Description

TECHNICAL FIELD

[0001] The utility model relates to battery cooling technical field more specifically, relate to a kind of battery cooling device. BACKGROUND

[0002] Battery is a kind of chemical power that can be repeatedly charged and used. It stores and releases electrical energy through reversible electrochemical reactions. It mainly includes lead-acid battery, nickel-cadmium battery, lithium-ion battery, lithium iron phosphate battery, etc. Different types of batteries can be selected according to different use occasions and technical characteristics.

[0003] Currently, the battery is usually placed in a protective box to protect it from the external environment, providing protection for the battery. Since the battery generates heat during operation, temperature rise will adversely affect its performance and life, so the protective box has ventilation holes for heat dissipation, and some protective boxes have exhaust fans installed inside to remove hot air from the protective box, accelerating heat exchange and improving the heat dissipation effect of the battery in the protective box.

[0004] If you want to ensure good heat dissipation of the battery in the protective box, you need to ensure that there is enough ventilation space around the protective box. However, due to the limitations and narrowness of the battery installation area, it is often difficult to ensure that there is enough space around the protective box. Some batteries are installed, and the protective box is blocked around the protective box, or the gap around the protective box is very small. In this case, the exhaust fan cannot achieve the desired effect, which greatly affects the heat dissipation performance of the protective box. Poor heat dissipation will directly affect the performance and life of the battery. If multiple fans are installed around the inner wall of the protective box, not only the cost is high, but also some fans are useless in this case, which is a waste of resources. It is heavy and noisy, which is not practical.

[0005] Therefore, it is necessary to provide a battery cooling device to solve the above technical problems. UTILITY MODEL CONTENTS

It effectively ensures the battery's heat dissipation performance in different environments, thereby greatly improving battery performance and lifespan. Furthermore, the protective box of this application is suitable for various installation environments, offering wide applicability and high flexibility.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Please refer to Figures 1-8 A battery cooling device, comprising a protection box 1 for placing a battery and a cover plate 20 arranged thereon, further comprising: a support enclosure 2 arranged on the inner wall of the protection box 1, and the four sides of the support enclosure 2 are connected with the four sides of the inner wall of the protection box 1 respectively; a support seat 3 arranged on the support enclosure 2, which can slide along the guide of the support enclosure 2, and the middle part of the support seat 3 is connected with an inner platform 4; an exhaust fan 5 rotatably arranged on the inner platform 4, and a plurality of limiting mechanisms 6 for limiting the rotating direction of the exhaust fan 5 are arranged on the inner platform 4; a plurality of heat dissipation openings 7 are arranged on the four side walls of the protection box 1 corresponding to the positions of the exhaust fan 5.

[0037] In use, the battery is placed and installed in the interior of the protective box 1, and after the cover plate 20 is covered and the installation is completed, the protective box 1 is placed in the corresponding area of the corresponding equipment. Since the corresponding area of the equipment is relatively limited and narrow, when the position of the exhaust fan 5 in the protective box 1 is just blocked or when the gap in the area is small, the position of the exhaust fan 5 needs to be changed at this time. By sliding the support seat 3 along the support apron 2, the movement of the support apron 2 will drive the inner apron 4 and the exhaust fan 5 to move together, so as to move the exhaust fan 5 to a position outside the protective box 1 that is not blocked or has a larger gap. At the same time, the exhaust fan 5 rotates on the inner apron 4, so that the moved exhaust fan 5 is in the correct orientation, that is, the air outlet of the exhaust fan 5 is directed to the heat dissipation port 7 of the protective box 1. At this time, the exhaust fan 5 can work normally, and the hot air generated by the battery in the protective box 1 is exhausted through the corresponding position of the heat dissipation port 7, thereby ensuring the heat dissipation performance of the battery. It greatly avoids the situation that the position of the exhaust fan 5 is blocked or the gap is small after the protective box 1 and the battery are installed, and the heat dissipation effect cannot be achieved. It can effectively ensure the heat dissipation performance of the battery in different area environments, thereby greatly improving the use performance and service life of the battery. The protective box 1 of the present application can be used in various installation environments, has a wide application range and high flexibility. It prevents the use of multiple fans with high cost and the situation that some fans do no work. It can greatly reduce the self-weight of the protective box 1 and the noise during use, is more practical, meets the use requirements, and can be widely used.

[0038] Then the position of the rotated exhaust fan 5 is fixed and limited by the limiting mechanism 6, which can ensure the stability of the exhaust fan 5 during use and avoid shaking during use to affect the heat dissipation effect. When the direction of the exhaust fan 5 needs to be turned later, the position limitation of the exhaust fan 5 by the limiting mechanism 6 can be operated to turn the direction of the exhaust fan 5. The operation is simple and convenient, meets the use of different directions, and has high practicality.

[0039] The dust filter screen is detachably installed in the exhaust fan 5. The dust filter screen can filter dust and impurities, which can effectively prevent external impurities from entering the interior of the protective box 1, thereby better protecting the battery.

[0040] The protective box 1 is provided with a temperature sensor of the prior art, and the temperature sensor is electrically connected with the exhaust fan 5 through a controller. When the temperature in the protective box 1 exceeds a preset threshold value, the controller starts the exhaust fan 5, thereby increasing the air flow rate and quickly exhausting the hot air in the protective box 1, improving the use performance and service life of the battery. When the temperature in the protective box 1 is lower than the preset threshold value, the exhaust fan 5 does not work, which can greatly save energy consumption, reduce the working time and intensity of the exhaust fan 5, and improve the service life and performance of the exhaust fan 5.
