Description

A kind of Novel shutter

Technical field

The utility model relates to print field, more specifically to a kind of Novel shutter.

Background technology

The application of UV printing is one of most important content of printing industry.In printing process, surface of the light tube temperature can be raised to 700-800 DEG C, in order to avoid material is overheated, many kinds of measures generally will be taked to cool fluorescent tube, reflection lampshade and base material.Existing conventional cooling way has three kinds: one, air cooling, and the method applies maximum methods now, and cost is lower; Two, install optical sheet additional, infra-red radiation and solidfied material are isolated, be applicable to yielding product; Three, water cooling, installs water jacket additional outside fluorescent tube, and the method is effective.Water cooling is delivered to shutter by making the heat around fluorescent tube, by being transmitted fast by heat by the heat-conducting medium in shutter, ensures the temperature stabilization of lamp operation environment again.In actual use, because shutter heat conduction is not good, temperature in shutter can be caused sharply to rise, affect the normal use of fluorescent tube, if do not solve cooling problem, will the generation of the device security hidden danger such as shutter distortion, fluorescent tube explosion be caused.

Existing shutter generally adopts Double-tube cyclic formula shutter, its structure as shown in Figure 4 and Figure 5, comprise shutter body 1, inlet channel 6 and outlet conduit 7 all pass from shutter body 1, and be communicated with by connecting hose 8, heat-conducting medium flows into from the water inlet of water inlet pipe 6 and flows out from the delivery port of outlet pipe 7, by the heat-conducting medium in conduit, is passed by the heat on shutter.The medium contact face of this conductive structure is less, and heat conduction amount is limited, can not meet the demand of heat conduction well.

Summary of the invention

The purpose of this utility model is to provide a kind of Novel shutter, and it under the prerequisite ensureing self-strength, can increase thermal conductive contact area, heat radiation speed.

Novel shutter described in the utility model, comprise shutter body, the cavity body structure in bar shaped is formed at length direction in the middle part of shutter body, in this cavity, be provided with the back-up block that at least two pieces connect cavity madial walls and lateral wall along its length, be respectively arranged with water inlet in one end of shutter body and delivery port makes this cavity be in communication with the outside.

Novel shutter described in the utility model, owing to having said structure, compared to the cooling structure of existing shutter, cavity body structure adds the thermal conductive contact area of cooling fluid, improve radiating rate, the back-up block increased in cavity enhances the intensity of cavity body structure, meets the requirement to shutter intensity, and then achieve under the prerequisite ensureing shutter self-strength, enhance the radiating effect of shutter.

Detailed description of the invention

In order to explain the technical solution of the utility model further, below in conjunction with accompanying drawing, the utility model is elaborated.

See shown in Fig. 1 to Fig. 3, this Novel shutter, comprise shutter body 1, the cavity body structure in bar shaped is formed at length direction in the middle part of shutter body 1, in this cavity 2, be provided with the back-up block 3 that six pieces connect cavity madial walls and lateral wall along its length, be respectively arranged with water inlet 4 in one end of shutter body and delivery port 5 makes this cavity 2 be in communication with the outside.

Shown in Fig. 4 and Fig. 5, the heat-conducting area S1=2*L*D=2*900*8=14400mm of existing Double-tube cyclic formula shutter ².Heat-conducting area S2=L*A-6*a*b=900*40-6*30*10=36000-1800=34200mm of the present utility model ².The radiating effect of the utility model and existing Double-tube cyclic formula shutter contrasts △ E=S1/S2=14400/34200=2.375.Known, radiating rate of the present utility model is 2 times of existing Double-tube cyclic formula shutter, greatly improves radiating rate.
