Abstract
The invention discloses a novel instant-heating PTC liquid heater. A heating core is formed by splicing at least three electric heating mechanisms. Each electric heating mechanism comprises a PTC ceramic assembly and an aluminum profile of a bearing bush shape, wherein a heating hole is formed in the aluminum profile, and the PTC ceramic assembly is arranged in the heating hole. Bearing bush inner arcs of the bearing bush-shaped aluminum profiles form an inner pipe hole, and an inner flow-deflecting pipe is arranged in the inner pipe hole. An outer flow-deflecting pipe is communicated with the inner flow-deflecting pipe. According to the novel instant-heating PTC liquid heater, PTC ceramic and flow deflectors are used for achieving the design of spinning water flow, so heat can be dissipated sufficiently; the arc-shaped aluminum structure enables heat of the PTC ceramic to be quickly dissipated outside; stainless steel pipes are used as water pipes to avoid corrosion of aluminum alloy; electrode plates with same width of the PTC ceramic are adopted to avoid generation of electric arcs; the maximum movable gap width between the upper electrode plate or the lower electrode plate and the inner left side or the inner right side of the heating hole is smaller than the electrode edge reserving width on the PTC ceramic, so electrodes on the PTC ceramic will not be exposed outside when the PTC ceramic assembly swings arbitrarily in the heating hole.
