[0001] This application relates to the technical field of household appliances, for example, to a heat exchanger installation assembly, a heat exchanger, and an air conditioner. Background Art

[0002] With the substantial improvement of the national economy, people's living standards have also been greatly improved. Especially in the choice of water heaters, people's requirements for comfort and health are getting higher and higher. Traditional water heaters generally include gas water heaters, electric water heaters, and solar water heaters, etc. However, gas water heaters may have safety hazards such as poor exhaust ventilation and pipeline air leakage; electric water heaters have disadvantages such as low heating efficiency and high energy consumption; solar water heaters are easily affected by the weather and cannot operate normally without sunlight. At the same time, the popularity rate of current air conditioners has been greatly improved, but air conditioners are almost idle in spring and autumn, and a large amount of waste heat is generated by air conditioners in summer.

[0003] In the related art, such as the invention with the patent publication number CN101655281B and the patent name of heat pump hot water air conditioner unit and its working method, a heat pump hot water air conditioner that combines a water heater and an air conditioner is disclosed. In this way, when the air conditioner is heating or cooling, the heat generated by the air conditioner can be used to heat the water in the heat exchanger water tank, which is more energy-saving and environmentally friendly.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the related art, existing heat pump hot water air conditioners may combine the heat exchange units of outdoor heat exchangers and indoor heat exchangers, that is, integral heat pump hot water air conditioners. Since the outdoor heat exchanger of the air conditioner is compatible with the heat exchange units of the indoor heat exchanger, more system components of the fluorine system of the outdoor heat exchanger need to be installed and fixed, which will increase the assembly process and reduce the assembly efficiency.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0040] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0041] Most heat pump water air conditioners on the market currently are composed of an outdoor heat exchanger and an indoor heat exchanger, and the indoor heat exchanger includes a heat exchange unit. In order to facilitate installation and reduce the space required for installation, some heat pump water air conditioners will combine the outdoor heat exchanger and the indoor heat exchanger, that is, an integrated heat pump water air conditioner.

[0042] However, since the outdoor heat exchanger incorporates the heat exchange unit of the indoor heat exchanger, more system components need to be installed and fixed in the fluorine system of the outdoor heat exchanger, increasing the assembly process and reducing the installation efficiency. Therefore, how to efficiently manufacture and install an integrated heat pump water air conditioner has become a common problem in the industry.

[0043] Such as Figures 1 to 6As shown, an embodiment of the present disclosure provides a heat exchanger installation assembly 05, a heat exchanger, and an air conditioner. A user can first install the system components of the heat exchanger on the heat exchanger installation assembly 05, and then install the heat exchanger installation assembly 05 and the system components together on the heat exchanger. With this arrangement, the assembly process of the heat exchanger is reduced, and the assembly efficiency is improved.

[0044] As Figures 1 to 6 shown, an embodiment of the present disclosure provides a heat exchanger installation assembly 05, which is applied to a heat exchanger. The heat exchanger includes a machine cabin 01, a plate heat exchanger group 02, an expansion tank group 03, and a water pump assembly 04. The above heat exchanger installation assembly 05 includes: a support plate 10, a mounting plate 20, and a water pump fixing member 12. The support plate 10 is detachably installed in the machine cabin 01. The support plate 10 is a bent structure to enclose a hollow installation area 11, and the installation area 11 is used for installing the plate heat exchanger group 02; the mounting plate 20 is installed on the outer side wall surface of the support plate 10, and the mounting plate 20 is provided with a mounting surface, and the mounting surface is used for installing the expansion tank group 03; the water pump fixing member 12 is detachably installed on the outer side wall surface of the support plate 10, and is used to fix the water pump assembly 04 on the outer side wall surface of the support plate 10.

[0045] Specifically, the machine cabin 01 is provided with a heat exchange installation cavity, and the support plate 10 is detachably installed in the heat exchange installation cavity, as Figure 1 shown. The side wall surface of the mounting plate 20 facing away from the support plate 10 can be used as the mounting surface. When installing the heat exchanger, a user can first install the mounting plate 20 on the outer side surface of the support plate 10, and then install the expansion tank group 03 on the mounting surface of the mounting plate 20. Alternatively, the expansion tank group 03 can also be first installed on the mounting surface of the mounting plate 20, and then the expansion tank group 03 and the mounting plate 20 are installed on the support plate 10 together to install the expansion tank group 03 on the support plate 10. At the same time, the user can install the plate heat exchanger group 02 in the installation area 11 enclosed by the support plate 10, and use the water pump fixing member 12 to fixedly install the water pump assembly 04 on the outer side wall surface of the support plate 10. After installing the expansion tank group 03, the plate heat exchanger group 02, and the water pump assembly 04 on the support plate 10, the user can install the support plate 10 in the heat exchange installation cavity of the machine cabin 01 to install the expansion tank group 03, the plate heat exchanger group 02, and the water pump assembly 04 in the heat exchange installation cavity. With this arrangement, the assembly process of the heat exchanger is reduced, and the assembly efficiency is improved.

