 2, and the first partition 4 divides the water inlet cavity 2 into a water inlet area 21 and a pressurizing area 22 which are interconnected. The fluid driving component 3 is arranged in the pressurizing area 22, and the cooling inlet is arranged on the water inlet area 21. The first partition 4 is used to separate the inlet and outlet of the fluid driving component 3, and together with the inner surface of the water inlet cavity 2, a structure similar to a water pump casing is formed for the fluid driving component 3, thereby increasing the driving efficiency of the fluid driving component 3.

[0032] The first partition plate 4 is provided with a circulation hole 44, and the water inlet area 21 and the pressurized area 22 are connected through the circulation hole 44. The fluid driving component 3 is correspondingly arranged at the position of the circulation hole 44, so that the water inlet area 21 and the pressurized area 22 can only be connected through the fluid driving component 3, that is, the pressurized area 22 and the fluid driving component 3 together constitute a water pump structure, and the circulation hole 44 is the water inlet of the water pump structure. The cooling water is pumped into the pressurized area 22 by the fluid driving component 3 and then flows to the inside of the heat exchange body 1 for heat exchange.

[0033] The cross-sectional shape of the first baffle 4 is a curve, and both ends of the curve are sealed with the inner surface of the water inlet cavity 2, wherein the specific shape of the curve can be determined according to the structure of the water inlet cavity 2, such as an arc or a broken line, etc.; or the cross-sectional shape of the first baffle 4 is a long strip, and both ends of the long strip are sealed with the inner surface of the water inlet cavity 2. Preferably, the long strip has an angle α with the fluid flow direction at the cooling inlet, and 0°<α<180°, that is, the first baffle 4 is a flat plate structure, and the first baffle 4 is inclined, thereby facilitating the sealing of the edge of the first baffle 4 with the water inlet cavity 2.

[0034] The first partition 4 includes a first section 41, a second section 42 and a third section 43 which are connected in sequence. The first end of the first section 41 is sealed to the inner surface of the water inlet cavity 2, the second end of the third section 43 is sealed to the inner surface of the water inlet cavity 2, and the flow hole 44 is arranged on the second section 42. The second end of the first section 41 is connected to the first end of the second section 42, and the second end of the second section 42 is connected to the first end of the third section 43. The first partition 4 is arranged in a Z shape so that the volume of the water inlet area 21 and the pressurized area 22 are not much different, and the length of the second section 42 is used to form the working area of ​​the fluid drive component 3, which is convenient for arranging the fluid drive component 3.

[0035] The fluid driving component 3 includes an impeller, which is disposed in the pressurized area 22 . When the impeller rotates, negative pressure is generated at the flow hole 44 , thereby pumping water from the water inlet area 21 into the pressurized area 22 through the flow hole 44 .

[0036] The impeller forms a circular tube shape when rotating, and the circular tube shape has a first end face and a second end face opposite to each other. The first end face is formed with a fluid inlet of the impeller, and the side wall of the circular tube shape is formed with a fluid outlet of the impeller, that is, the impeller has a structure of axial liquid inlet and radial liquid outlet, and the flow hole 44 is located on the side of the first end face away from the second end face, so that the impeller can directly absorb liquid from the flow hole 44.

[0037] There is a gap between the first end face and the second section 42 to avoid interference between the impeller and the second section 42, but the gap needs to be as small as possible to avoid a large amount of fluid entering and exiting the pressurized area 22 through the gap and causing the effect of the fluid drive component 3 to be reduced.

[0038] The rotation axis of the impeller is colinear with the axis of the flow hole 44 , thereby maximizing the driving effect of the fluid driving component 3 .

[0039] The heat exchange component also includes a seal 6. A mounting hole 23 is provided on the side wall of the water inlet cavity 2. The seal 6 is arranged at the mounting hole 23, and the output shaft passes through the seal 6 and extends into the water inlet cavity 2. The mounting hole 23 is used to increase the convenience of placing the fluid driving component 3 into the water inlet cavity 2 for installation. At the same time, the seal 6 is used to seal the mounting hole 23 to ensure the reliability of the heat exchange component.

[0040] A bracket is arranged on the sealing member 6 , and the driving mechanism 5 is arranged on the bracket and the sealing member 6 .

[0041] The size of the sealing member 6 is slightly larger than the size of the mounting hole 23 , so that the sealing member 6 can be sealed with the outer surface of the water inlet cavity 2 around the mounting hole 23 .

