Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the embodiments and features described herein can be combined with each other unless otherwise specified.

[0020] Figure 1 A schematic diagram of the structure of a cabinet 100 according to one embodiment of this application is shown. See also Figure 1 As shown, the cabinet 100 includes a cabinet body 10. A shelf 20 is provided in the lower part of the cabinet body 10, dividing the interior space into a heater compartment 30 below the shelf 20 and a battery compartment 40 above the shelf 20. A battery pack 60 is installed in the battery compartment 40. A cabinet heating assembly 50 is provided in the heater compartment 30 for heating the battery compartment 40 in the upper space. In specific implementations, various other functional components can also be configured inside the cabinet body 10; this is prior art and will not be detailed in this application.

[0021] See Figure 1 Combination Figure 2 As shown, the cabinet heating assembly 50 includes a heater 51 and an air guide plate 52. The heater 51 is installed on one side of the bottom plate 31 inside the heater compartment 30 in the left-right direction, and includes a housing 511, a heating element 512 (not visible in the figure), and a fan 513. The housing 511 is rectangular, with an air inlet and an air outlet in the front-back direction. The heating element 512 is disposed inside the housing 511, and the fan 513 is disposed at the air inlet of the housing 512. The fan 513 heats the air entering from the air inlet through the heating element 512 and then sends it out from the air outlet. The air guide plate 52 extends along the left and right sides of the heater compartment 30 and is installed inside the heater compartment 30 between the air inlet and air outlet of the heater 51, near the air inlet. See details. Figure 2As shown, the lower end of the air guide plate 52 is supported on the bottom plate 31 of the heater chamber 30. The left and right sides of the air guide plate 52 each form forward-extending side flanges 523, which are used to lock and fix it to the left and right sides of the heater chamber 30. The upper end of the air guide plate 52 also has a forward-extending upper flange 524 that abuts against the bottom of the shelf 20. The upper flange 524 can also enhance the strength of the air guide plate 52. According to different embodiments of this application, the side flanges 523 and the upper flange 524 can also extend rearward relative to the air guide plate 52. See also... Figure 2 As shown, the air guide plate 52 has a first mounting opening 521 with its lower end open on one side of the heater 51. The shape of the first mounting opening 521 is adapted to the shape of the heater 51 to cover it, thereby separating the air inlet and outlet of the heater 51 on one side. The air guide plate 52 also has a second mounting opening 522 with its lower end open on the opposite side of the first mounting opening 521. The shape of the second mounting opening 522 can be the same as the first mounting opening 521, that is, it is also adapted to the shape of the heater 51. See also Figure 3 As shown, the cabinet heating assembly 50 according to the above embodiment of this application forms an air duct 70 via a second mounting port 522 between the air inlet and outlet of the heater 51 by adding an air guide plate 52. Through the action of the fan 513, cold air enters the heater 51 from the air inlet as indicated by the first arrow 81, is heated by the heating element 512, and is blown out from the air outlet of the heater 51. Then, as indicated by the second arrow 82, the hot air exiting from the air outlet of the heater 51 can enter the space without a heater on the other side through the air duct 70 to heat the battery compartment space on the other side, thereby achieving a balanced heating effect. The baffle 21 at the front end of the shelf 20 also enhances the effect of the air duct 70.

[0022] Figure 4 The electrical schematic diagram of the aforementioned cabinet heating assembly 50 is shown. See also... Figure 4 As shown, the heating element 512 is implemented by two parallel PTC heating elements, PTC1 and PTC2. A first temperature relay 514 is connected between the heating element 512 and its power input. The fan 513 includes two parallel fans, FAN1 and FAN2. A second temperature relay 515 is connected between the fan 513 and its power input. The first temperature relay 514 and the second temperature relay 515 control the operation of the heating element 512 and the fan 513, respectively, thereby heating the battery compartment space to the ideal temperature.

[0023] According to the above embodiments of this application, the cabinet heating assembly 50 has an air guide plate 52 installed in the heater compartment 30 near the air inlet of the heater 51. The air guide plate has a first mounting port 521 on the right side corresponding to the heater 51, which covers the heater 51 to separate the air inlet and outlet of the heater 51. A second mounting port 522, with the same shape as the first mounting port 521, is opened on the left side, connecting the air inlet and outlet of the heater 51 to form an air duct 70. Hot air from the outlet of the heater 51 can then pass through this air duct 70 and through the unheated space on the left side, achieving a balanced heating effect. According to different embodiments of this application, the heater 51 can also be installed in the second mounting port 522 on the left side of the air guide plate 52, forming an air duct via the first mounting port 521 on the right side of the air guide plate 52. Furthermore, when the cabinet 100 needs to be used in a lower temperature environment, two heaters 51 can be installed simultaneously in the first mounting port 521 and the second mounting port 522 of the air guide plate 52, making the cabinet 100 more versatile, and the air guide plate 52 can also enhance the heating effect.

[0024] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
