[0018] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

In addition, it should be noted that when an element is referred to as being "connected", "coupled", or "linked" to another element, it can be directly connected, coupled, or linked to the other element or intervening elements can also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of description and illustration only and do not limit the present application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0021] Referring to Figure 1 , Figure 1 A structure schematic diagram of a cooling device is shown. The cooling device comprises a box body 1 and a plurality of cooling fans 2. The box body 1 is provided with a plurality of air outlets adapted to the cooling fans 2. The cooling fans 2 are fixedly installed on the plane of the box body 1. The cooling fans 2 discharge cold air or hot air through the air outlets, and the air flow directions of the cooling fans 2 installed on the opposite planes of the box body 1 are the same. The box body 1 is internally provided with a support for placing an object to be cooled.

[0022] In the embodiment, the object to be cooled can be a furnace temperature tester. The box body 1 can be a rectangular box body, a cylindrical box body, a rhombic box body, a circular box body, or an irregularly shaped box body, etc., and is preferably a rectangular box body, so that the cooling fans are more easily arranged to form a convection air flow to take out the heat in the box body. By way of example and not limitation, the outer dimensions of the box body 1 are 300 mm in length, 260 mm in width, and 240 mm in height.

[0023] For the rectangular box body, the box body 1 comprises six planes, i.e., a bottom plane, a top plane, a left side plane, a right side plane, a front side plane, and a rear side plane (it should be understood that the front and rear, left and right here are the relative relationships between the planes when the box body is normally placed, and are not specifically referred to). One or more air outlets can be provided on each plane, and one or more cooling fans 2 can be provided on each plane. The cooling fans 2 can be bolted to the planes of the box body 1. Alternatively, the cooling fans 2 can be installed on the inner side of the box body 1, or can be provided on the outer side, which is not limited.

[0024] The heat dissipation fan 2 is connected with a power supply (such as a 220V power supply) to electrically drive the heat dissipation fan 2 to work. The heat dissipation fan 2 drives the fan blades to rotate in a default direction under the action of current to drive the airflow on one side of the heat dissipation fan 2 to flow to the other side. When the heat dissipation fan 2 is located on the side of the box body 1 outside, the airflow on one side flows to the side inside the box body 1, and the heat dissipation fan 2 discharges the cold air outside the box body 1 to the inside of the box body 1; when the heat dissipation fan 2 is located on the side inside the box body 1, the airflow on one side flows to the side outside the box body 1, and the heat dissipation fan 2 discharges the hot air inside the box body 1 to the outside of the box body 1. Further, the two heat dissipation fans 2 installed on the opposite planes of the box body 1 have the same air discharge airflow direction, for example, the air discharge airflow direction of the heat dissipation fan 2 on the left side is from left to right (i.e. discharging cold air), and the air discharge airflow direction of the heat dissipation fan 2 on the right side is also from left to right (i.e. discharging hot air), so that the two heat dissipation fans 2 form a convection airflow, which can more efficiently discharge the heat inside the box body 1. It can be understood that the cold air and the hot air in the embodiment are the relative relationship between the airflow temperatures on the opposite planes, rather than a specific indication. For example, if the temperature of airflow A is higher than that of airflow B, then airflow A is hot air and airflow B is cold air.

[0025] The support is used to place the object to be cooled, which can be a support structure such as a bracket or a support plate, so that the object to be cooled can be placed in the middle of the inside of the box body 1. Optionally, the bracket or the support plate can be a hollow structure to reduce the obstruction to the air discharge airflow. It should be understood that the box body 1 is provided with an openable structure such as a box door or a box cover for placing the object to be cooled inside the box body 1.

[0026] wherein, Figure 2 A perspective structural schematic diagram of the cooling device provided by the embodiment is shown, and it should be understood that, Figure 2 only a part of the structure is shown, and specific structures such as heat dissipation fans can be referred to Figure 1 as shown. As Figure 2 shown, a plurality of heat dissipation fans 2 are respectively fixedly installed on the bottom surface, the top surface, the left side surface and the right side surface of the box body 1, and the air discharge airflow directions between the plurality of heat dissipation fans 2 respectively installed on the bottom surface and the top surface of the box body 1 are the same, and the air discharge airflow directions between the plurality of heat dissipation fans 2 respectively installed on the left side surface and the right side surface of the box body 1 are the same. The heat dissipation fans 2 on the bottom surface and the top surface of the box body 1 form a convection airflow, and the heat dissipation fans 2 on the left side surface and the right side surface of the box body 1 form a convection airflow, so as to improve the heat discharge efficiency of the box body 1, thereby improving the cooling efficiency of the object to be cooled.

