DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Embodiment: please refer to Figures 1 to 5 A liquid crystal television with high-efficiency heat dissipation function, comprising a casing 1 and a liquid crystal screen 2 installed on the front of the casing 1. In order to facilitate the description below, the side of the casing 1 close to the liquid crystal screen 2 is defined as the front, and the side of the casing 1 away from the liquid crystal screen 2 is defined as the back.

[0027] The embodiment also comprises a passive heat dissipation mechanism 3 and an active heat dissipation mechanism 4. The active and passive types are combined together, with the function of high-efficiency heat dissipation, so as to quickly dissipate heat of the liquid crystal television, ensure that the heat can be dissipated in time, and the heat dissipation effect is good.

[0028] The passive heat dissipation mechanism 3 will be described in detail below.

[0029] The passive heat dissipation mechanism 3 is fixed on the back of the casing 1. Specifically, the passive heat dissipation mechanism 3 comprises a plurality of heat dissipation fins 301 fixed in parallel and at intervals on the outer back of the casing 1, and a heat dissipation plate 302 fixed on the inner back of the casing 1 for absorbing the heat inside the casing 1. Each heat dissipation fin 301 extends into the casing 1 and is fixedly connected with the heat dissipation plate 302. When the liquid crystal television works, the heat inside the casing 1 is transmitted to the heat dissipation fin 301 through the heat dissipation plate 302, and then exchanged with the surrounding air through the heat dissipation fin 301 to dissipate the heat to the air, thereby dissipating the heat inside the casing 1. By using this heat dissipation mode, the inside of the casing 1 is not communicated with the outside air, so as to avoid the dust, moisture and the like in the outside air from entering the casing 1.

[0030] Preferably, the gaps between the heat dissipation fins 301 form air flow channels for the circulation of air. The air guide assembly 5 is arranged between the active heat dissipation mechanism 4 and the air flow channels, and can guide a portion of the air generated by the active heat dissipation mechanism 4 to the air flow channels, so as to increase the air flow speed of the air flow channels and facilitate heat exchange between the heat dissipation fins 301 and the surrounding air.

[0031] It should be noted that the air guide assembly 5 includes an air guide cover 501 fixed to the back of the casing 1 and located at the upper end of the heat dissipation fins 301. The air guide cover 501 is in communication with the active heat dissipation mechanism 4 via an air conveying pipe 502, which is used to convey a portion of the air generated by the active heat dissipation mechanism 4 to the air guide cover 501. The air guide holes 503 are formed in the bottom of the air guide cover 501 and are adapted to the air flow channels, so as to blow air to the air flow channels, thereby increasing the air flow speed of the air flow channels and quickly dissipating heat to the air.

[0032] The active heat dissipation mechanism 4 will be described in detail as follows:

[0033] The active heat dissipation mechanism 4 is fixed to the top of the casing 1 and extends into the casing 1. Specifically, the active heat dissipation mechanism 4 includes a wind collecting cover 401 fixed to the top of the casing 1. A plurality of fans 402 are mounted on the top of the wind collecting cover 401. The air outlet ends of the fans 402 are in communication with the inner cavity of the wind collecting cover 401, and the air generated by the fans 402 can enter the wind collecting cover 401 when the fans 402 are working. It should be noted that the air conveying pipe 502 is in communication with the wind collecting cover 401, so as to convey a portion of the air to the air guide cover 501.

[0034] The heat conducting plate 403 is fixed to the inner front surface of the casing 1 and is used to absorb heat in the casing 1. A plurality of heat conducting channels are formed in the heat conducting plate 403. The air inlet pipes 404 are fixed to the top of the heat conducting plate 403 and are in communication with the heat conducting channels. The air outlet pipes 405 are fixed to the bottom of the heat conducting plate 403 and are in communication with the heat conducting channels. The air outlet ends of the air inlet pipes 404 extend into the wind collecting cover 401. The air in the wind collecting cover 401 enters the heat conducting channels via the air inlet pipes 404, so as to carry away the heat in the heat conducting channels. The air outlet ends of the air outlet pipes 405 extend to the bottom of the casing 1, so as to discharge the heat in the heat conducting channels to the outside air. When the fans 402 are working, the air flow generated by the fans 402 enters the wind collecting cover 401. A portion of the air flow is conveyed to the air guide cover 501 via the air conveying pipe 502 and is blown to the air flow channels via the air guide holes 503, so as to improve the heat dissipation effect of the heat dissipation fins 301. Another portion of the air flow enters the heat conducting channels via the air inlet pipes 404 and is discharged to the outside air via the air outlet pipes 405, so as to dissipate the heat absorbed by the heat conducting plate 403 to the outside air. This heat dissipation mode makes the inside of the casing 1 not communicate with the outside air, so as to avoid dust and moisture in the outside air from entering the casing 1.

[0035] Preferably, the outer bottom of the casing 1 is fixed with a dust screen 6 for shielding the ports of the exhaust ducts 405, which can avoid the outside dust, mosquitoes and other things from entering the ducts, causing the ducts to be blocked.

[0036] The working principle is as follows:

[0037] When the liquid crystal television needs to be cooled, the fan 402 works, the generated airflow enters the air collecting cover 401, part of the airflow is delivered to the air guiding cover 501 through the air delivery pipe 502, and is blown to the airflow channel through the air guiding hole 503, so that the casing 1 is cooled through the cooperation of the heat dissipation fins 301 and the heat dissipation plate 302. Another part of the airflow enters the heat conducting channel through the air inlet pipe 404, and is discharged to the outside air through the exhaust pipe 405, so that the heat absorbed by the heat conducting plate 403 is dissipated to the outside air, thereby efficiently cooling the liquid crystal television.

[0038] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without limitation, an element preceded by "comprises... a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus.

[0039] Although the embodiments of the present application have been shown and described, it is to be understood that for the purpose of the present application, the embodiments change, modify, replace, and vary in many ways without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
