[0002] A heat exchange device is a device that transfers or exchanges heat from a heat dissipating body to another heat absorbing body. Common heat exchange devices include plate heat exchangers, which can transfer part of the heat of a hot fluid to a cold fluid to complete the heat dissipation or heat exchange function.

[0003] Heat exchange devices are often needed in operating machinery, such as electric loaders in construction machinery, which usually use plate heat exchangers to exchange heat for batteries to achieve the effect of cooling. At present, most heat exchangers are suspended and fixed on the frame through a rear plate or vertical plate. The weight of the heat exchanger is not shared at its bottom and transferred downward, and the overall installation structure has poor stability. In addition, the operating scene of construction machinery is relatively harsh, and the body vibrates violently during operation.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two groups, such as two groups, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two groups of components or the interaction relationship between two groups of components, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Please refer to Figure 1 According to the first aspect of the utility model, the utility model provides a heat exchange device installation structure, which is used to install the heat exchange device on the frame of the working machine, and specifically includes: an L-shaped plate and a base. Specifically, the heat exchange device is first installed on the L-shaped plate, and the heat exchange device is fitted with the vertical plate and the horizontal plate of the L-shaped plate, and then the L-shaped plate with the heat exchange device installed is installed on the base, and finally the integral structure of the heat exchange device, the L-shaped plate and the base is installed on the frame of the working machine.

[0042] In the prior art, the heat exchange device is generally suspended and fixed on the frame by a vertical plate. The heat exchange device's own gravity and the impact force caused by the vibration of the vehicle body are completely borne by this suspension vertical plate. There are few stress points and a small stress area, which leads to excessive pressure on the suspension vertical plate, which is easy to cause problems such as loosening. In the installation structure provided by the utility model, the utility model proposes to combine the L-shaped plate with the base to jointly form the installation structure of the heat exchange device. The heat exchange device is installed on the L-shaped plate and fits with the vertical plate and the horizontal plate of the L-shaped plate respectively. It can be understood that the heat exchange device is fitted with the vertical plate and the horizontal plate of the L-shaped plate, which means that the heat exchange device has direct or indirect contact with the vertical plate and the horizontal plate of the L-shaped plate, so the forces on the heat exchange device in all directions can be transmitted to the vertical plate and the horizontal plate of the L-shaped plate. Specifically, in the vertical direction, the weight of the heat exchange device itself and other vertical impact forces are borne by the horizontal plate and the base of the L-shaped plate, and finally transmitted to the frame. Obviously, the ability of the L-shaped plate, the base and the frame to jointly bear the vertical force of the heat exchange device is definitely better than the single hanging vertical plate and other similar installation structures in the prior art. In addition, in the horizontal direction (the horizontal direction relative to the above-mentioned vertical direction), the heat exchange device can transmit the horizontal force to the vertical plate of the L-shaped plate, wherein the vertical plate of the L-shaped plate can be further connected to other devices or frames according to the actual conditions such as the vehicle type and installation space of the specific operating machinery to further enhance stability; but regardless of whether other structures are further connected, because the L-shaped plate is fixed to the base, and the base is fixed to the frame, the stability of the L-shaped plate is strong enough to withstand the horizontal force of the heat exchange device and still maintain relative stability. In summary, the installation structure of the heat exchange device provided by the utility model improves the problems of simple installation structure and poor stability in the prior art.

[0043] Please refer to Figure 1 In one embodiment, the heat exchange device is vertically mounted on the L-shaped plate and fixedly connected to the vertical plate of the L-shaped plate, and a shock-absorbing pad is provided between the bottom of the heat exchange device and the horizontal plate of the L-shaped plate. It is understandable that the fixed connection includes a detachable and non-detachable connection, such as a fixed connection by bolts, or the heat exchange device can be directly welded to the vertical plate of the L-shaped plate. After the heat exchange device is fixedly connected to the vertical plate of the L-shaped plate, the stability of the heat exchange device can be further enhanced to withstand the impact force and force in the horizontal direction of the heat exchange device. Ideally, the heat exchange device can be vertically mounted on the L-shaped plate, and the vertical installation can help the heat exchanger and the L-shaped plate to fit better and further enhance stability. It is optional whether the horizontal plate of the L-shaped plate is fixedly connected to the heat exchange device. In this embodiment, it is preferred not to perform a fixed connection, and a shock-absorbing pad is further provided between the bottom of the heat exchange device and the horizontal plate of the L-shaped plate. The shock-absorbing pad can help the L-shaped plate buffer the impact force from the vertical direction of the heat exchange device, reduce the pressure on the L-shaped plate, and extend the service life of the mounting structure.

