A heater device with double-sided water flow channels

Abstract

The invention discloses a heater device with a two-side water flow channel. The heater device comprises a heat conduction block, a water inlet pipe and a water outlet pipe. A water inlet channel is formed in the front face of the heat conduction block, and a water outlet channel is formed in the back face of the heat conduction block. One end of the water inlet channel is communicated with a connecting through hole in the heat conduction block, and the other end of the water inlet channel is communicated with the water inlet pipe; one end of the water outlet channel is communicated with the connecting through hole in the heat conduction block, and the other end of the water outlet channel is communicated with the water outlet pipe; and a cavity is further formed in the heat conduction block, arranged between the water inlet channel and the water outlet channel and internally provided with a heater. The heater device can be disassembled to be cleaned, maintaining is convenient, and the condition that an integrated metal heater is replaced by a new integrated metal heater without maintaining after being damaged is avoided; and a heater with an insulation surface layer can be conveniently assembled, and even if electric leakage occurs inside the heater, heated water flow can not be electrified, so that a product to which the heater device is applied is safer and more environmentally friendly, and saves energy.

Description

technical field [0001] The present invention relates to the technical field of heaters, in particular to a heater device with double-sided water flow channels (hereinafter referred to as the heater device). Background technique [0002] At present, heaters are widely used, especially for metal heaters in instant electric water heaters, such as figure 1 As shown, the metal heater and the heating tube are integrated. After the damage, due to the high repair cost, it is generally not repaired. Replacing a new metal heater is a huge waste of resources. The metal heater used in the instant water heater, due to the limitation of space, the length of the heating tube in the metal heater is limited, and its surface heat load is very large, which is easy to generate scale. Due to the scale, the heat energy of the metal heater cannot be very good The heat is emitted from the wall of the heating tube to the heated water, which will cause the temperature in the metal heater tube to be ...

Problems solved by technology

[0002] At present, heaters are widely used, especially for metal heaters in instant electric water heaters, such as figure 1 As shown, the metal heater and the heating tube are integrated. After the damage, due to the high repair cost, it is generally not repaired. Replacing a new metal heater is a huge waste of resources.

The metal heater used in the instant water heater, due to the limitation of space, the length of the heating tube in the metal heater is limited, the heat load on the surface is very large, and it is easy to generate scale. Due to the scale, the heat energy of the metal heater cannot be very good The heat is emitted from the wall of the heating tube to the heated water, which will cause the temperature in the metal heater tube to be too high and cause damage

In addition, since the heating tube wall of the metal heater is in direct contact with the heated water flow, the leakage phenomenon of the metal heater will cause the heated water flow to be electrified, and there is a large safety hazard
