[0010] The present invention will be described in detail below with reference to the embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional modifications made by those skilled in the art based on these embodiments are within the scope of protection of the present invention.

[0011] In each of the figures of the present invention, the dimensions of some of the structures or parts are exaggerated relative to other structures or parts for ease of illustration, and are therefore only intended to illustrate the basic structure of the subject matter of the present invention.

[0012] For ease of explanation, the upper and lower are defined based on the positions of the fluid control module of the present invention in an actual use state. In this specification, "connection" refers to a direct connection or an indirect connection via another quick joint / adapter, and "direct connection" refers to a connection in which no other structure or quick joint exists between two parts.

[0013] 1 to 6, the fluid control module of the present invention includes an inlet port 2, a circulation pump 1, a heat exchanger 3, an outlet port 4, and a quick joint that connects two adjacent components. The heat exchanger 3 is connected between the circulation pump 1 and the outlet port 4, or the heat exchanger 3 is connected between the inlet port 2 and the circulation pump 1.

[0014] The inlet port 2 and the outlet port 4 are used to connect with a heat dissipation component, and the primary fluid circulates between the heat dissipation component and the fluid control module by driving the circulation pump 1. When the primary fluid flows through the heat exchanger 3 and there is a temperature difference between the primary fluid and the secondary fluid flowing through the heat exchanger 3, heat exchange occurs between the primary fluid and the secondary fluid, the primary fluid acquires energy and rises to a desired temperature, and then flows through the heat dissipation component to release heat to the outside, thus fulfilling the heating function. Of course, the inlet port 2 and the outlet port 4 can also be connected to a cooling component, and heat exchange occurs between the primary fluid and the secondary fluid, the primary fluid drops to a desired temperature, and then flows through the cooling component to release cold to the outside, thus fulfilling the cooling function.

[0015] Moreover, the primary fluid is preferably water, which has a high specific heat, is low cost, and is environmentally friendly.

[0016] Of course, the primary fluid can also be selected as oil or other liquid, especially under special temperature requirements, for example, when the working temperature of the primary fluid is below 0°C or above 100°C, oil or other liquid can be selected. Other liquids include, but are not limited to, alcohol-water mixture, salt water, and organic refrigerant.

[0017] Preferably, the inlet port 2 and the outlet port 4 are located on the same side to facilitate quick disconnect connection with the heat dissipating or cooling component.

[0018] The heat exchanger 3 includes a primary fluid heat exchange inlet 31, a primary fluid heat exchange outlet 32, and a primary fluid flow path connecting the primary fluid heat exchange inlet and the primary fluid heat exchange outlet. The heat exchanger 3 used in the present invention is a compact type heat exchanger 3, which has a small volume and a small thermal resistance. Its structure can be referred to CN102706189A, CN202599167U, and will not be described in detail here.

[0019] An appropriate output is selected for the circulation pump 1 based on factors such as the magnitude of pressure of the heat dissipation or cooling components, the head, etc. Specifically, a fixed frame 13 is disposed below the circulation pump 1, and a plurality of rubber support legs 131 are disposed on the bottom of the fixed frame 13. The fixed frame 13 makes it easy to mount and fix the circulation pump 1, and the rubber support legs 131 perform a certain vibration-proofing and cushioning function, reducing noise / vibration during operation of circulation pumps such as water pumps and oil pumps, making the operating state more stable, and preventing resonance.

[0020] The fluid control module of the present invention employs a direct connection method that does not use piping, and each component is connected with a quick joint, which results in a short connection path between the components and high reliability. The overall structure of the assembled fluid control module is small, requiring significantly less installation space, lightweight, easy to transport, and easy to connect to other components.

All "connections" in this example are "direct connections".

[0034] Further, the fluid control module includes a first temperature detection unit 311 attached to the primary fluid heat exchange inlet 31 side and / or a second temperature detection unit 312 attached to the primary fluid heat exchange outlet 32 ​​side, and the first temperature detection unit 311 and the second temperature detection unit 312 are both communicably connected to a control device. The first temperature detection unit 311 detects the temperature of the primary fluid entering the heat exchanger 3 in real time, and the second temperature detection unit 312 detects the temperature of the primary fluid after it flows out of the heat exchanger 3 in real time. An operator can check the corresponding value through the control device, and when the temperature difference detected by the first temperature detection unit 311 and the second temperature detection unit 312 is lower than a set value, the control device can issue a remote alarm to remind the operator to check the operating state of the heat exchanger 3 in a timely manner.

