Abstract
The utility model discloses a water-electricity separating heat exchange water jacket, which consists of a plurality of aluminum radiating fins, a plurality of PTC (positive temperature coefficient) heating strips and a water inlet and outlet cover. The aluminum radiating fins are mutually in butt joint to each other to form a water jacket barrel, abutted edges of the aluminum radiating fins are connected with flanges and coated with high-temperature heat-conduction structural sealant, each PTC heating strip is sandwiched between each two aluminum radiating fins, and a screw penetrates between the flanges on each two aluminum radiating fins and is screwed with a nut. The PTC strips are tightly pressed step by step via the screws on the radiating fins, accordingly, during usage, power of the water jacket is quite stable, and insulation of insulating yellow paper of the PTC heating strips cannot be damaged by an elastic fastening method. The water jacket is low in impact current, and starting current of the water jacket is approximately equal to rated current or is 1.3 times larger than the rated current at most. The PTC heating strips are arranged in the water jacket, namely the PTC heating strips are soaked in water, and accordingly the water jacket is low in heat loss compared with a traditional water jacket with external PTC heating strips.
Description
Technical field:
The utility model relates to a kind of electric equipment, relate in particular to a kind ofly heat, the electricity separation heat exchange water jacket of heat exchange.
Background technology:
Present PTC heat exchanger be with PTC with the yellow paper insulation of three floor height temperature insulation after, be compressed on dedicated aluminium alloy water jacket outside by mould; The PTC heating power is passed to water by aluminium alloy with heat.The heat exchanger of this kind structure exists following shortcoming: (1) because of welding during water inlet pipe and water outlet pipe electric welding produce high heat the PTC yellow paper insulation that insulate destroyed, cause electric leakage.(2) fixedly the PTC bar can the part is loosening not to cause tightly that the appliance starting electric current is big because of the pressure inequality causes in the mould extruding, is generally 2～3 times of rated current; Next power instability.(3) fixedly the PTC bar is excessive because of local pressure sometimes in the mould extruding, causes the yellow paper insulation breakage of minor insulation, in use produces electric leakage.(4) the external part thermal loss that causes of PTC bar.
The utility model content:
In order to solve the problems referred to above of utilizing the PTC electronic devices and components to exist in the application of heat exchanger, the purpose of this utility model provides a kind of stable performance, safe in utilization, electricity separation heat exchange water jacket that the thermal efficiency is high.
The technical solution of the utility model realizes in the following manner:
A kind of electricity separation heat exchange water jacket, it is made up of some aluminium radiator fins, some PTC fire-bars, turnover water cover, wherein, between the aluminium radiator fin mutually to being connected into a water mantle, aluminium radiator fin is connected with ring flange to edge fit, and aluminium radiator fin is to edge fit place coating high temperature conductive structure fluid sealant, and the PTC fire-bar is sandwiched between two aluminium radiator fins, penetrate screw between the ring flange on two aluminium radiator fins, the nut of screwing on.
Aluminium radiator fin is six, and six aluminium loose sheet mutually to being connected into a water mantle, and six PTC fire-bars are installed in the water mantle by ring flange and screw, nut.
The turnover water cover connects the water mantle two ends by high temperature conductive structure fluid sealant.
The beneficial effects of the utility model:
1, power stability
Because progressively forcing the PTC bar by the screw on the fin, the utility model presses tightly, so at its power quite stable of use.
2, there is not electric leakage
Press tightly because the utility model is progressively forced the PTC bar by the screw on the fin, this elasticity fastening method does not damage the yellow paper insulation of insulation of PTC bar.Measure with 1000 volts of insulated electro sublists, its insulation against ground resistance is greater than 500 megaohms.
3, dash current is little
Because progressively forcing the PTC bar by the screw on the fin, the utility model presses tightly, this elasticity fastening method fits tightly PTC strip electrode sheet and fin more, in time heat on the PTC sheet is conducted, so its starting current approximates within rated current or rated current 1.3 times.
4, thermal loss is little
Because the utility model PTC bar is built in water jacket, promptly is immersed in the water, so compare with traditional external, thermal loss is little.
Description of drawings:
Fig. 1 is a contour structures schematic diagram of the present utility model.
Fig. 2 is the A-A cut-away view of Fig. 1.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: the utility model is made up of some aluminium radiator fins 1, some PTC fire-bars 3, turnover water cover 4, wherein, between the aluminium radiator fin 1 mutually to being connected into a water mantle, 1 pair of edge fit of aluminium radiator fin is connected with ring flange, 1 pair of edge fit place coating of aluminium radiator fin high temperature conductive structure fluid sealant, PTC fire-bar 3 is sandwiched between two aluminium radiator fins, penetrates screw between the ring flange on two aluminium radiator fins 1, the nut 2 of screwing on.
Be it can also be seen that by Fig. 2: aluminium radiator fin is six, six aluminium loose sheet mutually butt joint organize a water mantle, six PTC fire-bars 3 are installed in the water mantle by ring flange and screw, nut; Turnover water cover 4 connects the water mantle two ends by high temperature conductive structure fluid sealant.
