Description

Cooling-water heating type heater

The present invention relates to a cooling water heating heater, and more particularly, the present invention relates to a cooling water heating heater in which the bubbles inside the heat generating pipe are easily discharged by extending from the top in the state where the outlet portion is mounted, thereby further increasing safety.

The present invention relates to a cooling water heating heater, and more particularly to a cooling water heating heater for heating the cooling water for vehicle interior heating.

Vehicles powered by engines using gasoline, diesel, etc. as the energy source are the most common types of vehicles at present.However, such energy sources for automobiles are not only needed for environmental pollution but also for various reasons such as the reduction of oil reserves. Increasingly, one of the technologies that is closest to the present practical use is a vehicle driven by a fuel cell as an energy source.

However, in a vehicle using such a fuel cell, a heating system using cooling water cannot be used, unlike a vehicle having an engine using a conventional oil as an energy source. That is, in the case of a vehicle driven by an petroleum-based energy source, a very large amount of heat is generated in the engine, and a coolant circulation system for cooling the engine is provided. Had to use. However, since much heat such as that generated in an engine does not occur in a driving source of a vehicle using a fuel cell, there is a limit to using such a conventional heating method.

Accordingly, in fuel cell vehicles, various studies have been made, such as adding a heat pump to an air conditioning system so that it can be used as a heat source, or providing a separate heat source such as an electric heater. Among them, the battery heater can heat the cooling water more easily without significantly affecting the air conditioning system, and is currently widely used in practice.

FIG. 1 shows Japanese Patent Laid-Open No. 2008-056044 ("Heat medium heating device and vehicle air conditioner using the same"), which is one of conventional cooling water heating heaters.

The cooling water heating heater of Japanese Laid-Open Patent Publication No. 2008-056044 has a plate-shaped fin disposed above and below a PTC electrode plate serving as a heat source, and allowing the cooling water to pass through the plate-shaped fin, thereby transferring heat from the PTC electrode plate to the cooling water. It is designed to heat up the cooling water more effectively.

However, such a coolant heating heater has a problem that it is difficult to obtain a sufficient cooling water heating effect, the problem including this will be described again below.

First, since the heating element (PTC electrode plate) enters into a separate part, the number of parts increases, and there is a problem in that volume and weight increase. Second, heat generated from the PTC electrode plate is not completely transmitted to the cooling water, but a part of the heat is transferred to the outside to generate heat loss. Third, various objects such as an insulating layer are present on the heat transfer path from the PTC electrode plate to the cooling water, thereby increasing the heat resistance, and thus reducing the heat transfer efficiency. Fourth, when the cooling water heating heater of this type is mounted on a vehicle, the design of the cooling water pipeline, the electric supply line circuit, and the like becomes complicated, and the actual cooling of the cooling water heating heater itself is difficult.

That is, there is a need for a coolant heating heater capable of effectively heating the coolant, making it easy to manufacture and install, reducing the volume, weight, and cost, and ensuring safety.