[0035] Specifically, the first temperature detection unit 311 includes a first temperature sensor 3112 and a first mounting structure 3111 for mounting the first temperature sensor 3112. The first mounting structure 3111 mounts the first temperature sensor 3112 to any quick joint between the primary side fluid heat exchange inlet 31 and the inlet port 2.

[0036] In a preferred embodiment, the first mounting structure 3111 mounts the first temperature sensor 3112 to a quick joint directly connected to the primary fluid heat exchange inlet 31, and the measured temperature is the temperature of the primary fluid immediately before it enters the heat exchanger 3, and the influence of other components on the temperature when the primary fluid passes through them is eliminated. For example, in the case of the above-mentioned Example 1, Example 2, and Example 3 shown in Figs. 1 to 5, the first temperature sensor 3112 can be mounted to the second quick joint 33 by the first mounting structure 3111. Or, in the case of the example of Figs. 4 to 7, the first temperature sensor 3112 can be mounted to the first quick joint 21 by the first mounting structure 3111.

[0037] The shape and mounting method of the first mounting structure 3111 are not limited as long as the first temperature sensor 3112 can be mounted and fixed and the temperature measurement of the primary fluid is not affected. In one embodiment, as shown in Figs. 1 to 5, the first mounting structure 3111 is a first mounting bracket, which is fixed to a quick joint by a screw, the first temperature sensor 3112 is attached to the first mounting bracket, and the temperature measuring part of the first temperature sensor 3112 is inserted into the quick joint to which it is attached, to detect the temperature of the primary fluid. In another embodiment, the first mounting structure 3111 may be a thermally conductive tape or the like, and the first temperature sensor 3112 is attached to the quick joint to detect the temperature of the primary fluid.

[0038] The second temperature detection unit 312 includes a second temperature sensor 3122 and a second mounting structure 3121 for mounting the second temperature sensor 3122, and the second mounting structure 3121 enables the second temperature sensor 3122 to be mounted to any quick joint between the primary side fluid heat exchange outlet 32 ​​and the outlet port 4.

[0039] In the cases based on Example 1, Example 2 and Example 3, the second temperature sensor 3122 can be attached to the third quick joint 41 by the second mounting structure 3121, and the temperature of the primary side fluid at the outlet of the heat exchanger 3 can be obtained to directly reflect the heat exchange efficiency of the heat exchanger 3. In the cases based on Example 2 and Example 3, the second temperature sensor 3122 can also be attached to the second three-way joint 6 by the second mounting structure 3121. In the case based on Example 3, the second temperature sensor 3122 can also be attached to the fourth quick joint 42 by the second mounting structure 3121.

[0040] In the case based on Examples 4 to 7, the second temperature sensor 3122 can be attached to the third quick joint 41 by the second mounting structure 3121, in the case based on Examples 5 to 7, the second temperature sensor 3122 can be attached to the fourth quick joint 42 by the second mounting structure 3121, in the case based on Examples 6 to 7, the second temperature sensor 3122 can be attached to the second three-way quick joint by the second mounting structure 3121, and in the case based on Example 7, the second temperature sensor 3122 can be attached to the third three-way quick joint by the second mounting structure 3121.

[0041] The shape and mounting method of the second mounting structure 3121 are not limited as long as it can mount and fix the second temperature sensor 3122 and does not affect the temperature measurement of the primary fluid. In one embodiment, as shown in Figs. 1 to 5, the second mounting structure 3121 is a second mounting bracket, which is fixed to a quick joint by a screw, the second temperature sensor 3122 is attached to the second mounting bracket, and the temperature measuring part of the second temperature sensor 3122 is inserted into the quick joint to which it is attached, to detect the temperature of the primary fluid. In another embodiment, the second mounting structure 3121 may be a thermally conductive tape or the like, and the second temperature sensor 3122 is attached to the quick joint to detect the temperature of the primary fluid.