[0044] Please refer to Figure 1 In one embodiment, the heat exchange device is fixed to the vertical plate of the L-shaped plate by welding, and the shock-absorbing pad provided between the heat exchange device and the horizontal plate of the L-shaped plate is a rubber assembly. In the above embodiment, it has been explained that the connection between the heat exchange device and the vertical plate of the L-shaped plate can be a detachable or non-detachable connection, but in actual operation, considering that some operating machinery has large vibrations, it is preferably fixed by welding. The welding form has good integrity and improved durability. The shock-absorbing pad provided between the heat exchange device and the horizontal plate of the L-shaped plate is a rubber assembly, and the rubber assembly can be laid flat on the horizontal plate of the L-shaped plate, or fixed on the horizontal plate of the L-shaped plate, and its area can be set as required according to the bottom area of ​​the heat exchange device and the actual situation of the operating machinery. In addition, the rubber assembly can be a combination of rubber material and any hard material, such as a combination of rubber and metal material. The metal material can relatively fix its shape to prevent excessive deformation after being stressed; its thickness can be set as required according to the size and weight of the heat exchange device and the use scenario of the operating machinery.

[0045] Please refer to Figure 1 In one embodiment, the horizontal plate of the L-shaped plate is fixedly connected to the base by bolts. It is understandable that there are many ways to connect the horizontal plate of the L-shaped plate to the base, which can be divided into detachable connection and non-detachable connection. In short, it is sufficient to fix the two. Preferably, in this example, the horizontal plate of the L-shaped plate and the base are detachably connected by bolts. Bolts are one of the most common fasteners, with mature technology, convenient equipment of related parts, and relatively low cost connection.

[0046] Please refer to Figure 1 and Figure 2 In one embodiment, at least two mounting holes are provided on the horizontal plate of the L-shaped plate, and corresponding through holes are provided on the base to facilitate bolts to pass through the mounting holes and the through holes to fix the L-shaped plate to the base. It is understandable that the reliability and stability of more than two mounting holes, that is, using more than two bolts to fix the L-shaped plate to the base is obviously much stronger than fixing it with a single bolt. In addition, the overall volume and bottom area of ​​the heat exchange device are generally not too small, so using more than two bolts for fixing is the choice of most people / manufacturers, unless the two are not fixed with bolts.

[0047] Please refer to Figure 1 and Figure 2In one embodiment, the bolt mounting holes provided on the horizontal plate and the base of the L-shaped plate are waist-shaped holes. Under normal circumstances, when installing the bolts, it is generally only necessary to match the ordinary through holes of the corresponding size / dimension / diameter, and the bolts can pass through the through holes for normal installation. However, in the actual installation process, since the bolts need to pass through two mounting plates (L-shaped plate and base), there may be tolerances in the positions of the corresponding mounting holes of the two mounting plates, which may affect the normal installation. In view of this, the present embodiment preferably sets the mounting holes on the L-shaped plate as waist-shaped holes, and the corresponding through holes on the base can be designed as ordinary through holes or waist-shaped holes as required. It can be understood that the waist-shaped hole allows the bolt to move appropriately in the setting direction of the waist-shaped hole, or to move the entire L-shaped plate so that the mounting hole (waist-shaped hole) of the L-shaped plate is aligned with the mounting hole of the base, so as to facilitate the insertion and installation of the bolt. The setting of the waist-shaped hole helps to adjust the tolerance between the mounting holes between the L-shaped plate and the base, thereby improving the assembly efficiency.