[0042] The sealing member 6 is recessed into the water inlet cavity 2 to form a receiving area, and the driving mechanism 5 is arranged in the receiving area, that is, while minimizing the length of the output shaft, the protruding height of the driving mechanism 5 is reduced, thereby minimizing the space occupied by the heat exchange component.

[0043] When the heat exchange component is filled with water, the gas in the heat exchange component flows into the water inlet cavity 2 and forms high-pressure air in the water inlet cavity 2. When there is high-pressure air in the water inlet cavity 2, the fluid driving mechanism cannot pump cooling water into the water inlet cavity. Therefore, an emptying mechanism is provided on the water inlet cavity 2, and the gas in the water inlet cavity 2 is discharged by the emptying mechanism, thereby avoiding the problem that the cooling water cannot be pumped in due to the presence of high-pressure air in the water inlet cavity 2. Preferably, the emptying mechanism is provided on the water inlet area 21 to ensure that there is fluid at the inlet of the fluid driving component 3.

[0044] The heat exchange body 1 is provided with a heat exchange tube, and the water inlet end of the heat exchange tube is connected to the pressurized area 22, so as to ensure that the cooling water entering the heat exchange tube has a certain pressure and ensure the normal flow of the cooling water.

[0045] The heat exchange assembly also includes a water chamber shell 8, the water inlet cavity 2 is formed inside the water chamber shell 8, the heat exchange body 1 has a heat exchange shell, and the water inlet cavity 2 shell is fixedly arranged on the first end of the heat exchange shell, that is, the water chamber shell 8 is additionally fixedly arranged at the first end on the basis of not changing the existing heat exchanger, which only increases the length of the heat exchanger without causing the problem of large occupied space caused by the separate arrangement of the water pump in the prior art. Preferably, the material of the water chamber shell 8 includes seamless steel pipe or carbon steel, and the cross-sectional shape of the water chamber shell 8 is the same as the cross-sectional shape of the heat exchange shell.

[0046] When the heat exchange body 1 is provided with a water inlet and a water outlet at the first end, a second partition plate 7 is provided in the water chamber shell 8, and the second partition plate 7 divides the interior of the water chamber shell 8 into the water inlet cavity 2 and the water outlet, and the water outlets of all heat exchange tubes are connected to the water outlet, thereby ensuring the reliability of the heat exchange component.

[0047] The heat exchange assembly also includes a tube sheet and a heat exchange shell. The tube sheet is arranged inside the heat exchange shell, and the inside of the heat exchange shell is divided into a water storage part and the heat exchange body 1. The water storage part constitutes the water inlet cavity 2, that is, the end of the heat exchanger that plays a water-dividing role in the prior art is used to form the water inlet cavity 2, or an additional tube sheet is added to the heat exchanger in the prior art to form the water storage part, so that the fluid driving component 3 and the driving mechanism 5 are both arranged on the heat exchanger without changing the size of the heat exchanger, thereby minimizing the occupied space of the heat exchange assembly.

[0048] When the heat exchange body 1 is provided with a water inlet and a water outlet at the first end, a second partition 7 is provided in the water storage part, and the second partition 7 divides the water storage part into a water inlet cavity 2 and a water outlet part. The water outlets of all heat exchange tubes are connected to the water outlet part, thereby ensuring the reliability of the heat exchange component.

[0049] The heat exchange component also includes a detection mechanism, which is electrically connected to the fluid driving component 3. The detection mechanism can detect the inlet and outlet water temperatures and outlet water flow of the heat exchange component. When the unit is running, the detection mechanism can automatically adjust the working state (such as the rotation speed, etc.) of the fluid driving component 3 according to the obtained inlet and outlet water temperatures and the user's heat load, thereby adjusting the flow of cooling water entering the heat exchange body 1. At the same time, the detection mechanism can also determine whether the water flow in the heat exchange component meets the working requirements of the fluid driving component 3 based on the outlet water flow. If the water flow cannot meet the working requirements, the heat exchange component is controlled to stop working.

[0050] The heat exchange component is provided with a drain valve, and after the heat exchange component stops working, the drain valve is used to drain the cooling water in the heat exchange component to avoid freezing of the heat exchange component.

[0051] An air conditioning system comprises the above-mentioned heat exchange component.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
