Technical Field

[0001] The utility model relates to the technical field of electronic devices, in particular to an electronic ledger terminal with a heat dissipation function. Background Art

[0002] The main function of the electronic ledger terminal device is to record and manage financial data to realize the electronicization of the ledger. The existing electronic ledger terminal devices adopt a dual-screen design. One screen faces the user and mainly displays commodity information with relatively few operations, resulting in relatively less heat generated by this screen; the other screen faces the staff and performs tasks such as data input, query, and processing, resulting in a relatively high amount of heat generated by this screen.

[0003] In order to save costs, usually one heat dissipation component is used to dissipate heat from the two screens. If the heat generation situations of the two screens are different, using one heat dissipation component may lead to uneven heat dissipation. The screen with a large amount of heat generation may not be able to obtain sufficient heat dissipation, while the screen with a small amount of heat generation may be over-cooled, which may affect the performance and stability of the device. Summary of the Utility Model

[0004] Aiming at the above-mentioned shortcomings of the existing technology, the utility model provides an electronic ledger terminal with a heat dissipation function, which can effectively solve the problem of uneven heat dissipation of the two screens in the existing technology.

[0005] To achieve the above object, the utility model is realized through the following technical solutions:

A support seat is fixedly installed on the top of the bottom plate, and two display screens are symmetrically and internally embedded on the outside of the support seat;

[0007] The heat dissipation component includes two air hoods symmetrically and slidably arranged inside the bottom plate. A plurality of heat dissipation fins are fixedly installed at equal intervals inside the air hood, and the relative side of the heat dissipation fins contacts the support seat. A heat dissipation fan is fixedly installed on one side of the top of the support seat. The air outlet end of the heat dissipation fan is communicated with a three-way pipe. The two ends of the three-way pipe are communicated with a connecting pipe through electromagnetic valves, and the other end of the connecting pipe movably penetrates through the air hood. An air outlet hole is opened on the side of the air hood away from the connecting pipe. A temperature sensor is fixedly installed on the inner wall of one side of the air hood at the corresponding position of the air outlet hole, and the temperature sensor is electrically connected to the electromagnetic valve through the support seat to form a control loop.

[0008] According to the above-mentioned electronic ledger terminal with a heat dissipation function, a number of ventilation grooves are symmetrically and equidistantly arranged on the outside of the air hood with respect to the connecting pipe. Dust-proof nets are arranged inside both the air outlet hole and the ventilation grooves.

[0010] According to the above-mentioned electronic ledger terminal with heat dissipation function, a T-shaped plate is fixedly installed at the bottom of the air hood, and a T-shaped groove for sliding connection with it is provided at the corresponding position on the top of the support base.

Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model will be further described below with reference to the embodiments.

[0022] Embodiment: Refer to Figures 1 to 3 , an electronic ledger terminal with a heat dissipation function, includes a bottom plate 1 and a heat dissipation assembly. A support base 2 is fixedly installed on the top of the bottom plate 1. Two display screens 21 are symmetrically and internally embedded on the outer side of the support base 2. One display screen 21 faces the staff, and the other display screen 21 faces the user;

[0023] The heat dissipation component includes two air hoods 3 symmetrically and slidably arranged inside the bottom plate 1. A plurality of heat sinks 31 are fixedly installed at equal intervals inside the air hood 3, and the relative side of the heat sink 31 contacts the support base 2. One side of the top of the support base 2 is fixedly installed with a cooling fan 32. The air outlet end of the cooling fan 32 is communicated with a three-way pipe 33. Both ends of the three-way pipe 33 are communicated with a connecting pipe 35 through a solenoid valve 34, and the other end of the connecting pipe 35 movably penetrates the air hood 3. An air outlet hole 36 is opened on one side of the air hood 3 away from the connecting pipe 35. A temperature sensor 37 is fixedly installed on the inner wall of one side of the air hood 3 at the corresponding position of the air outlet hole 36, and the temperature sensor 37 is electrically connected to the solenoid valve 34 through the support base 2 to form a control circuit. When heat dissipation is required, the cooling fan 32 is started, so that the air generated by the cooling fan 32 enters the two air hoods 3 through the three-way pipe 33 and the connecting pipe 35, quickly taking away the heat on the heat sink 31. In this process, the temperature of the air will change, and the temperature sensor 37 detects the current air temperature and sends the detection result to the display screen 21, and controls the opening and closing degrees of the two solenoid valves 34 through the display screen 21. When facing the display screen 21 with a large heat generation, the opening and closing degree of the solenoid valve 34 is increased at this time, so as to increase the effective flow area of the connecting pipe 35, so that more air is transported into the air hood 3, more effectively taking away the heat on the heat sink 31 and improving the heat dissipation efficiency; on the contrary, when facing the display screen 21 with a small heat generation, the opening and closing degree of the solenoid valve 34 is reduced at this time, so as to reduce the effective flow area of the connecting pipe 35, so that less air is transported into the air hood 3, avoiding excessive cooling and unnecessary energy consumption while ensuring that the heat on the heat sink 31 can be taken away.

