[0037] The following will be described in conjunction with Figures 1-4The embodiment of the utility model discloses.

[0038] According to the embodiment of the utility model, on the one hand, a kind of external uniform temperature device 1 is provided, and external uniform temperature device 1 includes cabinet 100, liquid storage module 200, cooling module 500, heating module 400, pump body 300 and switching valve group 600.

[0039] Liquid storage module 200, cooling module 500, heating module 400, pump body 300 and switching valve group 600 are all arranged in cabinet 100, and liquid storage module 200 is equipped with total outlet 201 and is used to store cooling liquid liquid storage cavity 202, total outlet 201 and liquid storage cavity 202 are communicated, and pump body 300 is equipped with total inlet 301.Cooling module 500 and heating module 400 are communicated between liquid storage module 200 and pump body 300, and heating module 400 forms heating flow channel with liquid storage module 200 and pump body 300, and cooling module 500 forms cooling flow channel with liquid storage module 200 and pump body 300, that is to say, cooling module 500 and heating module 400 are connected in parallel.

[0040] Switching valve group 600 is arranged in heating flow channel and cooling flow channel, and switching valve group 600 can be switched between first state and second state, and when switching valve group 600 is in first state, heating flow channel flows, and cooling flow channel is cut off;When switching valve group 600 is in second state, heating flow channel is cut off, and cooling flow channel flows.

[0041] Among them, liquid storage module 200 can be water tank.Heating module 400 can include semiconductor material or element (Positive Temperature Coefficient, PTC) with positive temperature coefficient or other devices with heating function, for example, heating module 400 can include thermistor.

[0042] For example, switching valve group 600 can include two-position three-way valve, and the first opening of two-position three-way valve is connected to heating module 400, the second opening is connected to cooling module 500, and the third opening is connected to pump body 300 or liquid storage module 200, and when switching valve group 600 is in first state, the first opening and the third opening are communicated, and when switching valve group 600 is in second state, the second opening and the third opening are communicated.

[0043] Alternatively, switching valve group 600 can include two two-position two-way valves, one end of the first two-position two-way valve is connected to heating module 400, and the other end is connected to pump body 300 or liquid storage module 200, one end of the second two-position two-way valve is connected to cooling module 500, and the other end is connected to pump body 300 or liquid storage module 200, when switching valve group 600 is in first state, the first two-position two-way valve is opened, and the second two-position two-way valve is closed, and when switching valve group 600 is in second state, the first two-position two-way valve is closed, and the second two-position two-way valve is opened.

[0044] It should be noted that the industrial vehicle and the engineering machinery can be provided with an internal flow channel, which is detachably connected with the total outlet 201 and the total inlet 301. When the internal flow channel is not connected with the total outlet 201 and the total inlet 301, the opening of the internal flow channel is in a closed state, and the total inlet 301 and the total outlet 301 are also in a closed state, so as to avoid the leakage of the cooling liquid. When the internal flow channel is connected with the total outlet 201 and the total inlet 301, the state of the switching valve group 600 can be controlled, so as to realize the communication between the internal flow channel and the cooling flow channel, or the communication between the internal flow channel and the heating flow channel, thereby realizing the heat exchange between the internal flow channel and the motor or the battery, and realizing the temperature control of the motor and the battery.

[0045] Specifically, when the temperature of the battery or the motor and the like in the industrial vehicle and the engineering machinery is high, the switching valve is in the first state, and the internal flow channel is in communication with the cooling flow channel. At this time, the pump body 300 is started, the cooling liquid in the liquid storage module 200 flows into the internal flow channel, the pump body 300 draws out the cooling liquid in the internal flow channel, the cooling liquid is cooled by the cooling module 500, and then flows into the internal flow channel through the liquid storage cavity 202 of the liquid storage module 200. The cooling liquid in the internal flow channel can be heat-exchanged with the battery or the motor and the like, so as to reduce the temperature of the battery or the motor and the like.

[0046] When the temperature of the battery or the motor and the like in the industrial vehicle and the engineering machinery is low, the switching valve is in the second state, and the internal flow channel is in communication with the heating flow channel. At this time, the pump body 300 is started, the cooling liquid in the liquid storage module 200 flows into the internal flow channel, the pump body 300 draws out the cooling liquid in the internal flow channel, the cooling liquid is heated by the heating module 400, and then flows into the internal flow channel through the liquid storage cavity 202 of the liquid storage module 200. The cooling liquid in the internal flow channel can be heat-exchanged with the battery or the motor and the like, so as to increase the temperature of the battery or the motor and the like.

