Dry intelligent direct-reading hot water gauge

Technical field the utility model relates to the electronic intelligence water meter, particularly relates to the dry intelligent hot water gauge.

The background technology hot water gauge is worked for a long time and will be ensured the serviceable life of 4 years under high water temperature condition, and the environment for use temperature that reduces electronic devices and components (main is the direct-reading circuit module) is very crucial.At present, dry intelligent direct-reading hot water gauge structure is: the direct-reading circuit module is arranged between middle clamp plate and lower plate, and directly and the laminating of the annular upper end face of watchcase, the plastic cement collar that the recycling surrounding is sealed is connected and fixed watchcase and translucent cover to lower plate.The shortcoming of this spline structure dry intelligent direct-reading hot water gauge is: heat conductor (comprising: the hot water watchcase, copper pressure ring and gearcase) and lower plate and plastic cement collar between formed confined space, heat between heat conductor and lower plate can't pass, the heat of hot water is by the hot water watchcase, copper pressure ring and gearcase directly are delivered to lower plate rapidly, make temperature between lower plate and middle clamp plate substantially approach the temperature of hot water. cause the direct-reading circuit module be assemblied between middle clamp plate and lower plate to be in for a long time outside normal serviceability temperature scope, accelerate its disabler, greatly shorten its serviceable life, until cause whole intelligent system, scrap.

Utility model content the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes that a kind of thermal diffusivity is good, reliability is high, the dry intelligent hot water gauge of long service life.

The utility model solve the technical problem can be by realizing by the following technical solutions:

Design, make a kind of dry intelligent direct-reading hot water gauge, comprise watchcase and translucent cover, gearcase and copper pressure ring are set in described watchcase; Also comprise lower plate and middle clamp plate between watchcase and translucent cover, and enclose left collar and right collar that hoop connects together both in watchcase and outside, translucent cover joint portion; Described lower plate and middle clamp plate surround for placing the cavity of direct-reading circuit module; Described lower plate contacts with the annular upper end face of watchcase by post and makes to be formed with the space that is beneficial to Air Flow between the two; Offer respectively radiator window on described left collar and right collar; Described space is communicated with radiator window.

Around described lower plate main part and between left collar, right collar, be provided with heat dissipating ring; Described heat dissipating ring is made by aluminium alloy.

Compared with the existing technology, technique effect of the present utility model is: 1. the annular upper end face of lower plate and watchcase is conducive to the space of Air Flow, and this space is by left, the radiator window of right collar is in communication with the outside, through watchcase, the hot water heat that copper pressure ring and gearcase transmit, major part can be dispersed into outside hot water gauge through described space and radiator window, greatly reduce the heat that is delivered to lower plate, thereby reduced the temperature between lower plate and middle clamp plate, guarantee that the direct-reading circuit module works in normal temperature range, guarantee its job stability and reliability and serviceable life, 2. adding of aluminium alloy heat dissipating ring, further accelerate heat to extraneous transmission and distribute.

Embodiment is described in further detail below in conjunction with the preferred embodiment shown in accompanying drawing.

The utility model dry intelligent direct-reading hot water gauge, as depicted in figs. 1 and 2, comprise watchcase 10 and translucent cover 20, interior gearcase 30 and the copper pressure ring 60 of arranging of described watchcase 10; Also comprise lower plate 40 and middle clamp plate 50 between watchcase 10 and translucent cover 20, and enclose left collar 70 and right collar 71 that hoop connects together both in watchcase 10 and translucent cover 20 outsides, joint portion; Described lower plate 40 surrounds the cavity 80 for placing the direct-reading circuit module with middle clamp plate 50; Described lower plate 40 contacts with the annular upper end face of watchcase 10 by post and makes to be formed with the space 101 that is beneficial to Air Flow between the two; Offer respectively

radiator window

701 and 711 on described left collar 70 and right collar 71; Described space 101 is communicated with radiator window 121 and 71.

As shown in Figure 1 to Figure 3, around described lower plate 40 main parts and between left collar 70, right collar 71, be provided with the heat dissipating ring 90 of being made by aluminium alloy, the lower edge of this heat dissipating ring 90 is in described space 101.

During assembling, first lower plate 40, translucent cover 20 are inserted in aluminium alloy heat dissipating ring 90, then by aluminium alloy heat dissipating ring 90(heat dissipating ring 90 structures as shown in Figure 4 four flanges) bend and are fixed on the lower end boss of translucent cover 20, recycle left collar 70, the left collar 70 of right collar 71(, right collar 71 structures respectively as shown in Figure 5 and Figure 6, they are made by plastic cement) be connected and fixed watchcase 10 and aluminium alloy heat dissipating ring 90 and translucent cover 20.

The structure of other member of the present utility model and assembling, for example assembly connection between copper pressure ring 60, gearcase 30 and watchcase 10 etc., identical with the hot water gauge of prior art, repeats no more herein.Difference is, the lower plate of prior art hot water gauge directly overlays the upper surface of watchcase, forms closed structure, therefore is unfavorable for heat radiation, and in the utility model, form several posts (being generally 3) on lower plate 40, by several post distributings ground, with the annular upper end face of watchcase 10, contact, thereby make to form cross-ventilated space 101 between the two, utilize a part to be arranged on the aluminium alloy heat dissipating ring 90 that this interior coefficient of heat conductivity in space 101 is higher passes the heat between lower plate 40 and hot water watchcase 10 simultaneously, again in conjunction with left, the radiator window design of right collar, form an outside heat passage, be beneficial to the dissipation of heat between lower plate 40 and hot water watchcase 10 is gone out, reduce the temperature between lower plate and middle clamp plate, so just realized that the direct-reading module can be in good environment and work.

Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
