For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0035] The following will further describe the present utility model in detail through specific embodiments in conjunction with the accompanying drawings.
[0036] See Figure 1 、 Figure 2 and Figure 3 As shown in, this embodiment provides a chain saw heat dissipation and cooling structure, including a chain saw housing 100, a cooling fan and a controller; an installation seat for installing the cooling fan is arranged in the chain saw housing 100, and the cooling fan faces the motor inside the chain saw housing 100; an installation groove 110 for installing the controller is arranged in the chain saw housing 100, an air inlet 120 is opened at the position of the chain saw housing 100 where the installation groove 110 is located, and an exhaust port 130 is opened at the bottom of the chain saw housing 100.
[0037] Specifically, when the cooling fan works, the air flow outside the chain saw housing 100 can be introduced into the chain saw housing 100 from the air inlet 120. The air flow can blow onto the controller, and then dissipate heat from the motor inside the chain saw housing 100, and finally discharge from the exhaust port 130. By synchronously cooling the controller and the motor through the cooling fan, the chain saw can work for a long time.
[0038] See Figure 1 、 Figure 2 and Figure 3 As shown in, in an alternative solution of this embodiment, a heat dissipation plate 200 is arranged on the controller.
[0039] Specifically, a heat dissipation plate 200 is arranged on the controller. Through the arrangement of the heat dissipation plate 200, the heat generated on the controller can be quickly transferred to the heat dissipation plate 200. At the same time, during subsequent daily use, the air flow inhaled by the cooling fan can directly dissipate heat from the heat dissipation plate 200 and will not directly blow onto the controller, so that dust will not accumulate on the controller or the controller will not be damaged by strong wind. Therefore, the damage probability of the controller is reduced.
[0040] See Figure 1 、 Figure 2 and Figure 3 As shown in, in an alternative solution of this embodiment, a plurality of heat dissipation fins are arranged on the heat dissipation plate 200.
[0041] Specifically, a plurality of heat dissipation fins are provided on the heat dissipation plate 200, and the plurality of heat dissipation fins are arranged on the heat dissipation plate 200 at equal intervals. By providing the heat dissipation fins, the heat exchange efficiency between the heat dissipation plate 200 and the air can be effectively improved, thereby improving the heat dissipation efficiency and effect.
[0042] See Figure 1 、 Figure 2 and Figure 3 As shown, in an alternative embodiment of the present invention, the channels between adjacent two heat dissipation fins are oriented towards the air inlet 120.
[0043] Specifically, the trend of the heat dissipation fins is set to face the air inlet 120, so that the airflow inhaled from the air inlet 120 can flow through the channels between adjacent two heat dissipation fins, quickly dissipating heat from the heat dissipation plate 200, thereby effectively dissipating heat from the controller and ensuring that the controller will not overheat during long-term operation. In addition, after the airflow passes through the heat dissipation plate 200, it can hit the chain saw housing 100, and then dissipate heat from the motor along the channels inside the chain saw housing 100, effectively dissipating heat from the motor, and finally discharging from the exhaust port 130.
[0044] It should be noted that the length of the air inlet 120 is greater than the length of the heat dissipation plate 200. By such a setting, part of the air inhaled from the air inlet 120 dissipates heat from the heat dissipation plate 200 on the controller, and the other part directly flows along the channel to the motor and dissipates heat from the motor, so that when working outdoors in hot weather, both the motor and the control board can be kept within a suitable temperature range and the equipment will not be burned out.
[0045] It should also be noted that a wind guide plate can be provided at the air inlet 120 opened on the chain saw housing 100, so that the air inhaled from the air inlet 120 can better dissipate heat from the heat dissipation plate 200, and according to the air volume distribution at the air inlet 120, wind guide plates with different orientations are provided at the air inlet 120, so that part of the airflow directly dissipates heat from the heat dissipation plate 200 of the controller, and the other part of the airflow directly flows along the channels inside the chain saw housing 100 to dissipate heat from the motor, ensuring that both the controller and the motor can be cooled by the cold air flow at the same time.
[0046] It should be noted that the user can set the length of the air inlet 120 according to actual needs, which will not be elaborated here.
[0047] See Figure 1 、 Figure 2 and Figure 3 As shown, in an alternative embodiment of the present invention, the heat dissipation plate 200 is detachably mounted on the controller by bolts.
[0048] Wherein, a heat dissipation silicone grease is provided between the controller and the heat dissipation plate 200.
[0049] Specifically, the heat dissipation plate 200 is detachably mounted on the controller, and in order to improve the heat dissipation efficiency and effect of the heat dissipation plate 200 on the controller, heat dissipation silicone grease is provided between the controller and the heat dissipation plate 200.
[0050] It should be noted that the user can select the specifications of the heat dissipation silicone grease according to actual needs, which will not be elaborated here.
[0051] See Figure 1 、 Figure 2 and Figure 3 As shown in
[0052] Specifically, a battery mounting seat 140 for mounting a lithium battery pack is provided on the chain saw housing 100, and the lithium battery pack is detachably mounted on the battery mounting seat 140, so that it is convenient for the user to use the chain saw device.
[0053] Among them, the user can select the specifications and capacity of the lithium battery pack according to actual needs, which will not be elaborated here.
[0054] See Figure 1 、 Figure 2 and Figure 3 As shown in
[0055] Specifically, a battery heat dissipation hole 150 is provided on the chain saw housing 100. When the lithium battery pack is mounted on the battery mounting seat 140, a part of the lithium battery pack can block the battery heat dissipation hole 150. Thus, when the cooling fan is started, the airflow inhaled from the air inlet 120 can simultaneously dissipate heat from the lithium battery pack, thereby assisting in dissipating heat from the lithium battery pack. Through such a setting, the lithium battery pack can withstand high-temperature environments.
[0056] This embodiment provides a chain saw, including a chain saw heat dissipation and cooling structure.
[0057] Specifically, the chain saw provided in this embodiment has the advantages of the above-mentioned chain saw heat dissipation and cooling structure compared with the prior art, which will not be elaborated here.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