[0047] Through the external uniform temperature device 1, the temperature of the battery or the motor and the like in the industrial vehicle and the engineering machinery can be adjusted, so as to maintain the working performance of the above-mentioned devices at a high state, prolong the service life of the above-mentioned devices, and improve the use safety of the above-mentioned devices. Moreover, the internal part of the industrial vehicle and the engineering machinery does not need to be provided with a complete cooling system, but only needs to be integrated with an internal flow channel, for example, a cooling plate can be provided, and of course other structures with flow channels can also be provided. The number of parts required by the industrial vehicle and the engineering machinery is reduced, the weight, cost and volume of the industrial vehicle and the engineering machinery are reduced, and the endurance of the industrial vehicle and the engineering machinery is improved.

[0048] In addition, the volume and shape of the external temperature equalizing device 1 are not limited by the internal space of the industrial vehicle or engineering machinery, so that the cooling and heating effects of the external temperature equalizing device 1 can be optimized, and the maintenance of the external temperature equalizing device 1 is more convenient. In addition, the movement of the external temperature equalizing device 1 is not limited, and one external temperature equalizing device 1 can heat or cool different vehicles or machinery, so that the use of the external temperature equalizing device 1 is more flexible.

[0049] In addition, since the industrial vehicle or engineering machinery may need to move during use, the external temperature equalizing device 1 is connected with the internal flow channel when the industrial vehicle or engineering machinery stops moving, so that the leakage of the cooling liquid can be avoided.

[0050] As shown in Figure 1 In some embodiments, the external temperature equalizing device 1 further includes a liquid inlet pipe 700, a liquid outlet pipe 800, a liquid inlet valve 710 and a liquid outlet valve 810. The liquid inlet pipe 700 is in communication with the total inlet 301, the liquid outlet pipe 800 is in communication with the total outlet 201, the liquid inlet valve 710 is arranged in at least one of the liquid inlet pipe 700 and the pump body 300, and the liquid outlet valve 810 is arranged in at least one of the liquid outlet pipe 800 and the liquid storage module 200.

[0051] For example, the liquid inlet pipe 700 and the pump body 300 can be detachably connected, or the liquid inlet pipe 700 and the pump body 300 can be configured as an integral structure; the liquid outlet pipe 800 and the liquid storage module 200 can be detachably connected, or the liquid outlet pipe 800 and the liquid storage module 200 can be configured as an integral structure. The liquid inlet pipe 700 and the liquid outlet pipe 800 adopt a pipe line resistant to high temperature and corrosion.

[0052] In addition, the liquid inlet pipe 700 and the internal flow channel can be detachably connected, and the liquid outlet pipe 800 and the internal flow channel can be detachably connected. For example, the liquid inlet pipe 700 and the liquid outlet pipe 800 adopt quick-change joints to realize quick insertion and quick detachment with the internal flow channel.

[0053] By arranging the liquid inlet pipe 700 and the liquid outlet pipe 800, the relative position between the external temperature equalizing device 1 and the internal flow channel can be adjusted, and the arrangement of the external temperature equalizing device 1 is more flexible. In addition, the liquid inlet pipe 700 and the liquid outlet pipe 800 can be arranged as 1, 2, 3 or more, and the number of the liquid inlet pipe 700 and the number of the liquid outlet pipe 800 are the same.

[0054] Specifically, when the inlet pipe 700 and the outlet pipe 800 are one-way, the external temperature equalization device 1 can only be connected to one internal flow channel at the same time; when the inlet pipe 700 and the outlet pipe 800 are two-way, the external temperature equalization device 1 can be connected to a maximum of two internal flow channels at the same time; when the inlet pipe 700 and the outlet pipe 800 are three-way, the external temperature equalization device 1 can be connected to a maximum of three internal flow channels at the same time, and so on. The external temperature equalization device 1 can connect to a maximum number of internal flow channels at the same time, equal to the number of inlet pipes 700 and the outlet pipe 800.

[0055] By setting the number of inlet pipes 700 and outlet pipes 800, an external temperature equalization device 1 can simultaneously regulate the temperature of batteries or motors of multiple mechanical devices (vehicles or construction machinery), making the external temperature equalization device 1 more efficient.

[0056] In addition, by setting the outlet valve 810 and the inlet valve 710, the total inlet 301 and the total outlet 201 can be closed and opened, thus preventing coolant leakage.

[0057] In some embodiments, the cooling module 500 includes a heat sink and a fan. The heat sink is disposed within the chassis 100 and has a heat dissipation channel, which connects the liquid storage module 200 and the pump body 300. The fan is disposed within the chassis 100 and guides the gas flow to the heat sink.

