Description
Technical field
The utility model relates to a kind of power supply, relates in particular to a kind of waterproof power supply.
Background technology
On the electronic circuit board in traditional waterproof power supply heat sinking the electronic power semiconductor device is installed, conducts the heat on the shell by radiator, and radiator is only fixing in vertical direction, and fail closely to contact with shell, thereby cause dispelling the heat slow problem; The waterproof power supply that has is installed in electronic semiconductor components on the shell in order to allow the electronic semiconductor components heat radiation, though solved heat dissipation problem like this, has influenced the normal arrangement of Switching Power Supply, causes interference.In order to overcome above-mentioned defective, we have developed a kind of improved waterproof power supply.
Summary of the invention
The purpose of this utility model is to provide a kind of waterproof power supply, effectively solves because radiator is only fixing in vertical direction, and fails closely to contact the slow problem of the heat radiation that causes with shell; Effectively solve electronic semiconductor components is installed in the normal arrangement that influences Switching Power Supply that causes on the shell, the problem that causes interference.
The technical scheme that its technical problem that will solve the utility model adopts is: a kind of waterproof power supply, comprise metal shell 1, electronic circuit board 2, power type semiconductor electronic component 3, radiating element 4, power type semiconductor electronic component 3 and radiating element 4 are close to screw and are connected, and it is characterized in that: described metal shell 1 is close to screw 5 with described radiating element 4 and is connected.
Leave the gap between described radiating element 4 and the described electronic circuit board 2.
The beneficial effects of the utility model are:
The utility model has adopted above-mentioned technical scheme, the power type semiconductor electronic component of this waterproof power supply dispels the heat by radiating element, radiating element closely is connected with screw with metal shell, so just can guarantee that radiating element fully contacts with metal shell, transfer heat on the metal shell, thereby transfer heat in the air, radiating rate is fast, and layout is convenient; And leave the space between radiating element and the electronic circuit board, can guarantee that electronic circuit board is not subjected to the influence of radiating element high temperature.Can effectively solve like this because radiator is only fixing in vertical direction, and fail closely to contact the slow problem of the heat radiation that causes with shell; Effectively solve electronic semiconductor components is installed in the normal arrangement that influences Switching Power Supply that causes on the shell, the problem that causes interference, and the utlity model has characteristics simple in structure, easy for installation.
Description of drawings
Figure is perspective view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail:
Referring to accompanying drawing, the utility model comprises metal shell 1, electronic circuit board 2, power type semiconductor electronic component 3, radiating element 4, power type semiconductor electronic component 3 and radiating element 4 are close to screw and are connected, and it is characterized in that: described metal shell 1 is close to screw 5 with described radiating element 4 and is connected.
Leave the gap between described radiating element 4 and the described electronic circuit board 2.
Power type semiconductor electronic component 3 in the utility model and radiating element 4 are close to screw and are linked, metal shell 1 is close to screw 5 with radiating element 4 and is connected, during work, described power type semiconductor electronic component 3 transfers heat on the metal shell 1 by radiating element 4, described radiating element 4 is owing to be close to metal shell 1, guaranteed that both have sufficient contact-making surface, so heat can pass to fully on the described metal shell 1; And leave the space between described radiating element 4 and the electronic circuit board 2, can guarantee that described electronic circuit board 2 is not subjected to the influence of radiating element high temperature.
Like this simple in structure, easy for installation can effectively solve because radiator is only fixing in vertical direction, and fails closely to contact the slow problem of the heat radiation that causes with shell; Effectively solve electronic semiconductor components is installed in the normal arrangement that influences Switching Power Supply that causes on the shell, the problem that causes interference.
Description by above-mentioned structure and principle; the person of ordinary skill in the field is to be understood that; the utility model is not limited to above-mentioned embodiment; adopt the improvement of techniques well known on the utility model basis and substitute and all drop on protection range of the present utility model, should be limited by each claim.