[0024] A plurality of ventilation grooves 4 are symmetrically and equidistantly arranged on the outside of the air hood 3 with respect to the connecting pipe 35. Dust-proof nets 41 are arranged inside the air outlet holes 36 and the ventilation grooves 4. When the temperature of the display screen 21 is not high and the cooling fan 32 does not need to be started, the outside air can enter the inside of the air hood 3 through the ventilation grooves 4 at this time, which helps to improve the heat exchange efficiency between the heat sink 31 and the air, thereby enhancing the heat dissipation effect. Through the design of the dust-proof net 41, it can prevent the outside dust from adhering to the heat sink 31 and avoid reducing the heat dissipation effect.

[0025] A support plate 5 is fixedly installed in the middle of the top of the support base 2. The relative side of the support plate 5 is in sliding contact with the air hood 3, which is used to support and limit the two air hoods 3 to ensure that the heat sinks 31 inside always contact the support base 2.

[0026] A T-shaped plate 6 is fixedly installed at the bottom of the air hood 3. A T-shaped groove 61 is opened at the top of the support base 2 at the corresponding position of the T-shaped plate 6 and is slidably connected therewith. Using the T-shaped design, the T-shaped plate 6 can be prevented from shaking, further improving the installation stability of the air hood 3.

[0027] A through groove 7 is commonly formed in the bottom walls of the two T-shaped grooves 61. A plurality of springs 71 are fixedly installed at equal intervals on the bottom wall of the through groove 7. A U-shaped plate 72 is fixedly installed on the tops of the plurality of springs 71. The opposite side of the U-shaped plate 72 and the T-shaped plate 6 are in sliding contact. A vertical rod 73 is fixedly installed in the middle of the top of the U-shaped plate 72. The top end of the vertical rod 73 slidably penetrates through the support base 2. When in use, the elastic force of the spring 71 pushes the U-shaped plate 72 to move upward. At this time, the opposite side of the U-shaped plate 72 and the T-shaped plate 6 are in contact, so as to be able to limit the position of the T-shaped plate 6, thereby preventing the wind cover 3 from shifting; when it is necessary to disassemble the wind cover 3, by pressing down the vertical rod 73, it drives the U-shaped plate 72 to move simultaneously. At this time, the U-shaped plate 72 no longer limits the position of the T-shaped plate 6, so that the wind cover 3 can be disassembled, which is convenient for cleaning the heat sink 31 inside it, and further improves the heat dissipation effect of the device.

[0028] An inclined surface is formed on the side of the U-shaped plate 72 away from the T-shaped plate 6. When the T-shaped plate 6 slides inside the T-shaped groove 61 in the direction of the radiator fan 32, the inclined surface design enables the U-shaped plate 72 to slide downward, avoiding jamming.

[0029] The working principle of the present utility model is as follows: When heat dissipation is required, the radiator fan 32 is started, so that the wind generated by the radiator fan 32 enters the two wind covers 3 through the three-way pipe 33 and the connecting pipe 35, and quickly takes away the heat on the heat sink 31. During this process, the temperature of the wind will change, and the temperature sensor 37 detects the current air temperature and sends the detection result to the display screen 21. The opening and closing degrees of the two solenoid valves 34 are controlled through the display screen 21. When facing the display screen 21 with a large heat generation, at this time, the opening and closing degree of the solenoid valve 34 is increased, so as to increase the effective flow area of the connecting pipe 35, so that more air is transported into the wind cover 3, and the heat on the heat sink 31 is taken away more effectively, improving the heat dissipation efficiency; on the contrary, when facing the display screen 21 with a small heat generation, at this time, the opening and closing degree of the solenoid valve 34 is reduced, so as to reduce the effective flow area of the connecting pipe 35, so that less air is transported into the wind cover 3, while ensuring that the heat on the heat sink 31 can be taken away, avoiding overcooling and unnecessary energy consumption.

[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model 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 on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