[0058] By installing a fan, the airflow speed in the area where the heat sink is located can be increased, thereby increasing the heat exchange efficiency between the heat sink and the air, and improving the cooling rate of the coolant in the heat dissipation channel. Furthermore, by installing heat sinks, the heat dissipation area of ​​the cooling module 500 can be increased, further increasing the heat exchange efficiency between the heat sink and the air, and improving the cooling rate of the coolant in the heat dissipation channel.

[0059] Furthermore, such as Figure 3 As shown, the chassis 100 is provided with a ventilation area 110, and the ventilation area 110 is provided with at least one ventilation hole 111. Specifically, the ventilation area 110 is located on the side wall of the chassis 100, and the projection of the fan in the horizontal direction toward the ventilation area 110 is at least partially located within the ventilation area 110; or, the ventilation area 110 is located on the top wall of the chassis 100, and the projection of the fan in the vertical direction toward the ventilation area 110 is at least partially located within the ventilation area 110.

[0060] For example, the ventilation zone 110 may have one large ventilation hole 111, or the ventilation zone 110 may have multiple ventilation holes 111, spaced apart from each other. This allows for the exchange of air between the inside and outside of the chassis 100, preventing heat from accumulating inside the chassis 100.

[0061] In addition, the fan and the position of the air-permeable area 110 are correspondingly arranged, the fan can guide the external air to the heat dissipation fins, improve the air exchange efficiency between the inside and outside of the case 100, and further improve the heat dissipation efficiency of the cooling module 500.

[0062] As shown in Figure 1 and Figure 3 In some embodiments, the external temperature equalizing device 1 further comprises a control button 120, the control button 120 is arranged on the case 100, and the control button 120 is connected with at least one of the pump body 300, the switching valve group 600, the fan, the liquid inlet valve 710 and the liquid outlet valve 810.

[0063] In this way, the control button 120 adjusts the opening, closing and working power of the pump body 300 and the fan, the flow and pressure of the pump body 300 can be adjusted according to the temperature control requirement, and the rotating speed of the fan can be adjusted according to the heat dissipation requirement, thereby improving the temperature adjustment effect. In addition, the control button 120 can control the switching valve group 600 to switch between the first state and the second state, and the control button 120 can also control the opening degree of the liquid inlet valve 710 and the liquid outlet valve 810 to adjust the flow of the cooling liquid, thereby further improving the temperature adjustment effect.

[0064] As shown in Figure 1 In some embodiments, the external temperature equalizing device 1 further comprises a power supply 900, the power supply 900 is arranged on the case 100, and the power supply 900 is connected with at least one of the switching valve, the fan, the liquid inlet valve 710 and the liquid outlet valve 810. The power supply 900 can be charged and discharged, for example, the power supply 900 can be charged by a 220V plug.

[0065] In this way, the power supply of the external temperature equalizing device 1 is more convenient, which is conducive to improving the endurance of the external temperature equalizing device 1.

[0066] As shown in Figure 2 In some embodiments, the liquid storage module 200 is provided with a filling port 203, and the filling port 203 is in communication with the liquid storage cavity 202. The filling port 203 can be arranged on the upper cavity wall of the liquid storage cavity 202, so as to reduce the probability of overflow of the cooling liquid in the liquid storage cavity 202 from the filling port 203. By arranging the filling port 203, the cooling liquid in the liquid storage cavity 202 can be supplemented in time.

[0067] Specifically, the liquid storage module 200 is detachably connected with the case 100, so that when the cooling liquid in the liquid storage module 200 is less, the liquid storage module 200 can be detached, and then the cooling liquid can be filled into the liquid storage cavity 202 through the filling opening 203; or the case 100 is provided with a filling flow channel, the filling flow channel is in communication with the filling opening 203, and when the cooling liquid in the liquid storage module 200 is less, the cooling liquid can be filled into the liquid storage cavity 202 through the filling flow channel and the filling opening 203; or the case 100 is provided with an open port, and the case 100 is provided with a movable cover plate, when the cooling liquid in the liquid storage module 200 is less, the cover plate is opened to expose the filling opening 203, and then the cooling liquid is filled into the liquid storage cavity 202 through the filling opening 203, and after the cooling and filling, the cover plate is closed to prevent impurities such as dust and liquid from entering the case 100 or the liquid storage cavity 202; or the part of the liquid storage module 200 provided with the filling opening 203 extends out of the case 100, and when the cooling liquid in the liquid storage module 200 is less, the liquid storage module 200 does not need to be detached, and the cooling liquid can be filled into the liquid storage cavity 202 through the filling opening 203.

[0068] It should be noted that the above several methods can be used alone or in combination with at least two of them.