[0042] In addition, the fluid control module includes a bypass pipe 7 connecting the upstream side of the primary fluid heat exchange inlet 31 and the downstream side of the primary fluid heat exchange outlet 32. On the one hand, it can form a protection circuit to protect the system when the system is clogged. On the other hand, when the second temperature sensor 3122 detects that the temperature of the primary fluid after passing through the heat exchanger 3 does not reach the desired temperature value, the primary fluid will return to the primary fluid heat exchange inlet 31 side through the bypass pipe 7, and then perform secondary heat exchange in the heat exchanger 3 to ensure that the temperature of the primary fluid discharged from the outlet port 4 meets the requirement.

[0043] Preferably, one end of the bypass pipe 7 is connected to a side farther from the heat exchanger 3 than the first temperature detection unit 311 so that the returned primary fluid enters the heat exchanger 3 after being measured by the first temperature detection unit 311, and the other end of the bypass pipe 7 is connected to a side farther from the heat exchanger 3 than the second temperature detection unit 312 so that if a primary fluid with an inappropriate temperature is detected after measurement by the second temperature detection unit 312, the bypass pipe 7 is activated to return the primary fluid. If the temperature reaches a predetermined temperature, there is no need to return it.

[0044] Specifically, at least one quick joint between the primary side fluid heat exchange inlet 31 and the inlet port 2 is a three-way quick joint, at least one quick joint between the primary side fluid heat exchange outlet 32 ​​and the outlet port 4 is a three-way quick joint, and the bypass pipe 7 is connected to the two three-way quick joints.

[0045] In the case based on Example 1, the first quick joint 21 and the third quick joint 41 are both three-way quick joints, and the bypass pipe 7 is connected between the first quick joint 21 and the third quick joint 41. Or in the case based on Example 1, the first quick joint 21 and the third quick joint 41 are both three-way quick joints, the fluid control module further includes a first three-way joint 5 connected to the first quick joint 21, the bypass pipe 7 is connected between the first three-way joint 5 and the third quick joint 41, and the other connection port of the first three-way joint 5 is connected to a functional component. Or, in the case based on Example 2, the first quick joint 21 is a three-way quick joint, and the bypass pipe 7 is connected between the first quick joint 21 and the second three-way joint 6. Or, in the case based on Example 2, the first quick joint 21 is a three-way quick joint, the fluid control module further includes a first three-way joint 5 connected to the first quick joint 21, the bypass pipe 7 is connected between the first three-way joint 5 and the second three-way joint 6, and the other connection port of the first three-way joint 5 is connected to a functional component. Or, in the case based on Example 3, the first quick joint 21 is a three-way quick joint, and the bypass pipe 7 is connected between the first quick joint 21 and the second three-way joint 6. Or, in the case based on Example 3, the first quick joint 21 is a three-way quick joint, the fluid control module further includes a first three-way joint 5 connected to the first quick joint 21, the bypass pipe 7 is connected between the first three-way joint 5 and the second three-way joint 6, and the other connection port of the first three-way joint 5 is connected to a functional component.

[0046] In the case of the fourth embodiment, the first quick joint 21 and the third quick joint 41 are both three-way quick joints, and the bypass pipe 7 is connected between the first quick joint 21 and the third quick joint 41 .

[0047] In the case of Example 5, the first quick joint 21 is a three-way quick joint, one of the third quick joint 41 and the fourth quick joint 42 is a three-way quick joint, and the bypass pipe 7 is connected between the first quick joint 21 and one of the third quick joint 41 and the fourth quick joint 42.

[0048] In the case of the sixth embodiment, the first quick joint 21 is a three-way quick joint, and the bypass pipe 7 is connected between the first quick joint 21 and the second three-way quick joint.

[0049] In the case based on Example 7, the first quick joint 21 is a three-way quick joint, the bypass pipe 7 is connected between the first quick joint 21 and the second three-way quick joint, and the other connection port of the third three-way quick joint is connected to a functional component. Or, the bypass pipe 7 is connected between the first quick joint 21 and the third three-way quick joint, and the other connection port of the second three-way quick joint is connected to a functional component.