[0048] Please refer to Figure 1 and Figure 2 In one embodiment, the bolt passes through the mounting holes of the L-shaped plate and the base and cooperates with the nut to fix the L-shaped plate and the base, and a gasket is provided between the nut and the base. The number of the gaskets can be one or more, and the gasket is used to protect the mounting surface of the base from being damaged by excessive tightening of the bolts. It is understandable that the gasket must be provided with a through hole to facilitate the bolt to pass through the gasket; in addition, regarding the material of the gasket, common ones such as metal gaskets or other polymer gaskets can be used as long as they can withstand the pressure brought by the bolts. Regarding the installation position of the gasket, this embodiment preferably sets the gasket at the matching gap between the nut and the base to protect the mounting surface of the base from being damaged by excessive tightening of the bolts. As for the matching gap between the bolt and the L-shaped plate, whether to set the gasket can be considered as needed; in addition, considering the aesthetics of the assembly, a sunken mounting hole can also be set on the mounting surface of the L-shaped plate, so that the cap end of the bolt can be hidden in the sunken mounting hole, and the aesthetics of the mounting surface of the L-shaped plate is better.

[0049] Please refer to Figure 1 and Figure 3In the second aspect of the utility model, the utility model provides a heat exchange device, which is fixed to the frame of the operating machinery with any of the above-mentioned mounting structures. It can be understood that the heat exchange device is a device that transfers or exchanges the heat of a heat dissipating body to another heat absorbing body. Common heat exchange devices such as plate heat exchangers can transfer part of the heat of a hot fluid to a cold fluid to complete the heat dissipation or heat exchange function. Heat exchange devices are often needed in operating machinery, such as electric loaders in engineering machinery, which usually use plate heat exchangers to exchange heat for batteries to achieve the effect of cooling. At present, most heat exchangers are suspended and fixed on the frame through a rear plate or a vertical plate. The weight of the heat exchanger is not shared to its bottom and transferred downward, and the overall mounting structure has poor stability; and the operating scene of engineering machinery is relatively harsh, and the body vibrates violently during operation, so the heat exchanger fixing plate is often loosened, welded, etc., which further leads to problems such as leakage of antifreeze in the heat exchanger and failure of the battery to cool normally. The heat exchange device provided by the present invention is fixed by any of the above-mentioned installation structures, and its reliability and stability are both stronger. This aspect has been described in detail in the embodiments of the above-mentioned installation structures.

[0050] Please refer to Figure 1 and Figure 3 In one embodiment, the heat exchange device further comprises an electronic expansion valve, the electronic expansion valve is fixedly connected to the extension pipeline of the heat exchange device, and a shock-absorbing pad is provided between the electronic expansion valve and the L-shaped plate in any of the above-mentioned mounting structures. Figure 3 One end face of the heat exchange device is provided with a pipeline extending outward, which is further connected to the electronic expansion valve. The electronic expansion valve is also fixed to the heat exchange device and installed on the L-shaped plate together with the heat exchange device as a whole, saving the separate installation space of the electronic expansion valve. On the other hand, the electronic expansion valve is a relatively mature existing technology and a standard part that can be directly purchased from the market. It is used to control the amount of cold or heat entering the heat exchange device. The cold or heat can be in liquid form, gas form or gas-liquid mixed state. The amount of cold or heat entering the heat exchange device is controlled by controlling the opening of the electronic expansion valve.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3In the third aspect of the utility model, the utility model provides a working machine, the working machine includes any of the above-mentioned heat exchange devices. It can be understood that the working machine refers to a mechanical device or mechanical equipment that can perform construction operations, such as loaders, excavators, bulldozers, rollers, etc. The working machine provided by the utility model uses any of the above-mentioned heat exchange devices, and the heat exchange device is fixed to the frame of the working machine with any of the above-mentioned mounting structures. Based on the description of the embodiments of the above-mentioned heat exchange device and the mounting structure, it can be known that the working machine that fixes any of the above-mentioned heat exchange devices with any of the above-mentioned mounting structures has better stability and stronger reliability.

[0052] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
