Referring to fig. 1, the heat exchange device according to an embodiment of the present invention includes a water tank 101, a hydraulic module 102, and a second heat exchanger 103, where the water tank 101 includes a box housing 104 and an inner container 105, and the box housing 104 is provided with a mounting seat 106; the hydraulic module 102 is mounted on the mounting seat 106, and the hydraulic module 102 is provided with a refrigerant liquid pipe interface 107 and a refrigerant gas pipe interface 108; the second heat exchanger 103 is disposed in the casing 104 and is configured to exchange heat with the inner container 105, and two ends of the second heat exchanger 103 are respectively connected to the refrigerant liquid pipe interface 107 and the refrigerant gas pipe interface 108. In the existing system, the hydraulic module 102 is installed in a wall-mounted manner, and the water tank 101 is installed in a floor-mounted manner, i.e., the water tank needs to be installed in two different places, so that the installation cost is high, and the cost of two sets of equipment is also high. In the heat exchange device, the hydraulic module 102 is used for a heating system, the water tank 101 is used for a domestic hot water system, the mounting seat 106 is arranged on the water tank 101, and the hydraulic module 102 is mounted on the mounting seat 106, so that the structural layout of the upper heating lower water tank 101 is realized, the installation is stable, the occupied area is small, the heating system and the domestic hot water system share one air conditioner outdoor unit, the equipment cost is low, and the installation is simple.
In some embodiments, to prevent water from dripping from the hydro modules 102 onto the floor, the mounting block 106 is provided with a water trap that collects water dripping from the hydro modules 102, keeping the floor clean. To facilitate draining of collected water, in some embodiments, a drain opening 109 is provided in the mounting block 106.
In some embodiments, the hydraulic module 102 is further provided with a first heat exchanger 110, an electric heating tank 111, a water pump 112, a first water inlet 113 and a first water outlet 114, the refrigerant liquid pipe connector 107 and the refrigerant gas pipe connector 108 are used for connecting a refrigerant of an outdoor unit of an air conditioner, the first heat exchanger 110 is provided with a first heat exchange flow path 115 and a second heat exchange flow path 116, the first heat exchange flow path 115 is respectively connected with the refrigerant liquid pipe connector 107 and the refrigerant gas pipe connector 108, the second heat exchange flow path 116 is respectively connected with the electric heating tank 111 and the water pump 112, the water pump 112 is connected with the first water inlet 113, and the electric heating tank 111 is connected with the first water outlet 114; the first heat exchange flow path 115 is a refrigerant flow path, the second heat exchange flow path 116 is a water flow path, and water in the water flow path exchanges heat with refrigerant in the refrigerant flow path. The heating backwater passes through the first water inlet 113, flows through the water pump 112, enters the first heat exchanger 110 for heating, flows through the electric heating tank 111, and is supplied to the heating system through the first water outlet 114. When the temperature of the water flowing out of the first heat exchanger 110 does not meet the requirement, the electric heating tank 111 can be used for heating the water, so that the temperature of the water flowing out of the electric heating tank 111 is ensured to be enough to meet the requirement of the water temperature when the hydraulic module 102 is applied.
In some embodiments, an expansion tank 117 is connected between the second heat exchange flow path 116 and the electrical heating tank 111. The expansion tank 117 is connected to the waterway system through a joint for buffering pressure fluctuation of the waterway system. Because the second heat exchange flow path 116 is a water flow path, the expansion with heat and contraction with cold characteristics of water are obvious, in the heat exchange process, the pressure of the water path system can change along with the change of the water temperature, when the pressure of the water path system is too high, water can enter the expansion tank 117 through the joint so as to reduce the pressure of the water path system, and each part of the water path system is protected from being damaged due to the too high pressure. In some embodiments, a pressure relief valve is further connected between the second heat exchange flow path 116 and the electric heating tank 111 to further protect various parts of the water path system from being damaged due to over-high pressure.
In some embodiments, a water flow switch 118 and a water pressure gauge 119 are also connected between the water pump 112 and the first water inlet 113 to enhance control of the waterway system.

It should be noted that the first throttling element 120 and the second throttling element 121 may be one of an electronic expansion valve, a thermostatic expansion valve, and a capillary tube, or may be any combination of two of the electronic expansion valve, the thermostatic expansion valve, and the capillary tube, or may be a combination of the electronic expansion valve, the thermostatic expansion valve, and the capillary tube.
In some embodiments, in order to filter impurities in the refrigerant flowing into the first throttling element 120 and the second throttling element 121 to prevent the first throttling element 120 and the second throttling element 121 from being blocked, filters 122 are connected to both ends of the first throttling element 120 and the second throttling element 121. It will be appreciated that in some embodiments, the filter 122 may be attached to only one end of the first throttling element 120 and the second throttling element 121.
In some embodiments, an electrical heating device 123 is disposed in the water tank 101.