[0050] In the above embodiment, the functional component is the air bleed valve 211 or the relief valve 8.

[0051] Furthermore, the fluid control module includes an air bleed valve 211 and / or a relief valve 8 connected to the flow path of the fluid control module.

[0052] The relief valve 8 is used to release pressure in the system, prevent safety accidents caused by excessive pressure, and improve the explosion-proof performance of the fluid control module, and can be installed at any position of the fluid control module.

[0053] When gas is mixed into the fluid control module, the gas will move upward along the flow path and finally gather at the highest part of the flow path. Therefore, the air vent valve 211 can be connected to the highest point of the flow path. The gas enters the air vent valve 211 and gathers at the top of the valve cavity, and as the gas in the valve increases, the pressure increases. When the gas pressure is greater than the system pressure, the gas will cause the water level in the valve cavity to drop, and the float will drop with the water level to open the exhaust port. After the gas is discharged, the water level will rise and the float will also rise to close the exhaust port. The above structural design can discharge excess gas in the system and improve the safety of use of the fluid control module.

[0054] In the present invention, the heat exchanger 3 is located at the upper end of the circulating pump 1, and the primary fluid heat exchange inlet 31 and the primary fluid heat exchange outlet 32 ​​are vertically distributed on both sides of the heat exchanger 3, at least one quick joint is provided between the primary fluid heat exchange outlet 32 ​​and the outlet port 4 as necessary, and the at least one quick joint is located at approximately the same horizontal position, and any quick joint between the primary fluid heat exchange outlet 32 ​​and the outlet port 4 is located at the highest point of the system flow path, and the air bleed valve 211 can be installed on any of them.

[0055] In addition, when gas is present in the system, the gas will affect the heat exchange between the primary fluid and the secondary fluid when it enters the heat exchanger 3, so the air bleed valve 211 can also be connected to the primary fluid heat exchange inlet 31 side. At least one quick joint between the inlet port 2 and the primary fluid heat exchange inlet 31 is a three-way quick joint, and the air bleed valve 211 is connected to the three-way quick joint.

[0056] Preferably, the air vent valve 211 is connected to a connection port that opens upward of the three-way quick joint, which is advantageous for discharging gas.

A first temperature sensor 3112 is attached to the second quick joint 33, and a second temperature sensor 3122 is attached to the fourth quick joint 42, and both of these two quick joints are two-way quick joints, which facilitates modular customization and installation. A bypass pipe 7 connects the first three-way joint 5 and the second three-way joint 6. One of the air bleed valve 211 and the relief valve 8 is connected to the first three-way joint 5, and the other is connected to the third quick joint 41 directly or via a 90-degree quick joint.

[0060] Referring to Fig. 1, the 90-degree quick joint is installed in order to reduce the large impact on the overall volume after installation of the pressure valve, improve space utilization rate, and make the overall structure more compact by installing the pressure valve facing downwards and positioning the pressure valve close to the heat exchanger 3.

[0063] Furthermore, the fluid control module includes a casing 10, and the casing 10 is provided with a first opening 101 for protruding the inlet port 2 and a second opening 102 for protruding the outlet port 44. The installation of the casing 10 can provide good protection for each component in the fluid control module, and only the inlet port 2 and the outlet port 44 are exposed to the outside for workers to connect to corresponding heat dissipation or cooling components, facilitating transportation and improving the overall aesthetics.

[0064] Furthermore, the fluid control module includes a strainer 22, which is connected to the inlet port 2, for example, the strainer is connected between the first quick joint 21 and the inlet port 2, and filters the liquid entering the fluid control module to protect other components. Alternatively, the primary fluid flows into the fluid control module through the strainer, that is, the strainer is connected to the outside of the inlet port, and serves to protect the entire fluid control module.

[0065] Furthermore, the strainer 22 may be integrated with an anti-scaling and descaling unit.