[0027] The heat dissipation fan 2 installed on the bottom surface of the box 1 discharges cold air through the air outlet, and the heat dissipation fan 2 installed on the top surface of the box 1 discharges hot air through the air outlet. Due to the gas characteristics of hot air rising and cold air sinking, that is, the air temperature at the bottom surface of the box 1 is lower than that at the top surface of the box 1, the embodiment discharges cold air from the bottom surface of the box 1 and discharges hot air from the top surface of the box 1, thereby further improving the heat dissipation effect and cooling efficiency.

[0028] The electrical connection between the plurality of heat dissipation fans 2 is in series. The plurality of heat dissipation fans 2 are connected in series to realize series control of the heat dissipation fans 2 and improve the convenience of wiring and control.

[0029] Illustratively, when the furnace temperature tester needs to be cooled, the furnace temperature tester is placed on the support, the heat dissipation fan 2 is powered on to drive the heat dissipation fan 2 to work, and the heat dissipation fan 2 carries out heat in the box 1 with the convection air flow, thereby improving the cooling efficiency of the furnace temperature tester.

[0030] Optionally, the box 1 is provided with a plurality of heat dissipation holes. The heat dissipation holes are arranged at a predetermined interval on the box 1 to improve the heat dissipation efficiency in the box 1.

[0031] Optionally, the material of the box 1 is aluminum. The aluminum has heat absorption and high heat dissipation characteristics, which can meet the heat dissipation demand of the box 1; at the same time, the aluminum has wear-resistant characteristics, which improves the service life of the cooling device.

[0032] In some embodiments, as shown in Figure 2 The support is a drawer 3, the drawer 3 is in sliding connection with the inner side surface of the box 1, the box 1 is provided with an opening matched with the drawer 3, and the bottom surface of the drawer 3 is a hollow structure.

[0033] In the embodiment, the drawer 3 can enter or exit the inside of the box 1 in a push-pull manner through the sliding connection with the box 1, so as to place or take the cooled object without the user's hand entering the inside of the box 1, thereby improving the operation convenience. The cooled object is placed on the bottom surface of the drawer 3, which is a hollow structure, so as to reduce the air flow resistance and improve the overall heat dissipation efficiency of the cooled object.

[0034] Optionally, the drawer 3 is provided with a buckle structure to fix the cooled object.

[0035] In some embodiments, the outer side surface of the box 1 is fixedly connected with a temperature control switch, the inside of the box 1 is fixedly connected with a temperature sensor, and the temperature control switch is in communication connection with the temperature sensor and the plurality of heat dissipation fans 2.

[0036] In the embodiment, the temperature sensor is used to detect the ambient temperature inside the box 1, and can also detect the surface of the object to be cooled. The temperature control switch controls the opening or closing of the cooling fan 2 according to the temperature detected by the temperature sensor.

[0037] Optionally, when the temperature value detected by the temperature sensor is greater than the preset temperature value, the temperature control switch opens the plurality of cooling fans 2; when the temperature value detected by the temperature sensor is not greater than the preset temperature value, the temperature control switch closes the plurality of cooling fans 2. The temperature control switch receives the temperature value detected by the temperature sensor, and automatically opens or closes the cooling fan 2 according to the actual temperature condition, so as to reduce the manual operation in the cooling process.

[0038] In some embodiments, the outer side of the box 1 is further fixedly connected with a display screen 4, which is in communication connection with the temperature sensor. The display screen 4 receives the temperature value detected by the temperature sensor and intuitively displays it to the user, so that the user can intuitively understand the cooling state of the object to be cooled, and eliminate the risk of scalding.

[0039] As an example but not limitation, when the furnace temperature tester needs to be cooled, the drawer 3 is pulled out by the handle, the furnace temperature tester is placed in the drawer 3, and the furnace temperature tester is fixed by the buckle structure, and then the drawer 3 is pushed into the box 1. The temperature sensor detects the temperature value inside the box, and if the temperature value is greater than 30℃, the temperature control switch automatically opens the cooling fan 2 until the temperature value is not greater than 30℃, and then the cooling fan 2 is closed; during cooling, the display screen 4 displays the temperature value detected by the temperature sensor. After the cooling fan 2 stops running, the drawer 3 is pulled out by the handle, and the furnace temperature tester is taken out, and the cooling of the furnace temperature tester is completed. The cooling device can realize rapid cooling of the furnace temperature tester, shorten the cooling waiting time, improve the SMT mounting production efficiency, and prolong the service life of the furnace temperature tester.

[0040] The technical features of the above embodiments can be combined in any way. In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0041] The above embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which are within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