[0046] At the same time, installing the plate heat exchanger group 02 in the installation area 11 enclosed by the support plate 10 can also isolate the plate heat exchanger group 02 from other components of the heat exchanger, so as to prevent the plate heat exchanger group 02 from coming into contact with other components of the heat exchanger, and improve the service life of the plate heat exchanger.

[0047] It can be understood that generally the integral structure is relatively compact, resulting in a relatively small space inside the engine room 01. Therefore, if it is necessary to replace or maintain components such as the expansion tank group 03, the plate heat exchanger group 02, and the water pump assembly 04, the corresponding components need to be removed separately, and then reinstalled into the engine room 01 after replacement or maintenance, which is rather cumbersome in operation. By using the heat exchanger installation assembly 05 provided in the present application, the user can directly take out the support plate 10 from the engine room 01, and then replace or maintain the corresponding components, making the operation more convenient.

[0048] As Figure 2 and Figure 3 shown, in some practical applications, the water pump assembly 04 includes an inlet pipe and an outlet pipe. There are two sets of water pump fixing members 12, and the two sets are respectively arranged corresponding to the inlet pipe and the outlet pipe. The water pump fixing member 12 includes a limiting portion and a fastening portion, and the fastening portions are located on both sides of the limiting portion. The shapes of the limiting portions of the two sets of water pump fixing members 12 are respectively arranged corresponding to the inlet pipe and the outlet pipe. After placing the water pump assembly 04 on the outer side wall surface of the support plate 10, one set of water pump fixing members 12 can be made to abut against the inlet pipe from the outside of the inlet pipe, and the other set of water pump fixing members 12 can be made to abut against the outlet pipe from the outside of the outlet pipe, and the fastening portions of the two sets of water pump fixing members 12 are respectively installed on the support plate 10 by using fasteners.

[0049] In some embodiments, the mounting plate 20 is further provided with a first clamping portion, and the first clamping portion is arranged on the other side of the mounting plate 20 relative to the mounting surface; the support plate 10 is correspondingly provided with a first clamping and cooperating portion for the first clamping portion; wherein, the first clamping portion can be clamped in the first clamping and cooperating portion to enable the mounting plate 20 to be clamped to the support plate 10.

[0050] Specifically, the first clamping and cooperating portion is arranged on the side wall surface of the support plate 10, and the first clamping portion is arranged at a position corresponding to the first clamping and cooperating portion on the mounting plate 20. If the user needs to install the expansion tank group 03, the user can first install the expansion tank group 03 on the mounting surface of the mounting plate 20, and then clamp the first clamping portion of the mounting plate 20 in the first clamping and cooperating portion of the support plate 10 to install the expansion tank group 03 on the support plate 10. If the user needs to remove the expansion tank group 03, the first clamping portion can also be first disengaged from the first clamping and cooperating portion, and then the expansion tank group 03 can be removed from the mounting plate 20. With such a setting, the user can install or disassemble the expansion tank group 03 without taking out the support plate 10 from the engine room 01, further reducing the assembly process of the heat exchanger and improving the assembly efficiency.

[0051] As Figures 3 to 5 shown, in some embodiments, the mounting plate 20 is provided with a buckle 21 to form the first clamping portion; the support plate 10 is correspondingly provided with a slot 13 for the buckle 21 to form the first clamping and cooperating portion.

[0052] Specifically, the buckle 21 is arranged on the other side of the mounting plate 20 relative to the mounting surface, and a groove is arranged above the side wall of the support plate 10 to form a buckle slot 13. The buckle 21 can be engaged in the buckle slot 13 to engage the mounting plate 20 with the support plate 10, or the buckle 21 can be disengaged from the buckle slot 13 to disengage the mounting plate 20 from the support plate 10.

[0053] Optionally, the buckle 21 corresponds to the size of the slot 13. In this way, when the buckle 21 is engaged with the slot 13, the slot 13 and the buckle 21 abut against each other to prevent the installation plate 20 from being displaced.

[0054] like Figures 3 to 5 As shown, in some practical applications, a groove is provided on the upper edge of a side wall surface of the support plate 10 to form a slot 13. A buckle 21 is provided at a position of the support plate 10 corresponding to the slot 13, and an opening is provided at the lower end of the buckle 21. After the expansion tank assembly 03 is mounted on the mounting plate 20, the buckle 21 can be inserted into the slot 13 through the opening of the buckle 21. At this time, the buckle 21 clamps the side wall surface of the support plate 10 to prevent the mounting plate 20 from falling off the support plate 10. At the same time, the slot 13 abuts against the edge of the buckle 21 to prevent the buckle 21 from shaking.

[0055] In some embodiments, the size of the installation area 11 is larger than the size of the plate heat exchanger group 02 ; when the plate heat exchanger is installed in the installation area 11 , there is a gap between the plate heat exchanger and the support plate 10 .