[0066] The present invention further provides a thermal system, which includes any of the above-mentioned fluid control modules and a heat dissipation module or a cooling module (both not shown). The heat dissipation module and the cooling module have a pair of connection joints connected to the inlet port and the outlet port, and can be quickly connected to the fluid control module. The types of the heat dissipation module and the cooling module are not limited, and can be applied to central air conditioners, floor heating, etc.

[0067] 7, the present invention further provides a refrigeration system, which includes a compressor 04, a condenser 01 connected to an outlet of the compressor 04, an expansion valve 02 connected to an outlet of the condenser 01, and an evaporator 03 connected between the outlet of the expansion valve 02 and the inlet of the compressor 04. The refrigerant used in the refrigeration system is a natural refrigerant, which may be a hydrocarbon compound such as ethane, propane, propylene, butane, isobutane, and pentane.

[0068] The working principle of the refrigeration system: The compressor 04 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas, which is then condensed into a medium-temperature, high-pressure liquid in the condenser 01, and then throttled by the expansion valve 02 to become a low-temperature, low-pressure liquid. The low-temperature, low-pressure liquid medium is sent to the evaporator 03, where it absorbs heat and evaporates to become a low-temperature, low-pressure vapor, which is then sent back to the compressor, thus completing the refrigeration cycle.

[0069] In the above fluid control module, the heat exchanger 3 further includes a secondary fluid inlet 34, a secondary fluid outlet 35, and a secondary fluid flow path connecting the secondary fluid inlet 34 and the secondary fluid outlet 35. The fluid control module can function as the condenser, with the secondary fluid flow path connected in series between the outlet of the compressor 04 and the inlet of the expansion valve 02. Or, the fluid control module can function as an evaporator, with the secondary fluid flow path connected in series between the outlet of the expansion valve 02 and the inlet of the compressor 04.

[0070] After adopting the above-mentioned fluid control module, the overall structure of the refrigeration system is compact, the volume is small, and the installation space is greatly reduced. In addition, the flow path of the refrigerant in the refrigeration system is greatly shortened, and the amount of refrigerant used is greatly reduced. At the same time, the condenser is quickly cooled by the externally connected heat dissipation module, and the evaporator is quickly heated by the externally connected cooling module, so as to achieve a high-efficiency heat exchange and improve the cooling effect of the refrigeration system.

[0071] According to actual applications, the existing 5kW heat pump is composed of a copper tube aluminum fin and plate type heat exchanger 3, and the refrigerant charge is 1050g. Since 70% of the refrigerant charge belongs to the heat exchanger 3, the copper tube aluminum fin and plate type heat exchanger 3 of the heat exchanger 3 contains 735g of refrigerant. When the plate type heat exchanger 3 and the auxiliary connecting pipes are replaced with either a condenser or an evaporator using the above-mentioned fluid control module, the refrigerant charge becomes 800g, and the heat exchanger 3 of the fluid control module contains 560g of refrigerant. At this time, the amount of refrigerant used in the system is reduced by 250g, which is a 24% reduction, and at the same time, the coefficient of performance COP of the system is improved by 8 to 10% compared with the conventional system.

[0072] When the fluid control module is connected to a refrigeration system as a condenser, the secondary fluid inlet 34 is connected to the compressor outlet, and the secondary fluid outlet 35 is connected to the expansion valve inlet. The refrigerant releases heat to the outside as the secondary fluid, and the primary fluid absorbs heat, increasing its temperature, and supplies heat to the outside via the heat dissipation components.

[0073] When the fluid control module is connected to a refrigeration system as an evaporator, the secondary fluid outlet is connected to the expansion valve outlet, and the secondary fluid inlet is connected to the compressor inlet. The refrigerant absorbs heat from the primary fluid as the secondary fluid, and the primary fluid is cooled by heat dissipation, and supplies cold to the outside through the cooling component. When the fluid control module functions as an evaporator, the inlet and outlet of the refrigerant are exactly the opposite to when the fluid control module functions as a condenser. For example, the secondary fluid port 34 in FIG. 1 functions as the secondary fluid outlet of the evaporator, and the secondary fluid port 35 in FIG. 1 functions as the secondary fluid inlet of the evaporator.