[0056] Specifically, the size of the installation area 11 is made larger than the size of the plate heat exchanger group 02, so that it is more convenient for users to install or remove the plate heat exchanger group 02. Wherein, when the plate heat exchanger is installed in the installation area 11, the distance between the plate heat exchanger and the support plate 10 is greater than or equal to 1 mm. For example, the distance between the plate heat exchanger and the support plate 10 can be 1 mm, 2 mm, 3 mm, 4 mm or 5 mm.

[0057] It is understandable that during the operation of the plate heat exchanger, the plate heat exchanger may vibrate. At this time, if the plate heat exchanger contacts the support plate 10 or other parts of the heat exchanger, resonance noise may be generated, resulting in a poor user experience. Therefore, by making the support plate 10 enclose the installation area 11 and leaving a gap between the plate heat exchanger and the support plate 10, the plate heat exchanger can be prevented from contacting the support plate 10 or other parts of the heat exchanger, thereby avoiding resonance noise and improving the user experience.

[0058] like Figure 6 As shown, in some embodiments, the heat exchanger installation assembly 05 further includes a support member 14. The support member 14 is used to support the plate heat exchanger group 02 to prevent the lower end surface of the plate heat exchanger group 02 from contacting the cabin 01.

[0059] Specifically, the support member 14 is installed on the support plate 10. After the plate heat exchanger group 02 is installed in the installation area 11, the support member 14 can be made into the plate heat exchanger group 02 so that the plate heat exchanger group 02 is in a suspended state. With such a setting, it is possible to prevent the lower end surface of the plate heat exchanger group 02 from contacting the engine room 01, and further prevent the plate heat exchanger group 02 from generating resonance noise with the engine room 01 during operation.

[0060] As Figure 6 shown, in some embodiments, the support plate 10 is provided with through holes, and slots are provided at positions corresponding to the through holes of the plate heat exchanger group 02; wherein, the support member 14 can pass through the through holes from the outside of the support plate 10 and be inserted into the slots.

[0061] Specifically, the support member 14 is of a cylindrical structure and its dimensions correspond to the through holes and the slots. After the plate heat exchanger group 02 is installed in the installation area 11, the positions of the slots and the through holes correspond to each other. At this time, the support member 14 is passed through the through holes and inserted into the slots to support the plate heat exchanger.

[0062] In some embodiments, the support plate 10 is further provided with a handle.

[0063] Specifically, the handle is arranged on the side wall surface of the support plate 10. In this way, the user can place the support plate 10 in the engine room 01 or take it out of the engine room 01 through the handle, further improving the assembly efficiency.

[0064] Optionally, the support plate 10 is provided with two groups of handles, and the two groups of handles are relatively located on both sides of the support plate 10.

[0065] As Figure 1 shown, an embodiment of the present disclosure further provides a heat exchanger, including: an engine room 01, a plate heat exchanger group 02, an expansion tank group 03, a water pump assembly 04, and the above-mentioned heat exchanger installation assembly 05; wherein, the plate heat exchanger group 02, the expansion tank group 03, and the water pump assembly 04 can be installed on the heat exchanger installation assembly 05, and the heat exchanger installation assembly 05 is detachably installed in the engine room 01.

[0066] Specifically, for the heat exchanger adopting the heat exchanger installation assembly 05 provided by the present application, when installing the heat exchanger, the user can first install the expansion tank group 03 on the mounting plate 20, and after installing the plate heat exchanger group 02 and the water pump assembly 04 on the support plate 10, install the support plate 10 in the engine room 01 of the heat exchanger. If the user needs to repair or replace the plate heat exchanger group 02, the expansion tank group 03, and the water pump assembly 04, the support plate 10 can also be taken out of the engine room 01 first, and then the plate heat exchanger group 02, the expansion tank group 03, and the water pump assembly 04 can be replaced or maintained. With such a setting, the assembly process of the heat exchanger is reduced, and the assembly efficiency is improved.

[0067] In some embodiments, the support plate 10 is further provided with a second clamping portion; the engine compartment 01 is provided with a second clamping and mating portion corresponding to the second clamping portion; wherein, the second clamping portion can be clamped to the second clamping and mating portion so that the support plate 10 is clamped to the engine compartment 01.

[0068] Specifically, a tab is provided at the lower end of the support plate 10 to form the second clamping portion, and a slot is provided at the position of the engine compartment 01 corresponding to the tab to form the second clamping and mating portion. After the support plate 10 is placed in the engine compartment 01, the tab can be inserted into the slot to clamp the support plate 10 in the engine compartment 01.

[0069] In practical applications, after the support plate 10 is clamped to the engine compartment 01, the support plate 10 can also be fixed to the engine compartment 01 by fasteners such as bolts or screws.

[0070] As Figure 1 shown, the embodiments of the present disclosure also provide an air conditioner including: the above-mentioned heat exchanger.

[0071] Specifically, the air conditioner is an integrated heat pump water heater air conditioner.

[0072] The air conditioner adopting the heat exchanger provided by the present application reduces the assembly process of the heat exchanger and improves the assembly efficiency.

Unless explicitly required, the individual components and functions are optional, and the order of operations can vary.
